I was just thinking that in my instance, the VO in Buffalo claimed to have emailed me an AOR over the summer, which I never got. Then after a while of waiting longer and longer without a response, they finally gave me an AOR in November after I prodded them twice for one.
Soon afterwards, I made a request for the GCMS notes on my file, and noticed they had my email address wrong, and that they've moved my file over to Detroit. So, I've went to the Case Specific Enquiry links for both the Buffalo, and the Detroit VOs, just to be safe. Three days later, they sent me an email, stating that they had previously requested me to send my passport and two passport sized photos, to the Detroit VO. I never got that particular email, either. (but at least they sent me a PPR after I gave them the correct email address) For all I really know, I might possibly have been able to land already, though from reading the notes, they said they haven't corresponded with me as of the 20th of December, aside from the AOR they claimed to have sent, that I never got.
So, I was just wondering if perhaps they may have your email address wrong? Have you requested your GCMS notes to see what's up with your file yet?
