U.S. Citizenship for a Child Born Abroad

May 25, 2026 | Immigration Law

Obtaining U.S. citizenship for a child born abroad often involves applying for a Consular Report of Birth Abroad (CRBA) (Form FS-240). The application is typically filed at the nearest U.S. embassy or consulate before the child turns 18. In most cases, one parent must be a U.S. citizen and meet physical presence requirements in the United States before the child’s birth for citizenship to be transmitted.

Can a Child Born Abroad Obtain U.S. Citizenship?

Yes. If your child was born outside the United States, they may still obtain U.S. citizenship through a parent. In many cases, a child automatically acquires citizenship at birth if at least one parent was a U.S. citizen at the time of the child’s birth and that parent meets certain physical presence requirements in the United States before the birth.

Parents typically document this citizenship by applying for a Consular Report of Birth Abroad (CRBA) (Form FS-240) at the nearest U.S. embassy or U.S. consulate in the country where the child was born. This document serves as official proof that the child acquired U.S. citizenship at birth.

Because citizenship rules depend on several legal factors, including the parents’ citizenship status, marital status, and time spent living in the United States, understanding the requirements early can help families avoid delays when applying for citizenship documentation.

Important Requirements for Citizenship Through a Parent

  • U.S. Citizen Parent
    At least one parent must be a U.S. citizen at the time of the child’s birth for citizenship to be transmitted.
  • Physical Presence Requirement
    The U.S. citizen parent must have lived in the United States for a specific period before the child’s birth, as required by law.
  • Consular Report of Birth Abroad (CRBA)
    Parents usually apply for a CRBA (Form FS-240) through a U.S. embassy or consulate to document the child’s citizenship.
  • Application Timeline
    A CRBA application should generally be submitted before the child turns 18.
  • Alternative Proof of Citizenship
    If a CRBA was not issued, the child may later apply for a Certificate of Citizenship or a U.S. passport as proof of citizenship.

Understanding these requirements can help you determine whether your child may qualify for U.S. citizenship through a parent and what documents you may need.

Can You Get U.S. Citizenship Through Your Parents After Age 21?

Yes. In some situations, you may still obtain U.S. citizenship through your parents after age 21, particularly if citizenship was acquired at birth or automatically obtained before turning 18. Even if you are now an adult, you may already be considered a U.S. citizen if the legal requirements were met earlier.

However, automatic citizenship laws usually apply only when the requirements were satisfied before the child turned 18. Adults may still claim citizenship through citizenship by acquisition if a parent was a U.S. citizen at the time of birth and the required legal conditions were met.

Citizenship at Birth (Acquisition)

If you were born outside the United States and at least one parent was a U.S. citizen when you were born, you may have already acquired U.S. citizenship at birth.

In these situations, age does not usually prevent you from claiming citizenship later in life. However, you may need to show that your U.S. citizen parent met the required physical presence requirements in the United States before your birth.

To document citizenship, individuals often apply for a Certificate of Citizenship or a U.S. passport.

Automatic Citizenship Before Age 18 (Derivation)

Some individuals became U.S. citizens automatically before age 18 under laws such as the Child Citizenship Act.

This can apply if:

  • You were a lawful permanent resident (Green Card holder)

  • You were under 18

  • You were living in the legal and physical custody of a U.S. citizen parent

If these requirements were met when your parent naturalized, citizenship may have been automatically granted, even if you did not apply for proof at the time.

Family Immigration Options Through Parents

If you did not acquire or derive citizenship earlier, citizenship cannot usually be obtained automatically through your parents after age 21.

However, immigration laws still allow certain family-based immigration options. For example, a U.S. citizen parent may petition for their adult child to obtain lawful permanent residence, which could later lead to naturalization.

Important Documentation and Considerations

When determining whether citizenship may have been acquired earlier, several documents may be required. These may include:

  • Proof of the parents’ U.S. citizenship

  • The child’s birth certificate

  • Marriage records of the parents, when applicable

  • Evidence showing the parents’ physical presence in the United States

Rules may also vary depending on whether the parents were married and whether the child was born in or out of wedlock.

If you are unsure whether you may already qualify for citizenship through a parent, reviewing your family’s immigration history may help clarify your options. Additional information about citizenship documentation and procedures can also be found through the nearest U.S. Embassy or Consulate.

How a Child Born Abroad Can Obtain U.S. Citizenship

If your child was born outside the United States, there are several ways to confirm or obtain U.S. citizenship depending on the circumstances of the birth and the child’s status. In many cases, citizenship is documented through official records issued by the U.S. government.

Parents usually begin by registering the birth at a U.S. embassy or consulate and gathering the documents needed to confirm the child’s citizenship.

Consular Report of Birth Abroad (CRBA)

One of the most common documents used in these situations is a Consular Report of Birth Abroad (CRBA). This document is issued by the U.S. Department of State and confirms that a child born outside the United States acquired citizenship through a U.S. citizen parent.

Parents typically apply for a CRBA at the U.S. embassy or consulate in the country where the child was born. The application can usually be completed shortly after the birth.

What Are the Steps in Obtaining U.S. Citizenship for a Child Born Abroad

Several steps and documents may be required to confirm a child’s U.S. citizenship if born abroad. The following are common steps in this process.

Determine Eligibility

Before applying, parents must confirm that the child meets the legal requirements for citizenship. In many situations, the child must be under 18, and at least one parent must be a U.S. citizen who was physically present in the United States for a required period before the child’s birth.

File a Consular Report of Birth Abroad (CRBA)

Parents typically apply for a Consular Report of Birth Abroad (CRBA) to officially document the child’s citizenship.

Online Application (eCRBA)
Parents may create a MyTravelGov account to complete the CRBA application online, upload supporting documents, and pay the required fees.

In-Person Appointment
After submitting the application, parents must attend an appointment at the nearest U.S. embassy or consulate to submit documents and complete the process.

Required Documentation

Several documents are usually required when applying for citizenship documentation for a child born abroad. These may include:

  • The child’s foreign birth certificate

  • Evidence of the parents’ U.S. citizenship (such as a passport, birth certificate, or naturalization certificate)

  • The parents’ marriage certificate, if applicable

  • Evidence showing the parents’ physical presence in the United States, such as school records, tax returns, or employment records

In cases where a child was born out of wedlock to a U.S. citizen father, additional documentation, such as Form DS-5507, may be required to establish paternity and support.

Apply for a U.S. Passport

Parents may also apply for a U.S. passport for the child, often at the same time as the CRBA application. A passport can serve as additional proof of citizenship.

Alternative Option for Children in the United States

If the child is already a lawful permanent resident in the United States, parents may apply for citizenship documentation by filing Form N-600 (Application for Certificate of Citizenship) with U.S. Citizenship and Immigration Services (USCIS).

Completing these steps can help you document and confirm your child’s U.S. citizenship if they were born abroad. Requirements may vary depending on your family’s situation and your immigration history.

If you are unsure whether your child qualifies for citizenship, consulting an experienced citizenship lawyer may help clarify the process.

When Should You Consider Speaking With a Lawyer?

Not every situation involving U.S. citizenship for a child born abroad requires legal representation. However, guidance from an experienced immigration lawyer may be helpful in certain circumstances. You may consider speaking with a lawyer if eligibility rules are unclear or documentation requirements are difficult to meet.

Understanding how U.S. citizenship laws apply to your child’s situation can help you prepare citizenship documentation.
