The Trump Administration's latest effort to reduce foreign influence in US institutions has led to Harvard University, the oldest university in the country.  It's a fair target considering Harvard's enrollment is nearly 30% foreign nationals, many of them from China.  A common criticism of the US is that American schools produce a limited number of graduates in STEM and leadership related fields, inspiring the claim that the US "needs skilled foreign workers" to continue its edge in business and technology. 

This is a fallacy - It's not that the US doesn't have enough students interested in STEM or leadership.  Rather, the problem is that top US universities have been bought and paid for by NGOs and foreign investors; by extension, they allow foreign students to steal spots that should be reserved for American citizens.  

Furthermore, Harvard is widely considered a stepping stone to a successful career in various areas of law and government, but many positions within the school's political enrollment are taken by foreigners (as well a DEI students).

One blaring example of this is the influence of China and the CCP over Harvard, which enrolls around 2300 Chinese scholar per year making up around 20% of the total international student body.
