@ ramansra, Jassi was right, I was the man faced interview after In Process. First they asked me to send some pic's in 30 days. i sent 30 pics of marriage and reception. After around 30 days i have received interview letter.
I posted my interview experience here..

After the interview the immediate next day they dispatched my medical papers.
Be confident, don't worry. Every case is different. As you have submitted some additional info also like insurance and ration card or something [i found in previous post] might give you some mileage. otherwise if you send simple photos your case is also will be in favor of interview. You will get your medical instructions very soon.
