Citizenship Through Parents - Requirements

U.S. citizenship is one of the most valuable statuses in the world. It offers voting rights, protection from deportation, and the ability to travel with a U.S. passport. Many people assume they have to go through the long process of naturalization to become a citizen. However, some people are already citizens and don’t even know it.

This concept is often called “citizenship through parents.” Depending on when you were born and the status of your parents, you might have acquired citizenship at birth or derived it automatically when your parents became citizens.

Understanding the specific requirements for citizenship through parents can be confusing. The rules depend heavily on dates, residency, and marital status. If you do not meet the automatic requirements, you may still need to file a standard application for naturalization.

This guide will break down the complex rules into simple terms. We will cover who qualifies, which forms to use, and what to do if you are already an adult.

Two Main Paths to Citizenship Through Parents

When we talk about getting citizenship through parents, we are usually talking about two different scenarios. It is vital to know which one applies to you because the evidence you need to show the government is different for each.

1. Acquisition at Birth

This applies if you were born outside of the United States, but at least one of your parents was a U.S. citizen at the time of your birth. In this case, you may have “acquired” citizenship the moment you were born. You are not “becoming” a citizen; you are technically already one.

2. Derivation After Birth

This applies if you were born outside the U.S. to parents who were not citizens at the time of your birth. Later, you and your family moved to the U.S. as permanent residents (Green Card holders), and your parents became naturalized U.S. citizens. Under certain conditions, their citizenship extends to you automatically.

Path 1: Born Abroad to U.S. Citizen Parents

If you were born outside the United States, you might be a citizen if your mother, father, or both were citizens when you were born.

Requirements for Two U.S. Citizen Parents

If both of your parents were U.S. citizens when you were born, the requirements are fairly simple:

• Both parents must have been U.S. citizens at the time of your birth.
• At least one parent must have had a residence in the U.S. or its territories prior to your birth.

Requirements for One U.S. Citizen Parent

If only one parent was a U.S. citizen when you were born (and the other was a foreign national), the rules are stricter. The U.S. citizen parent must meet “physical presence” requirements.

For births on or after November 14, 1986:

• The U.S. citizen parent must have been physically present in the U.S. for a total of 5 years before you were born.
• At least 2 of those 5 years must have been after the parent turned 14 years old.

Path 2: The Child Citizenship Act of 2000 (Derivation)

This is the most common path for families immigrating together. The Child Citizenship Act (CCA) of 2000 made it much easier for children to gain citizenship. This law went into effect on February 27, 2001.

If you are the child of a U.S. citizen, you automatically become a citizen if you meet all of the following requirements at the same time:

1. Under 18: You are under 18 years of age.
2. Parent is a Citizen: At least one parent is a U.S. citizen (by birth or naturalization).
3. Legal Custody: The U.S. citizen parent has legal and physical custody of you.
4. Green Card Holder: You reside in the United States in the legal and physical custody of the citizen parent pursuant to a lawful admission for permanent residence. This means you must have your Green Card.

If you satisfy all these conditions simultaneously before your 18th birthday, you are automatically a citizen. You do not need to take a test. You do not need to go to an interview to become a citizen. You simply need to apply for proof of your status.

What If I Am Over 18?

This is the most common question we receive. Many people realize their parents became citizens years ago, but the child (now an adult) never filed any paperwork.

If you are currently over 18:

• Did you meet the requirements BEFORE you turned 18? If your parent naturalized when you were 15, and you had your Green Card and lived with them, you became a citizen automatically at age 15. You are a citizen today. You just need to file paperwork to prove it (Form N-600).
• Did your parent naturalize AFTER you turned 18? If your parent became a citizen when you were 19, you did not derive citizenship. You are not a U.S. citizen yet. You must apply for naturalization on your own using Form N-400.

Proving Your Status: Form N-600 vs. Passport

If you meet the requirements for automatic citizenship (either born abroad to citizens or derived through parents), you need proof. You have two main options.

Option A: U.S. Passport

Applying for a passport is often the fastest and cheapest way to prove citizenship. You apply through the Department of State. You will need to submit evidence of your parent’s citizenship, your birth certificate, and your Green Card (if applicable).

Option B: Form N-600 (Certificate of Citizenship)

This form is filed with USCIS. It provides you with a Certificate of Citizenship. This is a very strong document that never expires. It is highly recommended to have this certificate even if you already have a passport, as it serves as primary evidence of your status for the rest of your life.

Note: The N-600 is not a request to become a citizen. It is a request for the government to recognize that you are already a citizen.

