Thanks, rjessome. I wasn't aware that they were moving to a new system, but that's great news! From what I have seen in the December thread, Buffalo was the slowest Visa office at getting AOR's out, and this will be a great solution.
I bet they're just starting to institute that, and as they receive boxes of applications from Mississauga they're opening them and scanning them - and that is giving people up to date information that their applications have been received. Great news for February and March! But I think they will continue to work through December and January as they have been up to this point - which means news will be slower to come.
So, yes, February is already receiving their AOR's. But they should expect a (probable) two month wait for it to move to "In Process." Whereas December has had a two month wait to get their AOR's, and they are moving almost immediately to "In Process".
Hopefully the new system will be much more reliable in getting up to date information to people. It would make this process much less painful.
Oh, and I forgot to mention (but I'm going to so other people don't get confused or worried), my information hasn't disappeared. It has never been posted. The last update we've had on eCAS is that there's been a decision made on our sponsorship application. We received our AOR e-mail last week, and my eCAS (the applicants) still isn't accessible, and they haven't added information to the sponsors. So, if you're from December (and probably January) and haven't had an eCAS update yet, don't worry. It will come. We're just on the old system.
