Guys,
A minor update in my case (Filed Nov 14th 08, AOR March 18th 09, File transferred to Detroit Oct 27th 09). I sent an email to Detroit consulate today in response to their previous email that my application was screened on Nov 10th 09 and correspondence was being prepared to be mailed. However, todate I received no correspondence from them (after 2 weeks of waiting). Their email today said they have not yet sent any correspondence.
To make a long story short: Paperwork is moving extremely slow at this consulate. They are taking more than 3 weeks just to inform an application about the next step after screening the application. I'll update again when I actually receive the letter so we can get an idea as to how long it actually takes just to send a correspondence.
The good thing about Detroit consulate:They are extremely fast in replying to emails (generally reply back in a couple of hours after sending emails). I guess the number of files being processed at Detroit are way less than those at Buffalo, so Detroit communicates with applicants pretty well.
