Hello all, sorry if these are really basic questions... I'm probably just overthinking it and confusing myself, but: can a USA citizen just hop in a plane and get a Visa stamp in their passport on arrival at the airport? If so, does that grant them the status of a temporary resident? Also, if all they need is a stamp, what sort of information/documents should they bring with them to ensure they get the stamp? Who do they talk to to get the stamp?
