As previously mentioned, federal law prohibits aliens who are illegally in the United States from receiving or possessing firearms. Additionally, subject to certain exceptions, aliens who are in a non-immigrant status are prohibited from possessing or receiving firearms. 18 U.S.C. § 922(d)(5). Therefore, sheriffs must make additional inquiries of applicants for pistol purchase permits to determine their alien status. The sheriff must first determine if the applicant is a citizen. If the applicant is not a citizen, the sheriff must obtain additional information on the person to include his/her country of citizenship, place of birth and alien or admission number. If (1) (3) 8 applicable, the sheriff may have to determine the basis of any claimed exemption from the nonimmigrant alien prohibition. For example, a non-immigrant alien could possess or receive a firearm if he/she is in possession of a valid hunting license issued in the United States; is an official representative of a foreign government accredited to the United States; or has received a waiver by the United States Attorney General. 18 U.S.C. § 922(y).
