Wyoming Naturalization and CitizenshipEdit This Page
From FamilySearch Wiki
Naturalization records have generally been filed with the clerk of the district court in each county courthouse. You can obtain copies of declarations, petitions, oaths, and orders by contacting the clerk's office. The Family History Library does not have copies of these records for Wyoming.
For naturalization records after September 1906, contact the National Archives— Rocky Mountain Region (Denver) at http://www.archives.gov/rocky-mountain/. or the local office of the United State Citizenship and Immigration Services (formerly INS).
