Nevada Naturalization and Citizenship
Naturalization records may have been filed in any court of record, but most people who applied for citizenship went to the clerk of a district court. You can obtain copies of declarations, petitions, and certificates by contacting the appropriate clerk's office. The Family History Library does not have copies of these records.
The Nevada State Library and Archives has no naturalization records.
The National Archives—Pacific Sierra Region (San Bruno) has records from the two U.S. district courts in Nevada for 1853 to 1956.
For naturalization records after September 1906, contact the National Archives—San Francisco Region or a federal office of the Immigration and Naturalization Service.
