Chinese Students Coming Back to the US: $43.8B in Returns
Trump is taking some heat on his reversal to allow Chinese international students back into the US, but as I wrote about before, international students contribute $43.8B to the US economy on an annual basis.
Beyond tuition fees (which feed administrator salaries) think of all the local restaurants, clothing stores, car rental companies, etc. that benefit from predominantly wealthy overseas families sending their kids abroad, especially since there are many high ranking institutions that now use international student admissions (full price) to subsidize homegrown applicants.
I'm not a lawyer, but if you're watching from abroad...when there's a 43B cost associated with a policy decision you can pretty much expect that it'll be walked back/re-negotiated when the dust settles. This goes for any country, not just the US.
