Naturalization and Citizenship Records
All naturalization records produced by San Mateo County Courts are held by the San Mateo County Recorders Office. This appears to be a complete set of all the Declarations of Intention to become a citizen and Petitions for the entire time the local courts handled naturalizations. The last record is from the year 1983. The earliest records are in an envelope file, and many records have Declarations attached which were filed elsewhere.

The San Mateo County Genealogical Society has indexed these volumes through 1945.

SMC Naturalization Indexes


 * Prior to 1906
 * 1907-1925
 * 1926-1945
 * post 1945

There are references to early naturalizations in the Court Docket books which are located in the San Mateo County Historical Society Archives. All names found in these volumes are also found in the Records office records.

The Naturalizations for Camp Fremont are contained in volumes dated May 1917 to March 1918. The special military naturalization required no Declaration of Intention, therefore the complete record will be contained in one volume. Naturalized soldiers were from all over the United States. Originals are located in the SMC Recorder's Office offsite storage facility. SMCGS has also indexed those volumes.

Camp Fremont Naturalization Index Naturalizations filed by San Mateo County in the California Northern District court are located at the National Archives in San Bruno.

SMCGS also transcribed a card file of naturalized voters, which is also located in the Recorders Office.
