Just as the US tightens immigration controls, a huge backlog in processing visas for legal migrants is causing a "reverse brain drain," forcing sought-after scientists, engineers, doctors and entrepreneurs to return to their home countries, according to a report released yesterday. One million would-be immigrants are competing for only 120,000 permanent visas issued each year, reports AFP.
"The US benefits from having foreign-born innovators create their ideas in this country. Their departures would be detrimental to US economic well-being," said the co-author of the report. Nearly a third of US tech start ups are launched by immigrants, and more than half of the companies in Silicon Valley were founded by foreigners.
