the first sentence does not make sense at all. the second sentence is close. "been to" means you were there but have now left. so you can say "he has been to America." Or you can say "been in" which is like saying "lived in". Example: "he has been in America for 3 years" or "he has lived in America for 3 years" or "he has been living in America for 3 years." they are all saying the same thing.
