[Deadpool] Does Deadpool fight crime in the US, or does all his adventures take place in Canada, since he is Canadian? (more questions in this post)

And more importantly, does he have a US citizenship or visa of some kind?. If so how did he manage to get that, has it ever been shown or spoken about before? Did he get it like everyone else that applies for it, or was there some other way he could have gotten it being such a force to be reckoned with. Is there an exception for mutants and super folks?

He interacts with other super heroes. That is pretty conclusive he lives in the us. Also he does not really fight crime. As a Merc he mostly commits crimes. There is no evidence he is legally in the country, or any country he travels to, which is not that rare an occurrence from what i have read. He has travelled  disguised before so the most likley thing is he uses his black ops experience to fake identities as needed. 

An added wrinkle is he has gained some legitimacy in the comics recently but i haven't read much of that so i don't know if he lives/travels under his own name currently.
