A friend of mine is Swedish and works for a US based regional airline. In the last year hes 'moved' back to Sweden but still works in the US. Basicly he jumpseats back to Sweden every chance he gets (twice a month) and hasn't needed to change any other aspect of his life. As far as taxes are concerened, I'm pretty sure that on paper he works and lives in the US. As for health insurance I know that he gets health insurance through work, probably also is able to hold onto Swedish free health care as well. As far as money and banking, I think that he gets paid into an US account and from there transfers it to a Swedish bank as needed.
All in all, its a lot of traveling but it works for him. Not sure if this was any help, but at least lets you know it is being done. Good luck!
