I havent heard back from a good number of MSTPs that I applied to. I know many notify/start screening late and others have silently put my app on hold. However, I thought Id call NYU and ask whats up. My file was complete in August and I called on 12/3. They said theyd call me back, never did...but the next day I got an interview invite via email. Obviously my call had some impact so Id encourage others to call if youre in any doubt regarding your status. The worst (and likely) thing that will happen is they say "your file is under review, we will notify you when there is a change in your status...blah blahh"
