As an interviewer in a big tech company, it seems all candidates I interview are foreigners who often graduated in the US. Either the company discriminates (which I really doubt it does), or there aren't enough qualified Americans for some jobs. And even if there are, the largest pool of candidates, the better.
More competition is not inherently "better" nor does it necessarily yield greater innovation. Trying to impose arbitrary competition as some abstract principle is just masochism.
This ratio gets worse because American students are disproportionately more likely to follow up their engineering undergrad with law or business school, so even if they may be engineers they’ll get into business and/or something like patent attorney going forward.
There's nothing wrong with being a librarian or getting an MA in Museum Studies, aside from the price of getting the degree and the low odds of getting a job without waiting for someone to die so another position opens up.
There's a reason you won't find a lot of foreign students pursuing them, though.
2) If you've got a problem finding candidates, there's 16,000 more on the market now. Congratulations!
3) If you think there must be something wrong with those 16,000, well, that would explain where your pipeline is going wrong.
I don't see how this is even possible. There would be a memo from the CEO to 1000s of recruiters asking them to favor foreigners? that would leak immediately.
This is still the case in US Comp Sci programs. There are some Americans in these programs but it's mostly Indian and Chinese. The American kids gravitate to the business schools.
