Unfortunately, nothing yet. I am in the same soup - everything right from visa to travel/housing is held up.
As others have said here, main thing to margin for is the appointment wait time. Another one is the processing time. The latter is generally quite small but sometimes if 221g is invoked, it can take quite some time for visa approval. Read up on that here. If you think you are very unlikely to have 221g invoked upon, just margin for appointment wait time at the local consulate and you should be fine. Since Fall semester generally starts in Aug/Sept, there is still quite some time including margin.
In the meantime, I would suggest that you start looking for an apartment to rent which can get tougher to find as time goes. Travel is again dependent on visa approval but you can possibly book flight to the US and cancel it later if things don't work out. I had done this once for an internship that I didn't end up going to and the round-trip cancellation cost me just $100. I would prefer that over booking a more expensive flight later on.
I hope your funding works out. All the best!
