"Mumbai saw a few/New Dehli too/Sing another South Asian tune."

The reason I'm riffing off the Guess Who's Runnin' Back To Saskatoon is because this story is about Indian IT professionals returning to their home and native land -- and that has implications for the U.S. economy.

And if it has implications for the U.S. economy, it will likely impact on us too.

An excerpt:

Santanu Paul is another Indian who spent 13 years in the US, obtaining a doctorate in computer science from Michigan University, working with IBM in New York and leading two technology start-up companies.

Firms like Infosys have been enjoying huge profits

In 2003, he decided to return to India to become the general manager at a Hyderabad-based software services firm.

"Right now, India feels like an exciting start-up company, while the West feels like a plodding large company," says Dr Paul.

Less than a decade ago, people like Mr Narayanan and Dr Paul would have been rare exceptions in a generation that fancied the West as the land of opportunity.

Today, they are among the over 25,000 expatriate Indian infotech professionals estimated to have returned home in the last four years.

That figure comes from the National Association of Software and Service Companies (Nasscom), the premier trade body of India's booming infotech industry.

Around 40% of these professionals are believed to have returned last year alone.

The American Electronics Association, the largest hi-tech trade association in the US, has described it as America's brain drain and India's brain gain. The trend, it says, is challenging America's technology leadership.
