This database contains information pertaining to Naturalization Petitions for the Southern District of California for the years of 1887-1940.
Typing a name into the search box will lead you to all parts of a petitioner’s records. Occasionally extra documents are filed separately and are not necessarily included with the petition and declaration for one person. It is also possible to locate an oath of allegiance or arrival record in this manner. After 1930, many declarations of intention will include a photo of the immigrant.
