We have both types. A lot of Indian contractors get paid very little money and they are often hired through two or three agencies that all take their cut. The Infosys guys are paid a little better but still under market and from what I have heard Infosys is slow in processing their green card application. I think in both cases it would be better if the H1 people didn't need a company sponsor but could change jobs easier and apply for visas themselves so they can't get held captive by the company.
