How to Obtain U.S. and Canadian Citizenship: Requirements and Procedures for Dual Citizenship Applications

In recent years, the demand for information on how to obtain US and Canadian citizenship in Vietnam has sharply increased. According to annual immigration data, both the US and Canada are among the countries with the highest number of immigrants globally, with hundreds of thousands of naturalization applications approved each year. This shows that opportunities exist, but not everyone fully understands the path.

Many Vietnamese people seek information about US citizenship, Canadian citizenship, or the possibility of dual US – Canadian citizenship with the desire to live stably, enjoy healthcare and education benefits, and freedom of movement between the two leading North American developed nations. The good news is that both the US and Canada allow dual citizenship, meaning you are not required to renounce your original citizenship if you meet the conditions under the law.

This article will help you understand:

• Conditions and process for obtaining US and Canadian citizenship

• Key differences between the two naturalization systems

• Practical benefits of dual citizenship

• Legal obligations you need to be aware of

If you are considering a long-term future in North America, this is a foundational guide to help you determine the right path and avoid common misunderstandings from the outset.

Part 1: Dual US-Canada Citizenship: Essential Knowledge

Step 1: Permanent Residency Requirements for Naturalization

Proof of legal permanent residency

This is a fundamental step in how to obtain US and Canadian citizenship that many Vietnamese people often do not fully understand.

• You must have a permanent resident card:

  • In the US, it's a Green Card (Permanent Resident Card).

  • In Canada, it's a PR Card (Permanent Resident).

• Permanent residency must be valid and not violate immigration laws.

• The actual period of residence in that country must meet the minimum legal requirement.

If you were not born in the US or Canada, and do not have parents who are citizens of these two countries, the most common path is: apply for an immigration visa → become a permanent resident → after sufficient time, apply for naturalization. This process can take anywhere from a few years to nearly 10 years, depending on the case type.

Minimum residency period for citizenship application

This is a crucial factor when learning about US citizenship requirements or Canadian citizenship requirements.

• For US citizenship:

  • Minimum 5 years of permanent residency (or 3 years if married to a US citizen).

  • Must be physically present in the US for the required number of days.

• For Canadian citizenship:

  • Must have lived in Canada for at least 3 years within the 5 years preceding the application.

  • Must fulfill tax obligations if required to file taxes.

If you leave the country for too long during your permanent residency, your naturalization application may be delayed or rejected.

No “shortcuts” for US – Canada dual citizenship

Many people assume that because the US and Canada are neighboring countries, obtaining dual US and Canadian citizenship would be easier. The reality is quite the opposite.

• Each country has its own distinct immigration laws.

• You must meet all naturalization requirements for each country independently.

• There is no automatic dual citizenship program simply because you are already a citizen of the other country.

Both countries allow dual citizenship, but "allowed" does not mean "easy to achieve." You must complete the entire process like any other immigrant.

Practical roadmap to increase success rate

If your goal is how to obtain US and Canadian citizenship, consider a strategic approach:

1. Choose a starting country that aligns with your personal profile.

2. Complete the process of becoming a legal permanent resident.

3. Maintain stable residency, comply with laws, and pay taxes fully.

4. After successful naturalization, then consider the possibility of applying for residency and naturalization in the other country.

A correct mindset from the beginning will save you many years of waiting and help avoid unnecessary legal risks.

Step 2: How to Legally Obtain a US Green Card

Understanding the role of the Green Card

If you were not born in the US and do not have parents who are US citizens, the mandatory step in how to obtain US citizenship is to get a Green Card.

A Green Card allows you to:

• Become a legal permanent resident in the US

• Live and work indefinitely

• Be eligible to apply for US citizenship after meeting residency requirements

Without a Green Card, you cannot begin the naturalization process.

Three common paths to obtain a Green Card

Here are the 3 main categories most frequently applied in practice when advising on US immigration cases:

1. Family-based sponsorship

This is the most common path for Vietnamese people.

• Spouse is a US citizen

• Parents, children are US citizens

• Some cases of siblings

• Relatives who are permanent residents can also sponsor, but the waiting time is longer

This category prioritizes close family relationships and requires proof of legitimate and transparent relationships.

2. Employment in the US

You can apply for a Green Card through an employer if:

• A US business proves it cannot find suitable local workers

• You possess skills, qualifications, or experience that meet the requirements

The employment-based category is often suitable for individuals with high qualifications, specialized skills, or working in fields with labor shortages.

3. Investment immigration

Investment programs require:

• Minimum investment amount as per current regulations (typically from $800,000 USD to $1,050,000 USD depending on the region)

• Job creation for US citizens

• Legitimate and clearly proven source of funds

This category is suitable for investors with strong financial capacity who wish to immigrate faster.

Green Card is a prerequisite before applying for citizenship

After obtaining a Green Card, you need to:

• Maintain continuous permanent residency for at least 5 years (or 3 years if married to a US citizen)

• Reside physically for the number of days required by law

• Comply with laws and fulfill tax obligations

Only when these conditions are met will you be eligible to apply for citizenship.

