> Americans don't want people visiting, working, or studying on their shores. This is utterly false and unfair. Please don't lump the entire US population with a few ignorant morons who have not seen the world five miles outside their home town. A quick look at our universities is proof enough that what you are saying is incorrect. The last time I visited MIT it almost felt like I was outside the US.

EDIT: If you click on "Immigrants as percentage of national population", you'll realize that the US is one of the lowest in developed countries. So I guess I am disputing your point.
