Well vamsi,
Welcome to the land of pain, I'm pretty much in the same situation than you, so I know how you feel.
I'm sorry, but I do not have any information that can really help us.... is hard to find a place that have the money to pay a research fellow, and are willing to go through all the visa paperwork.

What I have been told is that usually takes 3 or 4 years of work to get a spot in an american program, because you need to build up your "american CV", as you probably know already, everything that you did in your home country is pretty much worthless for the american program.

Sorry that this reply do not help you in anyway... but if the goel is to get inside an american program, be prepared to expend, at least 2-3 years (I'm probably short in that prediction), with no guaranty? and probably you will have to go back to do your training at your home country or try in a non surgical-primary care type, that are more open to the FMG.