Step 3: Permanent Residency Requirements for Canadian Citizenship

Permanent Resident (PR) status is mandatory

If you were not born in Canada and are not a Canadian citizen, the first step in how to obtain Canadian citizenship is to become a Permanent Resident (PR).

Permanent residency allows you to:

• Live and work legally in Canada indefinitely

• Enjoy many benefits almost equivalent to citizens

• Be eligible to apply for Canadian citizenship after meeting residency requirements

Without PR, you cannot submit a naturalization application.

Fulfill actual residency period

This is the most important condition when considering Canadian citizenship requirements.

You must:

• Be physically present in Canada for at least 1,095 days (i.e., 3 years) within the 5 years preceding the application date

• This period is calculated based on the number of actual days present, not just the PR validity period

If you leave Canada for too long, your residency days may not meet the eligibility criteria, leading to rejection or further delays.

Fulfill tax obligations fully

Canada places particular emphasis on the financial responsibility of naturalization applicants.

You need to:

• File and pay personal income tax for at least 3 years during the aforementioned 5-year period (if required to file taxes)

• Ensure your tax records are transparent and free of serious errors

Failure to meet tax obligations is a common reason for application delays.

No legal or immigration issues

To be eligible for citizenship, you:

• Are not currently under investigation for immigration fraud

• Are not subject to review for revocation of permanent resident status

• Do not have a deportation order

Only when your immigration record is "clean" and valid can you proceed with the naturalization process.

Practical considerations for Vietnamese looking to immigrate to Canada

If your goal is how to obtain US and Canadian citizenship, Canada is generally considered to have a clearer, more transparent, and more predictable path in terms of processing times. However, that does not mean it is simple.

A safe strategy is to:

1. Ensure continuous residency.

2. File taxes fully from the first year of income.

3. Avoid any legal risks related to your immigration application.

Canadian citizenship is not difficult if you follow the rules and prepare early. But even a small mistake can extend the waiting time by several years.

Step 4: Tax Regulations for US Citizenship

US citizens are required to file taxes annually

A very important point in the journey of how to obtain US and Canadian citizenship that many Vietnamese often do not anticipate: once you are a US citizen, you must file taxes every year, no matter where you live.

Specifically:

• The US taxes based on worldwide income.

• Even if you live in Vietnam, Canada, or any other country, you must still file a tax return with the US Internal Revenue Service (IRS).

• This obligation applies for life, unless you formally renounce your citizenship.

Real-world example: if you live and work in Canada for 1 year, you must still file taxes in the US, and may also have to file taxes in Canada.

US-Canada tax treaty helps avoid double taxation

Many people worry about "double taxation" when they have dual US-Canada citizenship. In reality, the two countries have signed a tax treaty to avoid double taxation.

How it works:

• You file taxes in your country of primary residence.

• Taxes paid in this country may be deducted or credited against taxes in the other country.

• This means you don't have to pay taxes twice on the same income.

However, filing is still mandatory, even if the additional tax owed is $0.

Canadian citizens only file taxes based on residency

Unlike the US, Canada taxes based on actual residency status.

This means:

• If you are a Canadian citizen but live and work in the US, you primarily file taxes in the US.

• You only have to file taxes in Canada for the period you actually resided in Canada.

This difference is very important when considering US or Canadian citizenship in a long-term strategy.

Practical considerations for those planning dual citizenship

Before pursuing US and Canadian citizenship, you should:

1. Understand the long-term tax obligations of US citizens.

2. Plan your finances and keep transparent income records.

3. Consult an international tax expert if you have income in multiple countries.

Citizenship brings great benefits, but also serious financial responsibilities. Thorough preparation from the start will help you avoid tax penalties or legal violations later on.

Step 5: Travel tips with two passports

Understand the rules for using two passports

Once you have completed the process of obtaining US and Canadian citizenship and possess dual US-Canada citizenship, you will typically have two valid passports. This offers many travel advantages, but also comes with mandatory rules that must be followed.

Basic principles:

• When entering or exiting the US, you must use your US passport.

• When entering Canada, you must use your Canadian passport.

• Do not arbitrarily choose the "more convenient" passport if the national law requires the use of that country's citizen passport.

Violating these regulations can result in warnings, delays, or difficulties with future immigration procedures.

Risk of passport retention upon entry

Some countries have specific regulations for dual citizens.

You may encounter situations such as:

• Being asked to explain your dual citizenship status.

• Having one of your passports temporarily held while information is clarified.

• Being required to present both passports to prove your travel history.

This is not common, but it can happen if the declared information is unclear or shows inconsistencies.

Always check entry policies before traveling

Before every international trip, especially when holding US citizenship or Canadian citizenship, you should:

1. Review the entry regulations of your destination country for dual citizens.

2. Check visa requirements for each passport.

3. Ensure your airline ticket information matches the passport you will use for entry.

A practical strategy is to use the same passport for the entire journey related to one country, avoiding switching passports midway, which can cause confusion in entry and exit data.

