While I don't agree with everything the author of this Washington Post article writes, the numbers and his bottom line estimate are accurate and scary.

The timing of the immigration battles couldn’t be worse. Just as China has become the second-largest economy in the world and India follows on its heels to become number three, their best and the brightest are losing interest in coming to the U.S. Immigrant entrepreneurs and foreign engineering students—who receive 60 percent of America’s engineering Ph.D.s and 40 percent of its master’s—are headed home.

There are several reasons why they head home, but a major player is the fact that it's becoming increasingly difficult for them to stay legally.  This is really bad for America now, but it promises to get worse.

Given America’s history, these findings are devastating. Over the past four decades, graduates of the top Indian and Chinese engineering colleges flocked to the U.S. to launch their careers, and many stayed and started tech companies. My research team documented that, from 1995 to 2005, foreign-born workers founded 52 percent of Silicon Valley’s startups. In 2006, foreign nationals residing in the U.S contributed to 26 percent of America’s global patents. One in four doctors in the U.S. are foreign-born, as are nearly half of all scientists and engineers who have a doctorate.

America is in desperate need of an economical boost.  We need more companies, more employers, more innovation and as anyone who needs medical care knows, more doctors!  America needs to return to its capitalist roots and embrace the immigrant, for more reasons than one.
