<p>@ambiance, have you tried contacting your professor directly by phone? A busy professor may be receiving numerous emails! If things are really down to the wire, and you’ve lost communication, I don’t think it’s too forward to give a professor a phone call reminder, right? You might check with the department for a contact number if you don’t already have one.</p>
<p>I think there is great advice in this thread. Many of us seem to be in this situation. Ultimately we all just want admission into our desired program, so we are in a sense placing our hopes and dreams in small part in the hands of our recommenders. I think grad school admissions committees probably recognize this and should give the according leeway for this aspect of the application. Both the applicant and the professor are probably doing the best they can.</p>