Part 2: How to apply for US citizenship: Requirements & procedures

Step 1: US citizenship requirements

If you are a Canadian citizen and are looking into how to obtain US and Canadian citizenship, the first step is to determine if you are eligible to apply for US citizenship. Below are 3 common legal pathways according to the United States Citizenship and Immigration Services (USCIS).

1. Naturalization after 5 years of permanent residency

This is the most common category.

You are eligible if:

• You have a green card (US permanent resident).

• You have continuously resided in the US for at least 5 years.

• You have been physically present for the required number of days.

• You have not committed serious legal violations and have fulfilled your tax obligations.

This is a form of naturalization through long-term residency and integration.

2. Citizenship through US citizen parents

You may have been a US citizen at birth, even if born in Canada, if:

• Your biological father or mother was a US citizen at the time of your birth.

• Or your lawful surrogate mother was a US citizen (in some legally permissible cases).

• You meet the requirements for the parent's prior physical presence in the US under citizenship law.

This is known as citizenship through parents. Many people don't realize they fall into this category until they review their family records.

3. Naturalization after 3 years of marriage to a US citizen

You can shorten the waiting period if:

• You are legally married to a US citizen.

• You have a green card and have lived with your spouse for at least 3 years.

• You maintain a bona fide and legal marriage throughout this period.

This is the "naturalization for spouses" category, but USCIS thoroughly scrutinizes the authenticity of the relationship.

Important note about previously renouncing US citizenship

If you have previously formally renounced your US citizenship, you are almost certainly unable to reapply for citizenship.

The only exception:

• You renounced citizenship before age 18.

• You notified the US Department of State of your desire to reclaim citizenship within 6 months after turning 18.

Beyond this specific case, reapplying for citizenship is almost impossible.

Practical experience when evaluating eligibility

Before submitting your application for US citizenship, you should:

1. Carefully check your permanent resident status and actual residency period.

2. Review your tax records and travel history.

3. Clearly identify which naturalization category you fall under to prepare the correct documents.

Applying under the correct category from the start helps expedite the review process and reduces the risk of rejection. When pursuing dual US-Canada citizenship, understanding each country's requirements is a key factor for long-term success.

Step 2: US naturalization requirements for 5-year permanent residents

1. Must be 18 years of age or older

• You must be 18 years old at the time of application.

• Minors' applications fall under a different category and do not follow this standard naturalization process.

This is a basic but mandatory requirement.

2. Must have had a green card for at least 5 years

• You must have been a legal permanent resident (Green Card holder) for a minimum of 5 years.

• Your green card must be valid, and your residency status must not have been interrupted.

If there are issues with your green card or if you have violated permanent residency conditions, your naturalization application may be delayed.

3. File the application in the correct place of residence

• You must file your application in the authorized jurisdiction where you actually reside.

• You must have resided in that state or district for at least 3 months before filing your application.

This helps ensure the application is processed by the correct office and avoids having it returned.

4. Continuous residence and physical presence

This is often a source of confusion.

You must:

• Reside continuously in the US for 5 years since obtaining your green card.

• Not leave the US for more than 6 months for each extended departure.

• Be physically present in the US for at least 30 months out of the total 5 years before filing your application.

If you leave the country for too long, your continuous residency may be considered interrupted.

5. English language proficiency and civics knowledge

You need to:

• Read, write, and speak basic English.

• Have knowledge of US history and government (civics test).

This exam is mandatory, except for some age and residency-based exemptions.

6. Good moral character

USCIS evaluates:

• Compliance with laws.

• Full tax compliance.

• Honesty in immigration records.

• Respect for the US Constitution and principles.

Serious criminal violations or fraud can make you ineligible.

Practical experience before filing an application

Before officially applying for US citizenship, you should:

1. Review your entire entry and exit history for the past 5 years.

2. Ensure tax records are complete and accurate.

3. Prepare in advance for the English and civics tests.

Naturalization is not just an administrative procedure, but the final step in the immigration journey. Thoroughly preparing each condition will help streamline the review process and increase the chances of success when pursuing the long-term goal of dual US-Canada citizenship.

Step 3: US Naturalization for Spouses after 3 Years

1. Must have a green card and 3 years of permanent residency

In most cases, you need to:

• Be 18 years of age or older.

• Be a permanent resident (Green Card holder) for at least 3 years.

• Be legally married to and living with a U.S. citizen spouse throughout those 3 years.

The marriage must be genuine and maintained until the naturalization interview.

2. Continuous residency and physical presence

You must meet all of the following conditions:

• Reside continuously in the U.S. for 3 years after obtaining your green card.

• Not be absent from the U.S. for more than 6 months for any extended departure.

• Be physically present in the U.S. for at least 18 months within the total 3 years preceding the application date.

Excessive time spent abroad may interrupt residency requirements.

