I am in a situation, just like yours, subee. Graduating in December in Finance, and I applied for opt a week ago. I also have heard about some Indian consultancies, mostly in Virginia. I tried to collect information of them, which was about a year ago. Now, I have come to conclusion that there's no worth going to them. First, H1B has been converted into a lottery(better play megamillions everyweek), and I have heard nowadays that even the consultancies aren't able to provide us jobs. You might have to work for them for months before you are placed into a job, and it might already be near your OPT expiration. Even though I have not already decided anything, going to consultancies doesn't seem as much fruitful as you, and me have expected. I am not discouraging you, though. Anyway, all the best for what you do.
