Stamping in Chennai - COS from L1B to H1B

Hi Saurabh,

I had a COS from L1 - H1 while in US. I am planning a trip to India.

I will need to get my H1B stamped.

What all will I be asked? Will they ask me why I got a COS?

I have not been to India since 3 yrs. When I go for stamping how will they perceive this?

Please advice any important points which I need to know.
