A person is not considered convicted for Gun Control Act purposes if he has been pardoned, had his civil rights restored, or the conviction was expunged or set aside, unless the pardon, expungement, or restoration expressly provides the person may not ship, transport, possess, or receive firearms.
Persons convicted of a Federal offense may apply for a Presidential pardon. 28 CFR 1.1-1.10 specify the rules governing petitions for obtaining Presidential pardons. You may contact the Pardon Attorney’s Office at the U.S. Department of Justice, 500 First Street, N.W., Washington, DC 20530, to inquire about the procedures for obtaining a Presidential pardon.
Persons convicted of a State offense may contact the State Attorney General’s Office within the State in which they reside and the State of their conviction for information concerning any alternatives that may be available, such as pardons and civil rights restoration.
