I got my medicals done in Chennai in early November, thought I would post my experience while it is still fresh in my memory.Note that I am not a Chennai resident - I reached Chennai at 6AM on the test day, and had booked my return the same night. I wanted to finish both the lab and the checkup the same day.
A)Procedure at Lister
If anyone's interested: I had an appointment today for H1B visa revalidation. Overall it was a smooth experience. I was asked for my paystubs though.
Degree etc was not asked for. Total interview time was 2 minutes. The only question I was asked was whether I am working for the same company for which I had received an H1 visa previously. In my case that holds true. I also had an F1 visa previously. US Degree.
