Child Citizenship Act

How to Get a Certificate of Citizenship for Your Child

Citizenship for children

The Child Citizenship Act (CCA) which became effective on February 27, 2001, amends the Immigration and Nationality Act (INA) to provide U.S. citizenship to certain foreign-born children—including adopted children—of U.S. citizens. In general, the Child Citizenship Act provides that children who are less than 18 years of age and have at least one parent who is a U.S. citizen whether by birth or naturalization-will benefit from this new law. Under the  Child Citizenship Act, qualifying children who immigrate to the United States with a U.S. citizen parent automatically acquire U.S. citizenship; children who live abroad acquire citizenship by application.

USCIS  will work with Congress, the adoption community and other stakeholders to re-engineer and streamline the current process for obtaining a Certificate of Citizenship for a child. However, if you wish to obtain a Certificate of Citizenship for your child at this time, the process is explained below. In addition, you may obtain a passport for your child from the Department of State.

What forms do I file and what are the fees?

  • If you are want a Certificate of Citizenship for a biological child, you file Form N-600, Application for Certificate of Citizenship with a $600 fee ; or
  •  If you want a Certificate of Citizenship for an adopted child, you file Form N-643, Application for Certificate of Citizenship in Behalf of an Adopted Child with a $650 fee; or
  • If you are applying for a Certificate of Citizenship for a biological or adopted child who currently lives outside the United States, you may also need to file Form N-600/N-643, Supplement A, Application for Acquisition of Citizenship Through a Grandparent, with the Form N-600 or Form N-643. There is no additional fee for this supplement.

I am filing for a child who lives abroad. How do I know if I need to file the Form N-600/N-643, Supplement A?


Under the Child Citizenship Act, the U.S. citizen parent of a child living abroad must have five years of physical presence in the United States or its outlying possessions with at least two years occurring after age 14, in order to apply for citizenship on behalf of the child. If you cannot meet this requirement, the law allows you to rely on the physical presence of your citizen parent to apply for citizenship. If you are relying on the physical presence of your U.S. citizen parent, you must file the Form N-600/N-643, Supplement A.


Where Should I File the Forms?


If you are filing for a child who lives in the United States, file the Form N-600 or N-643 at the USCIS district office or suboffice in the United States with jurisdiction over your place of residence.


If filing for a child, who lives abroad, you may file the Form N-600 or N-643 at any USCIS district office or suboffice in the United States. You and your child will need to travel to the United States to complete this application process.
