Student visas in the US come with the right to work for some time after graduation. If the foreign student isn’t valuable enough to stay after a degree and multiple years of work I think it’s fine to send them home.

But me personally, I advocate many fewer student visas.

What world are you living in? Many Chinese come in on student visas, get jobs at FAANG and then have to move back to their country after losing the H1-B. These are the people we want, doing the jobs that we want them to do, and we’re too nearsighted to figure out how to keep them.

Again, these are the most talented, most affluent minds that China has to offer. Sure, let’s have them work for the CCP rather than keeping them in the west.

1) We don’t want them.

2) The O1 visa is open to “the most talented minds” so why couldn’t they get that.

3) They were always working for the CCP.

You do realize how ridiculous you sound when airing #3, right?

As for #1, who is 'we'?

Use game theory for #3:

-You're a Chinese national in the US on a work visa or student visa

-CCP asks you to do something

What do you do?

Let's use game theory for #3.

- You're an American running a business in the US (or somewhere else).

- Trump (or some TLA) demands that you do something, holding a threat over you.

What do you do? Are all Americans actually pawns of MAGA, or the spook agencies? How should the world respond to this implication?

This seems accurate, yes. Do you actually not think this is true?

You are showcasing your ignorance as lucidly as possible, bravo. Befriend some Chinese students studying in the US and you will quickly learn hardly any are fans of Xi and the CCP.

what does valuable enough to stay mean? that they have the job?

Indeed, though if you make that route too easy (or with limited oversight), you end up with diploma mills that aren't actually educating anyone. Incentives are hard to align well.

It wouldn't be hard to select and accredit at least the better universities. Giving an automatic work visa to every foreign Ivy graduate should be a no-brainier. You could take the top 30% or 50% ranked US News universities and accredit those, or some similar heuristics.

Great point, and since the post-graduation right to work is already a thing I believe this has already happened

Is that a thing in most countries? Like if I go to university in Brazil I can easily get a job as a foreigner there?

Brazil isn't a great example here since it is a Portuguese speaking country leading to relatively low immegration, but for Germany, for example a work visa takes 1-3 months to process, and unlike h1b there is no quota.

How so? Anybody who has a student visa had to prove that she or he has strong ties to the home country and no intent to remain in the Untied States, and that she or he only needs to get education in the US to come back and apply it for the home country's benefit.

If these people have not defrauded the US then they would not know what to do with a work visa as they'd be hurrying back home as soon as they received their diploma, pulled by those strong ties and the desire to finally put the education to use at home.
