Interviewed at New Delhi, got pink slip, additional docs asked, kept passport/I797: Jan5 2012
VFS site said passport being send: Jan24
Passport received with visa stamped: Jan28th
This was for my wife who was already working in US (Postdoc in Biological sciences at a reputed school), had gone to India for stamping for first time.
A lot of her colleagues have gone though this same procedure and most of them got clearance in ~3 weeks. ( I assume thats the best case scenario for this kind of processing)
The embassy site had stopped showing any status on our case since Jan23rd, but VFS site did tell the correct status when passport was being returned. Bad thing was that we did not knew that we got the visa stamped until the day we got the passport.
Lots of suspense around this jittery process, and very hard to keep mind at peace.
My suggestion to all stuck: Keep engaged with your employers, start working remotely if possible, and avoid any keywords leading to Technology Alert List in any docs that the embassy asks for in the 221g form. As this might lead to further delay in the process for getting the clearance
gud luck to all
