As U.S. citizen parent(s), you should report your child’s birth abroad as soon as possible to the U.S. Consulate to establish an official record of the child’s claim to U.S. citizenship at birth. The official record will be the Consular Report of Birth Abroad, Form FS-240 which is a basic United States citizenship document.
Consular Report of Birth Abroad (CRBA)
A Consular Report of Birth (CRBA) is evidence of United States citizenship, issued to a child born abroad to a U.S. citizen parent or parents who meet the requirements for transmitting citizenship under the Immigration and Nationality Act (INA).
CRBA applications must be made before the child’s 18th birthday, and we recommend that the parents apply for the CRBA as soon as possible after the child’s birth. For applicants older than age 18 who have never been issued a CRBA, please refer to Possible Derivative Claim to U.S. Citizenship. Anyone who has a claim to U.S. citizenship must be in posession of a valid U.S passport to enter and exit the United States, even if they have citizenship of another country, as well.
