I may be missing something here (that's probably the safest bet! ), but I'm thinking someone from Illinois can't purchase a gun in Georgia, at all. There's nothing for a Ga FFL to do, because he can't transfer the gun to the guy with ILL residency, no matter what.Also, be aware that to be legal, the transaction has to be legal according to the laws of both states, which may be the reason that some FFL might not want to do a transaction for a buyer from a state which has rules they are not familiar with. For ex. if someone from IL. wanted to purchase a gun in GA. the Ga. gun dealer has to make sure that the purchaser is legal according to the insane IL. laws.
All he could do is ship the gun to the guy's FFL back home in Ill, and the Ga FFL's obligation would be only to verify the validity of the Ill FFL (and maybe the legality of the particular weapon in Ill.)
And if the guy from Ill is here visiting, and wants to sell a gun to his buddy/brother, a Ga resident, as I understand, the FFL is completely free to do the transfer, and IIllinois' laws don't come into play at all.
Is that not correct?