3. File application at correct place of residence

• You must have resided in the state or district where you file your application for at least 3 months prior to filing.

• The application must be filed with the correct authority based on your actual place of residence.

Filing in the wrong jurisdiction may result in the application being returned or delayed.

4. Meet English and civics knowledge requirements

Similar to the 5-year category, you need to:

• Read, write, and speak basic English.

• Pass a test on U.S. history and government.

Some exemptions may apply based on age and length of residency.

5. Ensure good moral character

USCIS will review:

• History of legal compliance.

• Full tax compliance.

• Truthfulness in immigration records.

Any acts of marriage fraud can lead to denial and long-term impacts on immigration status.

6. Special circumstances: spouse working abroad

If your U.S. citizen spouse works abroad for at least 1 year for:

• The U.S. government

• The U.S. military

• Or an organization qualified under law

You are not required to meet the minimum 3-year residency period as usual. However:

• You must still have a valid green card.

• You must demonstrate intent to reside in the U.S. immediately after being granted citizenship.

• You must intend to return to the U.S. when your spouse's work abroad ends.

Practical experience before filing your application

If your goal is dual US-Canada citizenship, the spouse category shortens the timeline but is not "easy."

Before applying, you should:

1. Carefully check your entry and exit history for the past 3 years.

2. Prepare proof of genuine marriage (joint finances, joint residence, joint taxes).

3. Review tax records and criminal history (if any).

Following the correct process and thorough preparation from the start will facilitate the U.S. citizenship application process, creating a solid foundation if you are building a long-term immigration strategy for both the U.S. and Canada.

Step 4: U.S. Citizenship for Children Born in Canada

1. Child can automatically be a U.S. citizen at birth

Generally, if:

• At least one parent is a U.S. citizen at the time the child is born

• And that parent meets the legal requirements for prior residency in the U.S.

Then a child born in Canada may still be recognized as a U.S. citizen from birth, without needing a green card.

However, the parent(s) must prove they lived in the U.S. for a minimum period before the child's birth (this period varies depending on the case).

2. Regulations are very complex and depend on many factors

Determining citizenship through parents depends on:

• Whether the child was born in or out of wedlock

• The time the child was born (laws change over time)

• The time the parent(s) were born

• Whether one or both parents were U.S. citizens at the child's birth

In some cases, DNA testing may be required to prove a biological relationship if records are unclear.

This is the most confusing part when researching U.S. citizenship requirements for children.

3. Cases where parents naturalize after the child is born

If parents become U.S. citizens after their child is born, the child may still qualify if:

• Under 18 years of age at the time of the parent's naturalization

• Had a green card before turning 18

• Residing in the U.S. under the legal custody of the parent(s)

If these conditions are met, the child may automatically become a U.S. citizen without needing to file a separate naturalization application.

4. Adopted children

If you adopt a Canadian child and wish to apply for U.S. citizenship for an adopted child, you must meet:

• The adoption was finalized before the child turned 16

• The adoptive parent(s) have legal custody

• The child was legally admitted to the U.S. as an orphan or under the Hague Adoption Convention

The adopted child category has specific requirements and needs very thorough application preparation.

Practical tips for families planning dual citizenship

If your goal is dual US-Canada citizenship for the whole family, please:

1. Verify the citizenship status of the parent(s) before the child's birth.

2. Keep complete records of U.S. residency (proof of education, employment, tax filings).

3. Seek expert advice before filing an application to confirm the child's citizenship.

Citizenship for children can be an automatic right, but only if you clearly understand and correctly prove the conditions under the law. Early preparation will help your child have a solid legal foundation from birth.

Step 5: How to Apply for U.S. Citizenship

1. Select the correct application form based on your citizenship category

Depending on how you apply for U.S. citizenship, the form will vary:

• For naturalization after 3 or 5 years of permanent residency: file Form N-400.

• For citizenship through U.S. citizen parents: file Form N-600.

All official forms are available on the USCIS website, along with detailed instructions and a list of required documents.

2. Naturalization application (Form N-400)

Applies to individuals seeking citizenship through permanent residency and residence in the U.S.

You will need to prepare:

• Completed and signed Form N-400.

• Fee as announced by USCIS at the time of filing.

• Copy of Green Card.

• Marriage certificate (if applying under spouse category).

• Birth certificate (if needed to verify information).

• Military records (if applicable).

• Photos meeting technical requirements.

The mailing address for your application depends on your place of residence and special circumstances such as military service.

3. Citizenship application through parents (Form N-600)

Applies when you believe you already have U.S. citizenship through your parent(s).

The application typically includes:

• Form N-600.

• Proof of parent(s) being U.S. citizens at the time of your birth.

• Birth certificate showing parent-child relationship.

• Documents proving parent(s)' residency time in the U.S.

• Adoption papers (if applicable).

Some cases may have reduced or waived fees, for example, children of U.S. military personnel.

