Wipro? Kind of a biased party. My group at MegaCorp has hired an army of testers from Wipro. (they're generally competent within their job description, which is about all you can ask of any consulting company) Anyway, the point is that Wipro is in the business of providing cheap bodies to large companies. That's what they do. (one of the many things they do, actually) Of course they don't like visa restrictions.

Interesting point about my group's work with Wipro: even if we wanted to hire such a number of people from the US, we probably couldn't. It would be too expensive and they would be hard to find. BUT, hiring an army of testers was a terrible idea in the first place. It was a bad solution to the problem. 2 clever people with the license to act couldn't solved the same problem for a fraction of the cost, with better results.

So I wonder if this kind of labor acquisition is needed only by dysfunctional companies? Hard to generalize from a single sample, but interesting to consider.
