SAN BRUNO — The National Archives at San Francisco on May 22 officially opened to the public over 40,000 case files on immigrants to the U.S., and dedicated its research room to the late U.S. Rep. Tom Lantos, who was a leading force in having these files re-designated as records of permanent historical value.

These immigration files, known as “Alien Files” (commonly referred to as “A-Files”), were transferred from U. S. Citizenship and Immigration Services (USCIS). They are among the first of millions of case files that will eventually be opened to the public.

During the opening, immigration records were viewed for the first time by descendants of early 20th-century Asian immigrants, and demonstrations were given on how to access the immigration files. Speakers included Tom Mills, chief operating officer, National Archives and Records Administration (NARA); Rep. Jackie Speier (D-San Mateo); Dominick Gentile, chief, Records Division, USCIS; Keaton and Chanteclaire Swett, grandchildren of Rep. Lantos; Jennie Lew and Jeanie Low, co-chairs, Save Our National Archives; Jeremy Frankel, director, San Francisco Bay Area Genealogical Society; and Rick Moss, director, African American Museum and Library of Oakland.

In 1940 the Immigration and Naturalization Service (INS), the predecessor of USCIS, started issuing Alien Registration Numbers to resident aliens. On April 1, 1944, INS began to assign these numbers to a new series of immigration case files called A-Files. A-Files are a genealogical wealth of information, containing documents such as photographs, personal correspondence, vital records, interview transcripts, and visa applications.

“The A-Files are a unique resource for family historians, especially the descendants of 20th-century immigrants,” said Archivist of the United States David S. Ferriero. “These records are rich with personal information that will illuminate the journeys of our ancestors — including my own family — and their paths to citizenship.”

A-Files are eligible for transfer to the National Archives 100 years after the birth of the subject of a file. These transfers to the National Archives ensure that these records will be saved in perpetuity and made available to the public for research.

The holdings of the National Archives at San Francisco will include many case files created at USCIS District Offices in San Francisco, Honolulu, Reno, Guam, American Samoa and the American Territories. The National Archives at Kansas City will maintain A-Files for all other INS district offices nationwide.

A-Files may be viewed in person by appointment or copies may be ordered for a fee. Researchers may contact National Archives staff at or (650) 238-3501 to search A-Files holdings for a particular file. Beginning Tuesday, May 29, an online database will be available through the National Archives at San Francisco website,

The National Archives at San Francisco is one of 22 facilities nationwide where the public can access federal archival records in person. Its holdings total over 60,000 cubic feet of historical records dating from the 1850s to the 1990s, created by more than 100 federal agencies and courts in Northern and Central California, Nevada (except for Clark County), Hawaii, Guam, American Samoa and the American Territories. The facility is located at 1000 Commodore Dr., San Bruno, CA 94066. and is open Monday through Friday from 7:30 a.m. to 4 p.m. (until 5:30 p.m. on Wednesdays). Appointments are strongly encouraged.

  1. Thank heaven Tom Lantos and his colleagues took action to preserve the A Files. They are certainly a vital component of American history. Without this primary source of data regarding the history of immigration and customs on the West coast, we would only be guessing about how immigrants we’re process and handled.the actions. Their actions or inactions had a tremendous impact of all groups who immigrated to America onthe West coast. B

    I personally found out the name of my great grandfather who cam to America in the 1880s in the A files.
