Hi Shanu,
Welcome aboard. Just an idea for your time-frame, I applied in August 15th. my file was sent to Srilanka September 15th and am still waiting, my wife was told by some source at the embassy they do not work on each file individually, they do it in groups, so I guess they collect a few months together and work on it together, if you read earlier trends it will show you that some people who applied in May, June, July got their visas in November, so if you are lucky may be you do not have to wait that long. Could be that August, September and October will be called together. But its definitely is a few months wait.
Take care
Coiler
