California, Northern U.S. District Court Naturalization Index - FamilySearch Historical Records

What is in This Collection?
This collection is a card index to naturalization records in the circuit and district courts of California for the years 1852 to 1989. The cards are arranged alphabetically by surname.

The index is very accurate and the information that was current at the time of naturalization was usually reliable. However, there was always a chance for misinformation. Errors may have occurred because of the informant’s lack of knowledge or because of transcription errors or other circumstances.

The following collections are covered by this index: ''' US District Court. Southern (San Francisco) Division. Northern District.'''
 * Duplicate Certificates of Citizenship, 1852-1906. NAID 2524822
 * Naturalization Depositions, 1907-1963. NAID 2602672
 * Applications for Repatriation, 1936-1969.NAID 2601974
 * Petitions for Naturalization Transferred from Other Courts, 9/21/1952-8/23/1990 NAID 627696
 * Petitions for Naturalization,10/23/1903-9/17/1991 NAID 605234

The naturalization volumes vary in size and format. Prior to the late 1800s each document was usually handwritten on one page. From the late 1800s and on, printed forms were used. After 1906, many entries were typewritten. While there were various types of naturalization records, the Declaration of Intent and Naturalization Petition usually had the most complete genealogical information. The first naturalization act was passed in 1802. Immigrants to the United States were not required to apply for citizenship. Of those who did apply, many did not complete the requirements for citizenship. Naturalization to become a U.S. citizen was a two-part process: the Declaration of Intent to Naturalize, or First Papers, and the Naturalization Record (including the Naturalization Petition), or Final Papers. The First Papers were normally filed five years before the Final Papers because of the five-year residency requirement to become a citizen.

No centralized files existed before 1906. In 1906 federal forms replaced the various formats that had been used by the various courts. Copies were sent to the Immigration and Naturalization Service (INS), creating a central file for naturalization papers. The INS is now known as the U.S. Citizenship and Immigration Services (USCIS). Naturalization records are generally well preserved, but some records may have been lost to fire or other disasters. Naturalization is the process of granting citizenship privileges and responsibilities to foreign-born residents. California’s counties recorded naturalization procedures in the court records as legal proof of citizenship. The courts handling naturalizations changed several times so the card index was created as a way to quickly access specific records.

What Do I Do Next?
Indexes and transcriptions may not include all the data found in the original records. Look at the actual image of the record, if you can, to verify the information and to find additional information.

I Found the Person I Was Looking For, What Now?

 * Use the record to learn the place of origin and find vital records such as birth, baptism, and marriage
 * Use the information found in the record to find land and probate records
 * Use the record to see if other family members who may have immigrated
 * Look for the Declaration of Intent soon after the immigrant arrived. Then look for the naturalization petition five years later, when the residency requirement would have been met. Look for naturalization records in federal courts, then in state, county, or city courts. An individual may have filed the first and final papers in different courts and sometimes in a different state if the person moved. Immigrants who were younger than 18 when they arrived did not need to file a Declaration of Intent as part of the process

I Can’t Find the Person I’m Looking for, What Now?

 * If your ancestor does not have a common name, collect entries for every person who has the same surname. This list can help you find possible relatives
 * If you cannot locate your ancestor in the locality in which you believe they lived, then try searching records of a nearby town or county
 * Try different spellings of your ancestor’s name
 * Remember that sometimes individuals went by nicknames or alternated between using first and middle names.
 * Check other possible ports of entry
