Just guessing, but the place most foreign students come from is China.

There have been multiple claims that China is using oversees students to steal knowledge or that University have become to dependent on the money from Chinese students and cooperations. Be aware that I'm just saying such claims did happen not that they are true.

The fact that many countries also doesn't want to open border to the US again for now might also play a role.

I think you got it backwards. Chinese students are not stealing the knowledge, they are creating the knowledge. They do research, the hard work and publish papers. A lot of them want to stay here, but anti-immigration policies leave them with no other choice other than go back to their home countries and work for CCP.

It almost looks like Trump is forcing top students to leave US and bring their knowledge back to China to benefit CCP.

Works kind of imilar in Germany. Stay for your studies, which are basically free for everyone who enrolled at a university. Be forced to leave if earn under a certain threshold. That threshold was roughly double of my first salary right after graduation, and I was on the higher end of my semester. Having applied this threshold to my semester, we would have all been forced to leave. Kind of cracy, if you ask me.

No this are not thinks I believe. This are claims which came up one different articles in the recent year(s) on hackernews and are things you might hear from people which are strongly anti-foreigen students or people like Trump.
