The North Dakota Naturalization Records index was compiled at the State Historical Society of North Dakota, where all original county naturalization records are preserved and have been microfilmed. In cooperation with the NDSU Institute for Regional Studies, the index is made available as a searchable database. The database contains over 212,000 names, giving the county where the declaration of intention (1st papers) was filed and the naturalization occurred (2nd papers), the date of both events, and from what country the person emigrated. Consult the State Historical Society of North Dakota's Naturalization Records' information sheet regarding the history of the naturalization laws, types of records and how to use them. You may also consult the Institute for Regional Studies' information page for the scope and content of the records.
