Virginia does not require a license to purchase a gun, nor to possess one. A Concealed Handgun License IS required to carry a concealed handgun in public places if you are not a law enforcement officer, or one of the few others permitted to carry concealed. If you are 21, can own a handgun legally, can pass a background check, and demonstrate that you have had adequate training in firearms, Virginia will issue a concealed handgun license.
Check with whatever agency issued it.
