No, they cannot.
probably. Speak to a lawyer.....................
A felony conviction will remain on your 'record' indefinetly, until you have it expunged via Court order.
No. Expunged only means it's not visible to the general public - it doesn't make your felony conviction go away. You still remain a convicted felon, your felony conviction will show up on any background check done on you, and you can't own, possess, or have access to firearms under federal law.
It depends on what state convicted you. All states have different procedures.
No, you cannot purchase a firearm if you have a felony conviction.
Wrong. A felony conviction IS a felony conviction. You may be able to get the offense expunged (IF Arizona is one of the few states that will restore your civil rights).
Yes, you can not. Being denied ownership of or access to firearms is a consequence of a felony conviction.
No, and it doesn't vary between states because it's a matter of federal law. Having a felony expunged does not make it go away - it only removes it from the public domain. You still remain a convicted felon, and thus may not purchase, possess, or have access to firearms.
No. If you get a felony conviction anywhere, you may not own, purchase, or have access to firearms anywhere else. That's federal law.
Felonies are forever... Expunging a record is very difficult and very costly.
Yes - BUT, DUI is only a felony at state level in some states, and not a federal felony. Thus, it is possible to apply for relief of disability to regain your firearms rights.
A felony conviction record is forever unless it is expunged. If you qualify for expungement you can have the offense expunged. HOWEVER - an expungement only hides the conviction from the general public. Law enforcement, the courts, and government agencies will always have access to it which would prevent you from ever possessing a firearm.
