Well he did technically immigrate to the US from Canada.

Musk emigrated to Canada while Apartheid was still in place in South Africa, while calling him an African immigrant isn’t completely technically incorrect it is quite far from what circumstances most people would imagine that phrasing to mean.

Not sure who "most people" are but the circumstances of all immigrants have only 1 thing in common. Their original citizenship is not the USA. If others have a perceived stereotype, then they should check that at the door.

It really can't get any more black and white than that. The fact of the matter is, in an atmosphere of reduced enrollment by foreign students, we would have less chances of an Elon Musk type person.

Whilst before 2016 it was growing, since 2016 enrollment by international students in universities has been declined. I'm sure you know Musk came to the US for college. Trump administration of course blames "higher costs"...funny given the global economic boom, everyone has more money and the survey says about 50% of Chinese and Indians cites the political climate "would prevent them from applying to a U.S. business school."
