If ATF sends you a letter about license revocation they are required to set up a meeting/ conference. You can go by yourself or if you need to bring and attorney. Generally you have the opportunity to work out a solution and the Atf still wants to revoke a license you can file an appeal. When it is in the appeal state you can continue until it’s your day in court.
