Losing Our Edge is an article written by Thomas Friedman and appeared in the NY Times. Thanks to Signor Ferrari who suggested the link. Here's a bit:
Other executives complained bitterly that the Department of Homeland Security is making it so hard for legitimate foreigners to get visas to study or work in America that many have given up the age-old dream of coming here. Instead, they are studying in England and other Western European nations, and even China. This is leading to a twofold disaster.
First, one of America's greatest assets — its ability to skim the cream off the first-round intellectual draft choices from around the world and bring them to our shores to innovate — will be diminished, and that in turn will shrink our talent pool. And second, we could lose a whole generation of foreigners who would normally come here to study, and then would take American ideas and American relationships back home. In a decade we will feel that loss in America's standing around the world.
