North Dakota Naturalization
Most of North Dakota's naturalization records have been transferred from the clerk of the district court offices in each county to the State Archives and Historical Research Library. These records represent the bulk of documentation pertaining to immigration and naturalization proceedings in the state. The records document individuals who became, or applied to become, citizens between 1873 and 1952. An index to all fifty-three county naturalization records can be found on the State Historical Society of North Dakota's website.
