Bad news. If you were convicted of misdemeanor domestic violence, you lost your gun rights under federal law. Currently, there is no viable remedy to have your gun rights restored for this disability.
If this disqualification applies to you, please read this post before you call the office. Seriously, I cannot help you.
If you were convicted of domestic violence in another state and the conviction was expunged or set aside, call the office. You may still have some options.
If your charge was dismissed after a deferred finding or finding under advisement (e.g., first offender), call the office. As long as the charge was ultimately dismissed, you might be eligible.