4. Double-check before submitting your application

Before submitting your U.S. citizenship application, you should:

1. Cross-reference the document checklist for the correct category.

2. Check signatures, dates, and personal information.

3. Keep copies of all submitted documents.

4. Monitor for biometrics notices and interview schedules after submission.

Minor errors can cause your application to be returned and delay processing by several months.

Step 6: Awaiting USCIS Response After Filing

1. Receive application receipt notice

Typically within 1–2 months after filing:

• USCIS will send a receipt notice acknowledging your application.

• This notice contains a receipt number.

• You can use this number to check your case status online.

If you haven't received a notice after a reasonable time, you should recheck the payment status of the fee and your mailing address.

2. Biometrics (Fingerprint) Appointment Letter

A few months after submitting your application, you will usually receive:

• An appointment letter to visit a USCIS center for fingerprinting.

• The letter will specify the date, time, and location.

When you go, you need to bring:

• The original appointment letter.

• Your Green Card.

• A photo ID (driver's license or passport).

Biometrics are used for background checks and identity verification, and are a mandatory step in the process of applying for U.S. citizenship.

3. May be asked to provide additional documents

In some cases, USCIS will send a Request for Evidence (RFE).

This may happen if:

• Documents are missing from the application.

• Clarification is needed on residency, tax, or marital information.

• There are discrepancies in immigration data.

You must respond on time and submit all requested documents. Late submissions may lead to your application being denied.

Practical experience during the waiting period

When pursuing dual U.S.-Canada citizenship, you should:

1. Track your application periodically using the receipt number.

2. Update your address if you change your place of residence.

3. Carefully keep all correspondence from USCIS.

The processing waiting period is a normal part of the process. Being proactive and prepared for the next steps will help you move closer to your goal of obtaining U.S. citizenship smoothly and safely.

Step 7: Wait for your interview and naturalization test schedule

1. Receive an interview and naturalization test invitation letter

USCIS will send an invitation letter detailing:

• The interview location.

• Specific date and time.

• A list of required documents to bring.

At the appointment, you will:

• Answer questions about your personal application.

• Take an English language test (reading, writing, speaking).

• Take a civics test about U.S. history and government.

This is a crucial step before being sworn in as a citizen.

2. If you need to reschedule your interview

If you cannot attend your scheduled appointment:

• You must submit a written request to reschedule as instructed in the invitation letter.

• You should not fail to appear without prior notification.

Unjustified absence may lead to your application being closed or prolong the processing time.

3. If waiting too long for an invitation letter

Typically, the waiting time for a test schedule can extend for several months depending on the region.

If after approximately 7 months from the application date you have not received a notice:

• You should check your application status online.

• You can contact the USCIS customer service center to verify the processing status.

Proactive monitoring helps prevent missing important notifications.

4. Thoroughly prepare for the naturalization test

To increase your chances of passing on the first attempt, you should:

• Study the 100 civics questions published by USCIS.

• Practice reading and writing basic English sentences.

• Review all information declared in Form N-400 to answer consistently.

USCIS provides official study materials on its website, and there are also many test preparation classes specifically for naturalization applicants.

Practical experience

The naturalization interview is not intended to "fail" applicants, but to confirm that you meet the requirements to become a U.S. citizen. If your application is transparent, you have resided lawfully, and you are well-prepared, your chances of passing are very high.

Step 8: Take the U.S. naturalization test and interview

1. Only 2 chances to pass the test

You are allowed to take the test a maximum of 2 times for the same application.

• If you fail both times, you must submit a new application from the beginning.

• If you do not attend the interview and do not provide prior notice, USCIS will close your application.

• You have a maximum of 1 year to request to reopen your application; otherwise, it will be completely denied.

Therefore, absolutely do not miss your appointment.

2. What does the interview cover?

The interview usually follows this order:

• The USCIS officer will reconfirm the information in Form N-400 and conduct a background check.

• You must answer truthfully and consistently with the information provided in your application.

This exchange also counts as an assessment of your English speaking skills.

3. English language proficiency test

The English test consists of 3 parts:

• Reading: You must read aloud 1 of 3 English sentences provided by the officer.

• Writing: You must write down 1 of 3 English sentences read aloud to you.

• Speaking: Assessed through your interview responses.

USCIS provides an official vocabulary list for test preparation.

4. Civics Test

You will:

• Be asked 10 questions about U.S. history and government.

• Answer at least 6 questions correctly to pass.

Questions are randomly selected from the official 100 questions published in advance by USCIS.

Studying this specific set of questions significantly increases your chances of passing.

5. Receive results immediately after the interview

After the test and interview, you will:

• Be informed if you passed, failed, or need to provide additional information.

• If you pass, you will await the schedule for the Oath of Allegiance ceremony.

If you are asked to retake a section you did not pass, you will be scheduled for a retest within a specified timeframe.

Practical tips for passing on the first attempt

Before your U.S. citizenship interview, you should:

1. Thoroughly review the 100 official civics questions.

2. Review all information in your N-400 application.

3. Practice reading and writing basic English sentences multiple times.

4. Stay calm and answer concisely and truthfully.

This is not a trick test, but a step to confirm your readiness to become a U.S. citizen. If you prepare thoroughly, the success rate is very high.

