The last mega-corp I worked for had this program where they primarily hired offshore workers, and they offered the really good ones the chance to move to the US on work visas. I made friends with one of them and he told me there is rampant fraud on the offshore teams. There's 2-3 people doing all the work, and they let other people claim it, because that's just the culture somehow. The off-shore managers are in on it and sometimes are one of the few doing the work. He claimed this was the norm at multiple big-name contracting firms he'd worked for. I have no way of confirm any of this obviously, but it did offer an explanation for some of the experiences I had.
