Ah, the Trump Cult. Always eager to cut off their own noses to spite their face, especially if it. You'd burn down your own house to piss off your leftist neighbours, you're just that stupid.
Every nation in the world will be more than happy to get them, asshole. We'll make the billions you're driving away. In fact, every major university in the world is already recruiting them, and their graduates.
Just like Russia and Hungary, you'll be left with an aging under-educated population unable to keep pace with 21st Century jobs or science.
Foreign students were contributing $43.8 billion to the US economy but that's going to sink like a stone next year as students stay home, or go to friendlier countries not run by raging lunatics. The result will be that tuition at American universities will be rising yet again because foreign students lower the tuition costs for American students.
Trump's policies are destroying the USA, and maybe that's a good thing.
