As far as I know, if a person manages to buy a house/asset and open a bank account as a nonresident and passes only a few months in the US, he's liable to pay income only on his generated bank interests in the US and to pay property taxes. But if this person passes only a few months per year in the US despite of having a huge bank account in the country, with related interests, is he forced to invest the money (and get a investor visa) just like a counterpart who wants to actually settle and reside there or can he just be exempt from these requirements?
As it seems to me, an EU citizen wouldn't even need a visa in this case, even if he has a huge bank account and an asset/real estate, since he'd pass a few months per year in the country and not get involved in any business or investorship, because he'd just stay in his asset for the months he can stay, and provide himself with his money in the bank.
Can anyone clarify?
