Does my child automatically become a U.S. citizen when I naturalize?

Yes, if all conditions under INA Section 320 are met before the child turns 18: at least one parent is a U.S. citizen, the child is a lawful permanent resident, and the child resides in the U.S. in the legal and physical custody of the citizen parent. The child does not need to file a separate application to acquire citizenship.

How do I get proof of my child's citizenship after I naturalize?

You can file Form N-600, Application for Certificate of Citizenship, with USCIS to get an official Certificate of Citizenship. You can also apply for a U.S. passport for your child through the U.S. Department of State as proof of citizenship.

Can My Child Become a Citizen When I Naturalize?

Q: What if my child lives outside the United States?

Children residing outside the U.S. do not qualify under INA Section 320. They may qualify under INA Section 322, which has different requirements including a period of physical presence in the United States. Consult an immigration attorney for guidance on cases involving children abroad.

Yes. Under INA Section 320 (the Child Citizenship Act of 2000), your child can automatically become a U.S. citizen when you naturalize, as long as certain conditions are met before the child turns 18. According to USCIS, this happens by operation of law, meaning your child does not need to file a separate application to acquire citizenship.

What Is the Child Citizenship Act?

The Child Citizenship Act (CCA), which took effect on February 27, 2001, amended INA Section 320 to allow certain children of U.S. citizens to acquire citizenship automatically. Before this law, parents had to go through a separate naturalization process for their children. Now, if the conditions are met, citizenship is automatic.

Conditions That Must Be Met

According to USCIS, all of these conditions must be true before the child turns 18:

At least one parent is a U.S. citizen (by birth or through naturalization), including an adoptive parent
The child is under 18 years of age
The child is a lawful permanent resident (has a Green Card)
The child resides in the United States in the legal and physical custody of the citizen parent

If all four conditions are satisfied at the moment you take the Oath of Allegiance, your child becomes a citizen at that same moment.

Your Child Does Not Need to Apply Separately

This is one of the most common misunderstandings. Your child does not need to take a citizenship test, attend an interview, or file Form N-400. Citizenship under INA Section 320 is automatic once all the conditions are met. However, you will still need to get proof of your child's new status.

How to Get Proof of Your Child's Citizenship

Even though citizenship is automatic, you should obtain official documentation. You have two main options:

Certificate of Citizenship: File Form N-600, Application for Certificate of Citizenship, with USCIS. This is the most common way to get formal proof.
U.S. Passport: Apply for a U.S. passport for your child through the U.S. Department of State. A valid U.S. passport serves as proof of citizenship.

Having at least one of these documents is important for your child's future (school enrollment, employment, travel, and other situations that require proof of citizenship).

What If Your Child Lives Outside the United States?

Children living outside the U.S. do not meet the residency requirement under INA Section 320. However, they may qualify for citizenship under INA Section 322, which has different requirements, including a period of physical presence in the United States. This process requires filing a separate application before the child turns 18.

What About Children Who Are Already 18?

INA Section 320 only applies to children under 18. If your child was 18 or older when you naturalized, they do not automatically acquire citizenship through your naturalization. They would need to apply for naturalization on their own by filing Form N-400 and meeting all standard eligibility requirements.
