This has been going on for years. I am in the IT world and my first experience with this was around 1995. Indian companies put 8 men in a run down 2 bedroom apartment. Pay them 18,000 per year. Bill them out at rates sometimes in the hundreds per hour. Indians do it because they have to be sponsored, uninterrupted, for 4 years in order to get a green card. If they have to get a new sponsor, the clock resets to zero.
OK, you answered my post 15 question.
