Nepalsundari contract break garda kehy farak pardaina. They can do nothing. In US noone can be bound for anything, so if you find a better offer elsewhere you can quit one and move to another. In fact I did the same, I stayed, trained 4 months in one dhoti consultancy and I ran away from there and I am working at different place now. So don't worry abt that. And generally contracts are made for 1 year but I saw you mentioning 2 years. Try to make one year contract if possible. Ok Good luck
