California, San Diego Naturalization Index - FamilySearch Historical Records

United States CaliforniaSan Diego County

What Is in the Collection?
This collection is a card index to naturalization records Superior Court for San Diego. The naturalization petitions, 4/20/1904-6/19/1956 are included in this index NAID 7560827. The cards are arranged alphabetically by surname and covers petitions numbered 2788 to 19883. While there were various types of naturalization records, the Declaration of Intent and Naturalization Petition usually had the most complete genealogical information. 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.

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 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.

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 other possible localities or ports of entry like Port of entry, San Diego.
 * Try different spellings of your ancestor’s name.
 * Remember that sometimes individuals went by nicknames or alternated between using first and middle names. Try searching for these names as well.
 * 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.
