It depends on what you mean. In the U.S. any person who is of legal age who is not a felon and has no misdemeanors for domestic violence can legally purchase a firearm. There are a few minor state restrictions to that in a few states.
A felon cannot own or possess a firearm anywhere in the U.S. unless the felons rights have been restored.
You need to consult with a lawyer for a legal, current and correct answer.
Very simply, a felon cannot own or have possession of a firearm, anywhere in the U.S. There is an exception. IN SOME CASES a felon can have some or all of his rights restored.
In the United States, there is no certain number of years. If you are a felon, you cannot own a gun unless you have successfully petitioned to have your gun rights restored.
No. A conviction of a crime of domestic violence prevents you from owning or possessing a firearm.
Felons cannot own or possess firearms in any state unless the felon's rights have been resotred.
Very generally speaking, in the U.S. a felon cannot own or posses a firearm unless his or her rights have been restored.
Retain a lawyer, have money, have patience and don't be surprised if it doens't happen
No. Once you are a felon, you can no longer own a handgun in any U.S. state. How long you served in prison or the fact that you are now out has nothing to do with it, although, a felon can sometimes have his rights restored, but for information on that, you really should contact an attorney familiar with the process.
You can submit a petition/motion to the court asking that your rights be restored. (WHAT 'RIGHTS' ARE YOU REFERRING TO?) If it is owning a firearm, forget it. Convicted felons may not EVER own or possess a firearm. (Federal Code, USC, Title 18.)
If you are convicted felon, there is no such pardon.
I'm assuming you mean "Can a sex offender own a firearm?" If so, the answer is no. Felons cannot own firearms.
