It definitely correlates with a region where applicant resides - those several people who I know from Vancouver, BC - all where transferred from Buffalo to Seattle. There might be other additional reasons of course..
Hi,
I submitted full application to Buffalo on May 20, 2010 and got my 2nd AOR on October 12, my ecas changed Oct 19 - "Aplication Recieved by visa office"..
So I guess now its a waiting game..
Good luck everybody.
