Before 1906, the information recorded on naturalization records differed widely and often didn't mention the immigrant's town of origin or parents' names. In 1906, the Bureau of Immigration and Naturalization was created and later renamed Immigration and Naturalization Services or INS. Some results included standardized forms throughout the country and copies of naturalization papers sent to the INS in addition to the court keeping a copy.

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

 * Add any new information to your records
 * Find records in his or her country of origin such as emigrations, port records, or ship’s manifests
 * 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 and 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?

 * Check for variant spellings. Realize that the indexes may contain inaccuracies, such as altered spellings and misinterpretations
 * Look for an index. Local genealogical and historical societies often have indexes to local records
