> who hailed from selective universities like Sharif Selective for the country I'm sure. Not the world. > they ended up in Canada because of how onerous it was to obtain US student visas (even though they had applied and gotten into good schools). I'm sure they were admitted to great US schools. Or at least claimed to. The visa process is long because of potential technological transfers. Also, the fact that countries like Canada aren't as strict is one of the reasons businesses like SpaceX that are subject to ITAR can't hire international applicants, even from countries like Canada.
