Temporary visas to work in the U.S., known as H-1Bs, have become highly controversial. Two U.S. senators are investigating how foreign companies are using the visas to bring workers into the country. They suspect that Indian outsourcing firms are using H-1Bs to facilitate the outsourcing of American jobs. India’s Infosys (http://www.businessweek.com/ticker/) and Wipro (http://www.businessweek.com/ticker/) received more of the visas in fiscal 2006 than any U.S. company. Here’s a look at how many of the visas they and other top Indian outsourcers used.
