I was recommended for admission into the Math PhD program at a large state university in the US two weeks ago and the department informed me that they are forwarding my application to be reviewed by the graduate school. The graduate school said they will review my application and will get back to me in two weeks for official decision. Two weeks have passed and I still haven't received any notification from them, so I sent a polite email asking about my status couple days ago. But at this point, I still haven't got any update.
What should I do now? Thank you.
