The Indiana State Archives is the official repository for all Indiana naturalization records prior to 1951^* as designated by the Indiana Rules of Court, Administrative Rule 7. The archives is pursuing the acquisition of naturalization records from the counties for the purposes of conservation and to provide greater public access to this valuable Hoosier historical resource, but, at this time, not all naturalization records reside in the Archives. Please refer to this page often, as the Archives expects to continue adding information to the database as the records become available.

All naturalization records accessioned by the Archives are microfilmed and a portion of the information they contain is entered into a searchable database. The results of the database search will include the following fields: Surname, first name, nationality, date of arrival, and county book and page location. A complete naturalization record may be obtained by contacting the Archives.

^*Note: These records do not include order books, which are held as permanent records by the counties. Post-1951 naturalization papers are stored at the Immigration and Naturalization Service, 425 Eye St., NW, Washington, DC 20536. Another helpful resource is the National Archives, Great Lakes Region, 7358 South Pulaski Road, Chicago, Illinois, 60629. Their collections include a name index of citizens naturalized in the Great Lakes region.
