Hi I've recently received a fully funded PhD offer from University A, which is (for now) my top choice. I also have an on-campus interview scheduled for mid March in University B, which I'd really like to attend before making my final decision.
The program at University A is very small, and their website explicitly states that they aim to admit a maximum of two people in the program each year. However, I've learnt that they sent out five offers this year.
Now, I'm aware that programs typically send out more offers than they have spots. I'm also aware of the April deadline, until which we're free to accept or decline offers.
My question is the following: what will happen if, say, two or three people accept their offer sooner that me? Will the university rescind the offer of admission and/or funding, given that all the spots are filled?
Maybe I'm being paranoid, but I'm an international student, unversed in American academic culture. In my country, it's not uncommon to admit students on a first-come, first-serve basis.
