Omg, I can't believe I found a situation which is very similar to my situation.
In my case, things are not so bad about deadlines, since my international office deadline is July the 1st or something like this. However, I am freaking out right now too, because I can not do anything (like housing f.ex.) without financial statement. And my grad coordinator doesn't answer my email. I am also freaking out because they (PI, grad coordinator and program director) don't tell something like "please, wait, we will prepare this documents for you later". They just avoid answering this question. As I believe, perhaps it is a question of policy.
In a paroxysm of rage (lol, i was not ok at this time) a have made a question on "stack academia"
So, I am still curious about this situation and waiting like an idiot.
NonparametricBananas, did you get your financial statement?
