This is not something new, It has been happening from a very long time, I am a Indian myself I know many people have formed such Consultancies in US and hire people from India filing for a position in their office, But eventually making you find job with whomever you choose and taking a part of your pay until you get Green card or some so called good ones just take your full net pay for 3 months in installments. And these type of firms also now create fake projects have desktops setup fake clients setup, hire so called "IT Professionals" from India stating he is a "Java |Ruby Specialist" creating fake documentation for the project, Fooling the immigration panel and eventually bypassing a system with wrong intentions.

On the flip side they also have gotten smarter now by hiring new grads from India who come to US to pursue "MS in tech" add some fake experience to them, train them for a month or two and leave them in the market for potential suitors, only the people who have passion to learn and thrive get to the top and are in the top currently in US markets.

Indian IT service provider companies are a different animal all together, they abuse the system by putting up multiple applications (Here you get some descent resources with no fake qualifications) but still it doesn't do justice to a startup that wants to hire one good resource from abroad because these sharks have already filled up the quota.
