World's talent opts to leave USA

USA Today reports:

More skilled immigrants are giving up their American dreams to pursue careers back home, raising concerns that the U.S. may lose its competitive edge in science, technology and other fields.

"What was a trickle has become a flood," says Duke University's Vivek Wadhwa, who studies reverse immigration.

Wadhwa projects that in the next five years, 100,000 immigrants will go back to India and 100,000 to China, countries that have had rapid economic growth.

"For the first time in American history, we are experiencing the brain drain that other countries experienced," he says.
