I worked at one of these firms in India before. The common practice there is to file for a H-1B visa in anticipation of future onsite trips. Many hundreds go unused. A number of my collegues got their visas stamped, but never travelled. Some were never intended to be used at all. The project manager told me they are just a backup in case of emergency situations (e.g., an onsite contractor might have to go back to India within short notice etc.) I think this is the main reason behind the recent inflation in number of H1-B applicants. This is certainly abuse of the H1-B program!
These companies should not be granted so many visas. If you want to increase competitiveness grant more visas to foreign students from top universities in the US. Giving out visas to these companies will only get you mediocre people who know nothing about computer science (yeah well, they know a lot about time sheets, status reports and how not to manage a team) - ofcourse there will be exceptions, but the largely the crowd that comes here aren't any super skilled programmers. They would just know a bit of their client's business and a few programs in some subsystem that is written in COBOL.
I am happy to have left that sweat shop in pursuit of my masters degree a couple of years ago. Never wanna go back to them! they do not do anything related to computer science there! it's all plain business. You are not allowed to fix ugly code if you feel like it - the client should be ready to pay for that too !! no smart ideas here please
Trust me, tis nothing like cutting edge. Far from it. I laugh when Bangalore is called the silicon valley of the East!
