I asked my professor to write a letter of recommendation in late July, with the deadline of October 1st (which is tomorrow). He responded in the affirmative, and was quite happy to write my LOR. I sent him a reminder email a week ago, which he did not respond to. The deadline is tomorrow, and I still haven't received any notice that he uploaded his LOR.
The other professor I asked already uploaded his LOR, so I'm just waiting on this professor. At this point, unless he uploads the LOR on the deadline, I'm afraid it will be late.
How should I send him an email to prompt him to upload his LOR? I already graduated so I can't visit him in person. Is there a chance he's backing out of writing one for me?
Thanks for any advice in advance!
