As an applicant to Mexico, I emailed the person who sent me the initial notification that I was recommended (Fulbright-Garcia Robles, in Mexico). I don't know if other countries work that way, or if applicants received emails from the US Fulbright office on the first round notifications.
I just asked if they had any information on the date that final notifications would be sent out, since I had been told during my interview that it would be one month, and that time period has passed.
Very politely, and very thank you. hehe
Although my interview did not go well AT ALL, so I think it would be miraculous if I got it. But, as everyone knows, the uncertainty is unbearable....
