I'm an undergraduate student in Physics and Mathematics, who plans to do a PhD in Physics or Mathematics. I know when you are doing a PhD, you can be a TA or RA if it is provided, so that you can handle financial issues or you could be accepted into the PhD program with funding or scholarship (I don't remember the correct term) but what about loans or any other financial support for international PhD students in US and UK?
By the way, if it any helps, wherever I go for PhD, I will take their citizenship, at least apply, since I have no intention going back to Turkey.
A side question: Apart from the loans, what is the general procedure for financial offer from the universities? I mean how does it work?
Note: I'm from Turkey.