When You Must File Form N-400

If you do not qualify for automatic citizenship through your parents, you must go through the standard naturalization process. This requires filing Form N-400, Application for Naturalization.

You likely need to file Form N-400 if:

1. You are over 18 years old.
2. Your parents did not naturalize before your 18th birthday.
3. Or, you did not have your Green Card or live in the U.S. before your 18th birthday.

N-400 Requirements

To file Form N-400 based on your own status, you generally must:

• Be at least 18 years old.
• Have been a Permanent Resident (Green Card holder) for at least 5 years (or 3 years if married to a U.S. citizen).
• Demonstrate continuous residence and physical presence in the U.S.
• Be able to read, write, and speak basic English.
• Pass a civics test (history and government).
• Demonstrate good moral character.

Processing Time and Cost

• Filing Fee: The current government filing fee for Form N-400 is $760.
• Timeline: The process typically takes between 8 and 14 months, depending on your local USCIS field office.

Required Documents

Whether you are filing Form N-600 (to prove status) or N-400 (to gain status), documentation is key. Missing documents can lead to long delays or rejections.

For Citizenship Through Parents (N-600)

If claiming automatic citizenship, you typically need:

• Your birth certificate.
• Your parent’s birth certificate.
• Your parent’s Certificate of Naturalization (if they were not born in the U.S.).
• Your parents’ marriage certificate (and divorce decrees from prior marriages).
• Proof of your parent’s physical presence in the U.S. (school records, tax transcripts, employment records).
• Your Green Card (Permanent Resident Card).
• Evidence that you lived in the legal and physical custody of your U.S. citizen parent (lease agreements, school records).

For Naturalization (N-400)

If applying on your own, you need:

• A copy of your Green Card.
• Marriage certificate (if applying under the 3-year rule).
• Proof of travel history for the last 5 years.
• Tax returns.
• Information about your children and spouse.

Common Mistakes to Avoid

The rules for citizenship through parents are strict. Here are common pitfalls families encounter.

1. Waiting Too Long

The most critical mistake is waiting until the child turns 18. Once the child turns 18, the window for automatic derivation closes forever. The child must then wait to qualify for N-400 naturalization on their own, which costs money and requires passing exams.

2. Assuming a Step-Parent Counts

You cannot derive citizenship automatically from a step-parent unless the step-parent legally adopted you before your 16th birthday (and you met all other residency requirements). Simply living with a U.S. citizen step-parent does not grant citizenship.

3. Not Having a Green Card

You generally cannot derive citizenship if you are in the U.S. on a visitor visa or undocumented status. You must be a Lawful Permanent Resident (Green Card holder) living in the U.S. to benefit from the Child Citizenship Act.

4. Filing the Wrong Form

Filing Form N-400 when you are already a citizen (and should have filed N-600) can cause confusion. Conversely, filing N-600 when you don’t actually meet the requirements is a waste of money because the filing fee is usually non-refundable.

Frequently Asked Questions

We have compiled answers to the most common questions about citizenship through parents requirements.

Can I get US citizenship if my parents are citizens?

Yes, you may acquire citizenship at birth if born abroad to U.S. citizen parents, or derive it automatically if your parents naturalize before you turn 18. If you are over 18, you must apply for naturalization on your own using Form N-400.

What is the age limit for citizenship through parents?

To derive citizenship automatically through a naturalized parent, you must be under 18 years old, unmarried, and living in the U.S. as a permanent resident. If you are already over 18, you cannot derive citizenship automatically and must apply for naturalization.

Which form do I file for citizenship through parents?

If you are already a citizen through your parents, you file Form N-600 to get a Certificate of Citizenship. If you are over 18 and applying for naturalization yourself, you must file Form N-400.

Do I have to take a test for citizenship through parents?

If you qualify for automatic citizenship (Form N-600), you generally do not take a Civics or English test. However, if you are over 18 and filing Form N-400, you must pass both the English and Civics exams.

How much does it cost to apply for citizenship?

The government filing fee for a standard naturalization application (Form N-400) is $760. If you hire a service like Greenbroad to prepare your application package, there is an additional flat fee of $749.

Conclusion

Securing U.S. citizenship is a milestone that provides security and opportunity. Whether you are claiming citizenship you acquired at birth or applying for naturalization as an adult, it is important to get the details right.

If you are a parent, keep a close eye on the “under 18” requirement. Getting your child their Green Card and finalizing your own naturalization before their 18th birthday can save them years of waiting and paperwork later in life.

If you are an adult ready to apply for naturalization on your own, the N-400 application is your path forward. It requires preparation, but the reward is worth the effort.
