Hi!
I'm on the same boat. I've already sent my first application, I wanted to be considered for early notification, but my last recommender hasn't send his letter (I know he started it when I reminded him, it's maked as "in progress" in the application management page) and I can not change my recommenders (since I've already submitted and paid the application fee), so I'm guessing I won't be considered for early notification and I'll have to wait for the regular deadline
How do I politely remind my reocmender that my future depends on this and that I'm freakin' out? I've written several emails, and sent him reminders from the application... I'm starting to get pretty anxoius (and angry.. he told me he'd do it!). He's my star recomender, everyone I asked suggested he should write it, that he'd boost my chances to getting into most schools (I'm an international student, he was my professor in college, but now has a very prestiguous job in the US...being an international student, getting a LOR from someone like that is next to impossible, and in theory I've got it, except he won't actually send it!).
I've obviusly stated seraching for an other recomender for the rest of the schools I'm applying to, I don't wanna be in this incredibly stressful situation again.
