Isn't it a solved problem? US universities attract best students from all over the world, from practically every society/country/culture. It's way more diverse, selective, and productive to let universities to decide who gets to come than a rule-based system via DHS.

You will have lots of departments or entire universities dedicated to giving foreigners degrees for cash.

I am sorry if I come across any condescending, but that is how most of the current masters programs are operated. Generally, masters are considered cash cow programs that funds other research and also brings a lot of commerce to the college towns. There are some exceptions, but most of them do qualify for my hypotheses.

That being said, why is it a bad thing then? If the people are spending money to get some quality education that can be regulated within United States, then I don't see any downside in delegating the vetting process to the universities. 4 years in the United States, one family visit per year and it brings a lot of commerce to the country. If they don't perform well, then it's always upto the university to make the judgement.
