Laws vary from state to state, but in most jurisdictions you cannot legally own a gun if you have been convicted of a felony, unless your gun rights have been legally restored.
No, never.
You problably can, just make sure you have a permit and are legal of age.
Generally speaking, yes. If you were never convicted, you can obtain a permit. If the charges were expunged, it depends. Expunged is not necessarily the same as having your rights restored.
No. A person under indictment for a felony may neither carry nor purchase, possess, or have access to firearms - it's treated the same as a convicted felon until they are exhonorated.
It doesn't matter. Even if the state has a liberal enough "shall issue" legislation that a convicted felon can obtain a CCW, as a convicted felon you may not purchases, possess, or have access to firearms under federal law. Ipso facto, you could potentially have a concealed carry permit, but you would not be permitted to have a gun.
The most basic answer is no. A felon cannot get a gun permit. However, under some circumstances, a felon can have his or her rights restored.
If you have been convicted of any felony, you cannot even possess a handgun or other firearm (unless your rights have been restored). Additionally, no state will issue a gun permit to a felon, unless your rights have been restored.
If you're expecting to get gun rights back after a felony conviction, don't hold your breath. In some shall-issue states, it is possible for a convicted felon to get a concealed carry permit. However, it's still a felony for them to own, possess, or be in a situation where they have access to firearms, and the CCW doesn't negate that.
It depends, but the basic answer is, the permit is valid unless it has been revoked by the state that issued it. In some states such as Tennessee, you can still keep a permit if you have a DUI, as long as it wasn't a felony DUI.
If you have convicted of a felony, or are under indictment for one, Federal law does not permit you possess any firearm. Title 18, US Code, section 922.
If you have been convicted of a felony, Federal law will not permit you to possess ANY firearm. Under some circumstances, a person that has been convicted of a felony under STATE laws may have their firearms rights restored. You need to consult an attorney. Unless that has been done, possession of a firearm by a felon is a serious Federal crime.
If you are legally "Convicted" then Adjudication IS NOT Withheld....the whole reason for a Judge to have the option of Adj With is to stop short of convicting....IF you have a felony charge - and adjudication is withheld - you are not convicted....
