Certificate of Citizenship
Persons who were born abroad and later naturalized as U.S. citizens or who were born in a foreign country to a U.S. citizen (parent or parents) may apply for a certificate of citizenship pursuant to the provisions of Section 341 of the Immigration and Nationality Act. Application can be made for this document in the United States at the nearest office of the Immigration and Naturalization Service (INS). The INS will issue a certification of citizenship for the person if proof of citizenship is submitted and the person is within the United States. The decision whether to apply for a certificate of citizenship is optional; its possession is not mandatory because a valid U.S. passport or a Form FS-240 has the same evidentiary status.
