I've always wondered how professors and admission committees in the US think about international applicants for doctoral programs in the US.
Why are international applicants selected over (I believe sufficient) domestic applicants at all? Are there some skill differences?
Isn't it more expensive and risky to provide >5 years funding to an international student than a domestic one? When do they think an international applicant trustworthy and appropriate for funding their studies?
I am wondering specifically about PhD programs (not Master etc) because some programs offer funding before even knowing the student in person which seems risky because if I were an advisor it would be difficult to evaluate a student's value for my lab before having actually worked with her.
