Hmmm... And the U.S would not want a guy who was good enough to get a scholarship to Stanford, why exactly? We'd be stupid not to take him if he's willing to stay. Also his family already has green cards. They are not asylum petitioners who may or may not be granted asylum or illegals...

Sound like you have finances. Have your family consult an immigration attorney just in case but I don't see why they would not grant you an F-1....
