Why Skilled Immigrants Are Leaving the U.S.

New research shows that highly skilled workers are returning home for brighter career prospects and a better quality of life
By Vivek Wadhwa

As the debate over H-1B workers and skilled immigrants intensifies, we are losing sight of one important fact: The U.S. is no longer the only land of opportunity. If we don't want the immigrants who have fueled our innovation and economic growth, they now have options elsewhere. Immigrants are returning home in greater numbers. And new research shows they are returning to enjoy a better quality of life, better career prospects, and the comfort of being close to family and friends.

Earlier research by my team suggested that a crisis was brewing because of a burgeoning immigration backlog. At the end of 2006, more than 1 million skilled professionals (engineers, scientists, doctors, researchers) and their families were in line for a yearly allotment of only 120,000 permanent resident visas. The wait time for some people ran longer than a decade. In the meantime, these workers were trapped in "immigration limbo." If they changed jobs or even took a promotion, they risked being pushed to the back of the permanent residency queue. We predicted that skilled foreign workers would increasingly get fed up and return to countries like India and China where the economies were booming.

Why should we care? Because immigrants are critical to the country's long-term economic health. Despite the fact that they constitute only 12% of the U.S. population, immigrants have started 52% of Silicon Valley's technology companies and contributed to more than 25% of our global patents. They make up 24% of the U.S. science and engineering workforce holding bachelor's degrees and 47% of science and engineering workers who have PhDs. Immigrants have co-founded firms such as Google (GOOG), Intel (INTC), eBay (EBAY), and Yahoo! (YHOO).
Who Are They? Young and Well-Educated

We tried to find hard data on how many immigrants had returned to India and China. No government authority seems to track these numbers. But human resources directors in India and China told us that what was a trickle of returnees a decade ago had become a flood. Job applications from the U.S. had increased tenfold over the last few years, they said. To get an understanding of how the returnees had fared and why they left the U.S., my team at Duke, along with AnnaLee Saxenian of the University of California at Berkeley and Richard Freeman of Harvard University, conducted a survey. Through professional networking site LinkedIn, we tracked down 1,203 Indian and Chinese immigrants who had worked or received education in the U.S. and had returned to their home countries. This research was funded by the Kauffman Foundation.

Our new paper, "America's Loss Is the World's Gain," finds that the vast majority of these returnees were relatively young. The average age was 30 for Indian returnees, and 33 for Chinese. They were highly educated, with degrees in management, technology, or science. Fifty-one percent of the Chinese held master's degrees and 41% had PhDs. Sixty-six percent of the Indians held a master's and 12.1% had PhDs. They were at very top of the educational distribution for these highly educated immigrant groups—precisely the kind of people who make the greatest contribution to the U.S. economy and to business and job growth.

Nearly a third of the Chinese returnees and a fifth of the Indians came to the U.S. on student visas. A fifth of the Chinese and nearly half of the Indians entered on temporary work visas (such as the H-1B). The strongest factor that brought them to the U.S. was professional and educational development opportunities.
