Derivative Citizenship Files

The agency used the files to identify aliens who were issued an administrative certificate of citizenship because they derived or acquired citizenship by (a) birth abroad to citizen parents, (b) naturalization, while a minor, of one or both parents, and (c) marriage to a U.S. citizen prior to 1922. The agency produced statistical summary reports on derivative citizenships from these records.

This series cont ains records with the alien's name, Immigration and Naturalization Service issued identification number, year and country of birth, former nationality, reason for claim, and year and month the certificate was issued. This data comprises government records extracted from the Archival Research Catalog (ARC). See the ARC catalog entry for this series for more information on this data and how to order it.
