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. | 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.
