A solution to that would be tightening up admission requirements. But if universities deem that applicants are legit, there is no detriment to the supposed "influx" that you are pointing to. At that point, that's just the US drawing in trained labor force
They have to get accepted into a program and graduate and they have to have the funds to pay tuition. Then they'll work productively here and pay taxes. I can't think of any reason why this would be a bad thing except the bigoted "ugh, too many Indian people."
Absorbing educated people from other nations is an economic superpower.
Lower ranked US universities will grant admission to anyone who can afford their fees. Majority of the people coming to the US are from tier 3/4 colleges in their home country. There are few states in this particular country that have consultancies submitting thousands of student applications. Everything is taken care of - from the application form filling to preparing SOPs and letters of recommendation. Always a good idea to understand the ground reality before jumping to conclusions.
Because American's have chosen to have immigration opportunities spread among different countries and specifically written that into our system? Because I don't want a system that promotes elites that 'have the funds to pay tuition'? None of my grandparents could have afforded that high bar. If you have the funds, you don't NEED to immigrate as much as others do.
