As U.S. citizen parent(s), you should report your child's birth abroad as soon as possible to the nearest U.S. embassy or 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 of a Citizen of the United States of America , Form FS-240. This document, know as the Consular Report of Birth Abroad , is a basic United States citizenship document. An original FS-240 document will be given to you at the time registration is approved.
A Consular Report of Birth can only be prepared at a U.S. embassy or consulate. It cannot be prepared if the child has been brought back into the United States, or, if the person is 18 years of age or older at the time the application is made.
