Tuck Rickards, leader of the technology sector at recruiting firm Russell Reynolds Associates, says foreign firms, especially in high-growth markets such as Brazil, China and India, are increasingly looking outside their local markets for talent, especially for workers who know how to manage large operations.

Unclear is how wage competition from overseas will affect U.S. worker salaries. H-1B visa use alone was for a decline of U.S. wages.

But for now, Murthy has to tackle more immediate concerns, and that means explaining to investors what steps he is likely to take if Congress acts to restrict visa use, imposing the so-called to limit H-1B and L-1 visa holders to 50% of the U.S. workforce.

If that law passes, Murthy will need to increase his U.S. workforce by 15%. He will do this by hiring more permanent residents and citizens and using Mexican nationals who can work in the U.S. under the provisions of the North American Free Trade Agreement (NAFTA) without the need for an H-1B visa. He will increase the amount of work done offshore.

"It won't have a big impact on our company," said Murthy of any visa restriction. But he also believes that as wage levels rise in India and competition continues, his firm will compete on its ability deliver value and certain outcomes to a customer, not on the number of people it can assign to a project.
