I came to US on F1 visa (MPH), changed to H1b (2 and 1/2 years back) and joined residency halfway thru MPH masters. I am going to India in dec and will get my visa stamped at Chennai consulate. My residency will be completed in june 2007. If any one has similar experience esp. for physicians joining residency without completing their masters degree, please give me some input and valuable suggestions what questions or problems can be expected at Chennai consulate.
