@erein42 @gotmilk332, I just emailed Fulbright (FBstudent@iie.org) 1/31 asking them if they had an update on initial notification emails that have not yet been sent, and within 3 minutes the department of state forwarded me an acceptance email! Mexico ETA. Since so many Mexico ETA applicants had already heard back and were already being scheduled for interviews, I assumed I was rejected, but that just goes to show that you can only decipher so much about the selection process from a forum.
If you haven't heard back, maybe try reaching out to Fulbright! It was helpful for me. Good luck!
