The definite possible advantage of claiming foreign citizenship while going to college is Foreign Aid funds to attend college on the U.S. dime.
It's FAR easier to get financial aid as a black American student than it is as a foreign student.
My wife is a college professor. Her university actively recruits foreign students. Why? Because they pay FULL PRICE. With the exception of Mexican students, there is very little aid available to them (foreign students). This "foreign aid" meme is a canard.
Which foreign aid funds? What program do you allege Barry benefited from as a foreigner?
FYI, foreign students very rarely get any aid. It's generally much easier to get scholarships if you are a US citizen.
