A synopsis of each historical records series follows.

Naturalization Certificate Files (C-Files) are copies of records relating to all U.S. naturalizations in Federal, State, county, or municipal courts, overseas military naturalizations, replacement of old law naturalization certificates, and the issuance of Certificates of Citizenship in derivative, repatriation, and resumption cases. Standard C-Files generally contain at least one application form (Declaration of Intention and/or Petition for Naturalization, or other application) and a duplicate certificate of naturalization or certificate of citizenship. Many files contain additional documents, including correspondence, affidavits, or other records. Only C-Files dating from 1929 onward include photographs.

Record Format: The majority of C-Files exist only on microfilm.

Alien Registration Forms (Form AR-2) are copies of approximately 5.5 million Alien Registration Forms completed by all noncitizens age 14 and older, residing in or entering the United States between August 1, 1940 and March 31, 1944. The two-page form called for the following information: name; name at arrival; other names used; street address; post-office address; date of birth; place of birth; citizenship; sex; marital status; race; height; weight; hair and eye color; date, place, vessel, and class of admission of last arrival in United States; date of first arrival in United States; number of years in United States; usual occupation; present occupation; name, address, and business of present employer; membership in clubs, organizations, or societies; dates and nature of military or naval service; whether citizenship papers filed, and if so date, place, and court for declaration or petition; number of relatives living in the United States; arrest record, including date, place, and disposition of each arrest; whether or not affiliated with a foreign government; signature, and fingerprint.

Visa Files are original arrival records of immigrants admitted for permanent residence under provisions of the Immigration Act of 1924. Visa forms contain all information normally found on a ship passenger list of the period, as well as the immigrant’s places of residence for 5 years prior to emigration, names of both the immigrant’s parents, and other data. Attached to the visa in most cases are birth records or affidavits. Also there may be attached other records such as: marriage, military, or police records.

Record Format: The Visa Files exist only in hard copy (textual) format.

Registry Files are records, which document the creation of immigrant arrival records for persons who entered the United States prior to July 1, 1924, and for whom no arrival record could later be found. Most files also include documents supporting the immigrant’s claims regarding arrival and residence (i.e., proofs of residence, receipts, and employment records).

Record Format: The Registry Files exist only in hard copy (textual) format.

Immigrant Files, (A-Files) are the individual alien case files, which became the official file for all immigration records created or consolidated since April 1, 1944. A-Numbers ranging up to approximately 6 million were issued to noncitizens within or entering the United States between 1940 and 1945. The 6 million and 7 million series of A-Numbers were issued between circa 1944 and May 1, 1951. Only A-File documents dated to May 1, 1951, are releasable under the Genealogy Program.
