I want to share my recent experience in case anyone else is faced with the (terrifying!) task of rescheduling their AOS interview. I had read many horror stories but, at least in my case, it was no big deal.
So, I am a first-year Spanish teacher and I am taking some students to Madrid in March. Of course, our interview was scheduled for a day that I am out of the country. I freaked out and was so worried!
We simply sent my flight itinerary and a letter from my boss explaining why I would not be in town to our LOCAL office. They sent us a letter in about a week later
saying that our original appointment had been canceled. I was nervous but then our status changed online that we were ready to be scheduled again. A week later we had the new date.
Now we just have to prepare for the interview. Another nerve-wracking situation!
