Have received admission to Columbia MSFE with a short period to respond, help with what to do?

Hi!

As mentioned, I've just received admission to Columbia's MSFE program. I'm ecstatic!!! I've been given two weeks to let them know what I want to do and although my first instinct is to accept, I want to ensure I'm making an informed decision. I'm mainly waiting to hear back from Stanford's ICME MS program and the University of Washington's CFRM MS program. Does anyone know when I might be able to hear back from them? Should I email to ask for an early admission decision? Can I even do that?

Thanks for the help!