Step 9: Oath Ceremony and Receiving U.S. Citizenship

1. Attend the naturalization oath ceremony

Once your application is approved:

• You will receive a letter notifying you of the date, time, and location of the ceremony.

• In some cases, the oath may be administered on the same day as the interview, but most often it will be scheduled for a later date.

At the ceremony, you will recite the Oath of Allegiance and officially become a U.S. citizen.

2. Complete Form N-445 before the ceremony

Before the oath ceremony date, you must complete Form N-445.

This form:

• Confirms details about the ceremony.

• Asks if your personal circumstances have changed (marriage, divorce, address change, etc.).

• Lists the documents you need to bring.

Upon arrival at the ceremony, a USCIS officer will review the information you provided on Form N-445.

3. Surrender your Green Card

At the ceremony:

• You must surrender your Permanent Resident Card (Green Card).

• After this point, you are no longer a permanent resident but a U.S. citizen.

This is the official legal transition.

4. Receive your Certificate of Naturalization

After taking the oath, you will be issued a Certificate of Naturalization.

You need to:

• Carefully check your name, date of birth, and personal information.

• Report any errors immediately for correction.

This certificate is legal proof that you have obtained U.S. citizenship.

5. Things to do after becoming a citizen

After the ceremony, you can:

• Apply for a U.S. passport.

• Register to vote.

• Update your citizenship status with the Social Security Administration (SSA).

These are important steps to complete the rights and responsibilities of a citizen.

Practical perspective for dual citizenship planning

If your goal is dual U.S.-Canada citizenship, the oath ceremony marks the completion of half of your strategy. From this point, you officially have full U.S. citizen rights, while still being able to maintain Canadian citizenship if you meet the laws of both countries.

Part 3: Guide to Obtaining Canadian Citizenship for Vietnamese Citizens

Step 1: How to check if you already have Canadian citizenship

Before starting the process on your journey to obtaining U.S. and Canadian citizenship, you should check if you already have Canadian citizenship. Many people are unaware that they are already Canadian citizens by law without needing to apply for new naturalization.

Official information and current regulations are managed by the Government of Canada.

1. Distinguishing between "proof of citizenship" and "naturalization application"

• Applying for Proof of Citizenship is to confirm you are already a citizen.

• Applying for naturalization is a process for permanent residents who are not yet citizens.

If you are eligible for citizenship by law, you will be issued a Certificate of Citizenship without needing to pass a test or meet additional residency requirements.

2. You may already be a Canadian citizen if you fall into one of the following categories:

• Born in Canada (with some special exceptions, such as children of diplomats).

• Naturalized by a parent or legal guardian when you were a minor.

• Born outside Canada after April 17, 2009, and at the time of birth, at least one parent was:

  • Born in Canada, or

  • Had become a Canadian citizen before your birth.

Many people born abroad automatically acquire citizenship by descent.

3. Notes on the 2009 and 2015 law changes

The Canadian Citizenship Act underwent significant amendments in 2009 and 2015.

These changes affected:

• Citizenship rules based on parentage.

• Reacquisition of citizenship for certain groups who had lost it due to old regulations.

• Limitations on transmitting citizenship to generations born outside Canada.

If you were born during these transitional periods, you need to carefully check the regulations applicable to your birth year.

4. How to check citizenship status

You can:

1. Apply for Proof of Citizenship.

2. Provide your birth certificate, parents' documents, and other relevant evidence.

3. Wait for immigration authorities to verify and issue a Certificate of Citizenship if eligible.

This is a recommended step before starting the process of applying for Canadian citizenship as a permanent resident.

Strategic Perspective

In a long-term plan for dual US-Canada citizenship, checking your citizenship status beforehand can save you many years of waiting. Some people think they need to naturalize, but they were already citizens by law.

Step 2: Canadian Citizenship Requirements

1. Be 18 years old (or apply on behalf of a child)

• Applicants must be 18 years of age or older.

• If applying for a child under 18: a parent or legal guardian must submit the application.

• The child must be a permanent resident, and at least one parent must be a Canadian citizen or applying for citizenship at the same time.

2. Hold valid permanent resident status (PR)

• Must be a permanent resident of Canada.

• Not under investigation for immigration fraud.

• No deportation order.

• Not in violation of residency obligations.

You are not required to have a valid PR card to apply, but your PR status must be valid.

3. Meet the physical presence requirement

This is the most important condition for Canadian citizenship.

• Physically present in Canada for at least 1,095 days (3 years).

• This period must fall within the 5 years immediately before the date of application.

Children under 18 and some specific government employees may be exempt from this condition.

4. Fulfill tax obligations

• Must have filed and fulfilled tax obligations for at least 3 of the 5 years immediately before the application date (if applicable).

• Tax records must be transparent and free of serious errors.

