In the US, Federal law (Title 18, US Code, Section 922) provides that a person convicted of a felony may not possess a firearm. You can OWN one, but not possess one. Many states DO have a process where a person that has been convicted of a felony may apply for a restoration of their right to own a gun. No such provision is made for convictions of Federal law. You WILL need an attorney in your state to provide effective legal guidance in this.
The short answer is, if you are a felon, you can't own or possess a gun.
Never
If a person has a felony you cannot own a gun. It does not matter how long you have had the felony.
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.
Question is unclear. How can you have a felony record on a NON-conviction? You were either convicted of a felony or you weren't. If you weren't you're not a felon.
No
Indictment for a felony- you may not POSSESS a gun.
No, they cannot.
You will need to consult a lawyer and give him/her ALL the details of your conviction and sentence. It will not be easy to get your second amendment right restored and it will cost money.
No. If you get a felony conviction anywhere, you may not own, purchase, or have access to firearms anywhere else. That's federal law.
You will have to discuss your exact situation and all details relating to the felony conviction with a lawyer.
Yes. Conviction of a felony, being under indictment, being a fugitive, or being convicted of domestic violence are disqualifiers.
