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

 * Use the information found in the naturalization record to find a ship manifest
 * Search for vital records, such as marriage and death
 * Use the information found in the record to find additional family members in census records
 * If applicable, search for military records as well

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
 * Try different spellings of your ancestor’s name
 * Remember that sometimes individuals went by nicknames or alternated between using first and middle names, or even initials
 * 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
 * Consult the California Research Tips and Strategies and its Record Finder to find other records
