This is so frustrating Did the letter state that generally exhausted DV visas or it was just for your region?
The lady at the interview showed us a copy of the letter (had plenty of URGET URGENT ... written on it). Apparently, she said that they received the notice only around 4am this morning! We briefly looked through the letter, but honestly, we were in such a shock and so mad that we did not read it well. I did ask her something like that and to my understanding it is for all regions, but certainly not %100 about that.
