What is a Consular Report of Birth Abroad?
Children born abroad to a U.S. citizen parent may have a claim to U.S. citizenship. A Consular Report of Birth Abroad (CRBA) is a certificate that serves as official evidence of U.S. citizenship issued to a child under the age of 18 who was born abroad to a U.S. citizen parent(s). It documents that the child acquired U.S. citizenship at birth.

Not all children born to U.S. citizen parents may have a claim to U.S. citizenship.
