Most of the consultancy they are in market to make money. I got job from Vastika. They are doing good to me so far. They provide me health insurance $4/per month after 3 month. They raise $5000.00 after 6 month. They said, they will increase $5000.00 after 1 year. I start from 63,000. About contract, vastica says do not leave the first project. I do not see, why anybody going to leave first project. Yes, I do not like about vastica is they marketing policy and need to prepare for interview. I have my friend who is from Indian consultancy, who do not get pay in time, do not increase salary in time. try to cut hours. About Green Card, they promish after working 3 years they will file.
