Ok so I browsed through this website and it seems like there is a general consensus that public schools accept fewer international students because they don't receive financial federal aid and they cost more. I don't really understand this argument or how universities run. It might be obvious to some of you, but it's very confusing and I hope someone explains the difference to me.
For STEM PhD programs (mainly biology and chemistry), departments only have to consider two bills when accepting applicants: tuition cost and stipend. Stipend is fixed across all students and there should be no difference between domestic and international applicants. As for tuition costs, all STEM PhD programs WAIVE tuition costs for PhD candidates. The way I understand this is that there are no tuition charges, and so there is no sense in saying domestic students are cheaper than international students. If my understanding is valid, then where does the government/federal support fit into this situation? What is being subsidized?
Thank you for taking the time to reply!
