yes it was a long wait! i have said this many times but i highly reccomend ordering gcms notes. it will tell you what the officer wrote about your case or if they have even opened it in vienna in the first place! i found out in my notes that we are in interview queue and why we needed an interview. i wrote vienna a long email after waiting 5 months since the officer wrote the note, which was a huge regret to wait so long because after 2 days they emailed me back with an intrview date (maybe if i emailed before i wouldnt have waited so long). in the email i wrote how ridiculous it is to wait 5 months for just an interview. when they sent me the email with the interview date they gave me 2 and a half weeks time to actually prepare for it. gcms notes take 30 days to get and if i hadnt got them from before we would have never knew why we were getting interviewed in the first place. not only that but my husbands interview was in a different country and he needed an interpreter that alone was hard to find. having the gcms notes we knew exactly why they wanted the interview and we prepared from before by printing pictures, keeping all conversations instead of deleting them and kept our receipts. gcms notes are only $5.. maybe u dont even need an interview and its just in a queue for passport request!
good luck
