I know I'm being completely paranoid, but have you ever gone back to your USTA application to look through it again? If you log in, it just says "print application" and pulls it up as a .pdf, but then it looks incomplete. I don't see my essay or transcript or any of my uploads--not like you do with Fulbright. It makes me worry something happened and my full application wasn't submitted! I wish I could quit worrying about it...
Anyway, I'm also worried a rejection from the USTA portends rejection from the Fulbright ETA, since the USTA is supposed to be less competitive. I thought I was just hedging my bets...but now I'm bracing myself for the worst: double rejection.
