What happens if a U.S. citizen has a baby in Mexico?

If you are a U.S. citizen (or non-citizen national) and have a child overseas, you should report their birth at the nearest U.S. embassy or consulate as soon as possible so that a Consular Report of Birth Abroad (CRBA) can be issued as an official record of the child’s claim to U.S. citizenship or nationality.