This factor is often overlooked but directly impacts the outcome of the application.

5. Commitment to reside in Canada

In your application, you must declare:

• Intention to reside in Canada.

• Or work abroad as a Crown servant.

• Or live with a family member who is a Crown servant.

This commitment demonstrates your genuine attachment to Canada.

6. Sufficient language ability (English or French)

You must demonstrate that you can:

• Listen and speak English or French at a basic conversational level.

• Participate in daily conversations.

• Understand simple instructions and answer basic questions.

The immigration officer will directly assess your language skills.

7. Pass the citizenship knowledge test

You will be tested on:

• Canadian history.

• Values and political institutions.

• Symbols and government system.

Typically, it is a written test, but it may be oral in some cases.

8. Not subject to prohibitions

You will not be eligible if:

• You are facing criminal charges.

• You are on parole or probation.

• You have recently been convicted and have not completed the waiting period as per law.

• You are in the process of appealing a criminal case.

A "clean" legal history is a crucial factor when considering Canadian citizenship.

Practical perspective for dual citizenship planning

If you are building a dual US-Canada citizenship strategy, Canada generally offers a more predictable and clear timeline. However, this is only true if you effectively manage:

1. The number of days of physical presence.

2. Complete tax records.

3. A clear legal history.

Checking the requirements before applying will help you avoid unnecessary delays, fees, and prolonged waiting times in your long-term immigration journey.

Step 3: Canadian Citizenship Application Package

1. Select the correct application package by applicant type

There are 3 types of application packages:

• Adults (18 years and older).

• Minors (under 18 years).

• Canadian Armed Forces members (18 years and older).

Choosing the wrong application package can lead to the application being returned immediately.

2. Read instructions carefully before filling out the form

The Canadian immigration website provides:

• Detailed instructions on how to fill out each section of the form.

• Updated fee information.

• A list of mandatory documents to submit.

Do not fill out based on guesswork. Each section has specific requirements regarding residency time, tax filing, and personal information.

3. Prepare and make copies of all documents

You should:

• Photocopy all documents before sending them.

• Keep copies of all signed forms.

• Prepare original documents to bring with you if requested for a test or interview.

Official instructions will specify which documents need to be submitted as copies and which must be presented as originals.

4. Ensure the application package is complete before submission

When applying for Canadian citizenship, you must include:

• All fully signed forms.

• Documents proving residency time.

• Tax documents (if applicable).

• The correct fee as per regulations.

• The correct postal code for all declared addresses, including foreign addresses.

Missing a small detail like a signature, incorrect fee, or incomplete postal code can lead to the application being returned and delay the process by many months.

Practical experience

In a dual US-Canada citizenship strategy, Canadian applications are often returned due to technical errors rather than ineligibility. Therefore:

1. Check the checklist at least twice before submitting.

2. Ensure information matches tax records and PR records.

3. Keep personal records organized and ready for supplementary requests.

Thorough preparation in the application submission step will help the processing go smoothly and significantly shorten the waiting time for naturalization.

Step 4: Preparing for the Canadian Citizenship Test

1. Who must take the citizenship test?

• Individuals aged 14 to 64 at the time of application are required to take the test.

• Minors may be accompanied by a parent or legal guardian to the test or interview.

• However, parents are not allowed to assist with answers during the test.

Therefore, thorough preparation is needed before receiving the appointment notice.

2. Official study material: Discover Canada

The most important study resource is the "Discover Canada" book published by the government.

You should:

• Download the official PDF or eBook.

• Listen to the audio version if you want to practice listening simultaneously.

• Read the entire content carefully at least 2–3 times.

Most exam questions are directly based on this document.

3. Knowledge content to master

The exam focuses on:

• The rights, freedoms, and responsibilities of Canadian citizens.

• Canada's democratic system and how to participate in society.

• Canadian political and military history.

• Social and cultural history, and national symbols.

• The physical and political geography of Canada.

Understanding the concepts rather than memorizing will boost your confidence during the exam.

4. Preparing for the interview and language assessment

In addition to the written (or computer-based) exam, you may be:

• Interviewed directly by an immigration officer.

• Assessed for English or French listening and speaking abilities.

You should:

• Practice answering simple questions about yourself, your job, and your residence history.

• Practice daily conversations to communicate more naturally.

Practical tips to pass on the first attempt

To increase your chances of passing the Canadian citizenship test, you should:

1. Complete the practice tests multiple times.

2. Take notes on important historical milestones and events.

3. Practice speaking concisely and clearly when answering interview questions.

The exam is not designed to trick you, but to confirm your understanding of the country you are about to become a citizen of. Thorough preparation will help you take a solid step forward in your long-term US-Canada dual citizenship plan.

Step 5: Attend the Canadian Citizenship Test

1. Receive the invitation letter and reschedule if necessary

The invitation letter will specify:

• The date, time, and location of the test.

• Instructions on required documents to bring.

If you cannot attend as scheduled:

• You must contact the Call Centre to request a reschedule.

