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. Additional records and/or images may be added to this collection in the future.