• If you are absent without notification, your application may be closed.

Proactively contacting them early will prevent delays in your application.

2. Documents to bring

When attending the test, you should bring:

• Originals of all documents submitted with your application.

• All passports or travel documents from the past 4 years.

• Permanent Resident (PR) card, if applicable.

The officer may compare your entry and exit history with the number of days you declared residence.

3. Written or oral test?

The test format depends on your application:

• Most applicants take a written (or computer-based) test.

• If you have difficulty reading and writing English or French, you may be given an oral interview with an officer.

The content will still revolve around the knowledge in the Discover Canada document.

4. Receive results immediately after the test

Typically, you will know the results immediately after the test:

• If you pass: you will be notified of the date for your citizenship ceremony.

• The ceremony usually takes place within 6 months of the test date.

If you do not pass:

• You may be scheduled for a retest or an additional interview.

• In some cases, you may need to submit a new application.

Practical tips to avoid risks

To increase your chances of passing the Canadian citizenship test on the first attempt, you should:

1. Thoroughly review the Discover Canada content.

2. Reconfirm your residency days before the test.

3. Bring all old passports to avoid suspicion about time spent abroad.

The test is a step to confirm your understanding of the country you are about to become a citizen of. Thorough preparation will help you complete another important stage in your long-term US-Canada dual citizenship plan.

Step 6: Attend the Canadian Citizenship Ceremony

1. Who must attend the ceremony?

• All applicants 14 years of age or older must attend in person.

• This is a mandatory requirement to receive your Certificate of Citizenship.

Failure to attend without a valid reason may result in your application being put on hold.

2. Documents to bring

When attending the ceremony, you must bring:

• All original immigration documents.

• Permanent Resident (PR) Card, if applicable.

• Record of Landing (for those who became permanent residents before June 28, 2002).

The officer will collect or verify certain documents depending on your application status.

3. What happens at the ceremony?

During the ceremony:

• You will recite the Oath of Citizenship.

• You will pledge to respect the laws and values of Canada.

• You will receive your Certificate of Citizenship.

From the moment you complete the oath, you officially become a Canadian citizen.

4. What to do after the citizenship ceremony?

After obtaining Canadian citizenship, you can:

• Apply for a Canadian passport.

• Update your personal information with government agencies if necessary.

• Exercise all your rights and responsibilities as a citizen.

A practical perspective for dual citizenship planning

If you are aiming for US-Canada dual citizenship, the citizenship ceremony in Canada marks the completion of half or all of your immigration strategy. From this point, you have full Canadian citizenship rights, while still being able to maintain US citizenship if you meet the laws of both countries.

Important considerations for US-Canada dual citizenship

Once you have completed the journey of how to get US and Canadian citizenship and hold US-Canada dual citizenship, you gain many rights, but also need to understand the legal responsibilities that come with it.

1. You should carry both passports when traveling

When entering or exiting the US or Canada:

• You should carry both your US and Canadian passports.

• Use the correct passport as required by each country upon entry.

However, having two passports may lead to more thorough checks by security personnel, so you need to declare truthfully and consistently.

2. Marriage does not automatically grant citizenship

• Marrying a US or Canadian citizen does not automatically grant you citizenship.

• You must still meet all residency requirements, pass tests, and submit applications according to the law.

This is a common misconception when learning how to obtain US citizenship or Canadian citizenship.

3. Check obligations in the other country

Before maintaining dual citizenship, you should verify:

• Whether there are obligations to declare and pay taxes.

• Whether military service is required (if applicable).

• Whether there is a minimum residency requirement to maintain citizenship.

Laws vary by country and change over time.

4. Benefits of dual citizenship

Holding US-Canada dual citizenship offers significant advantages:

• Access to the education and healthcare systems of both countries.

• Freedom to work and live in two leading developed countries.

• Increased international travel opportunities with two strong passports.

This is why many families build long-term citizenship strategies.

5. Laws can change over time

• Some countries require actual residency to maintain voting rights.

• You may need to appear periodically in the country to avoid losing legal status.

Therefore, staying updated on laws is essential.

6. Certificate of Citizenship does not replace a passport

Canadian citizens can apply for a Certificate of Canadian Citizenship, but:

• This is not a travel document.

• It cannot be used instead of a Canadian passport when traveling abroad.

To travel internationally, you must still have a valid passport.

7. Legal risks when laws of both countries conflict

Dual citizenship can be complex if:

• The two countries have conflicting legal regulations.

• You need consular assistance in a third country.

In some cases, one country may not recognize the intervention of the other if you are on their territory.

8. You must comply with the laws of both countries

As a citizen of two countries, you:

• Must comply with the laws of both the US and Canada.

• Cannot claim "I am a citizen of the other country" to avoid obligations.

A practical perspective for long-term strategy

Dual citizenship is a strategic asset if you manage your legal and financial obligations well. Before deciding to pursue how to get US and Canadian citizenship, consider not only the benefits but also the long-term responsibilities involved.
