Book excerpt: High-skilled immigrants are a very important component of U.S. innovation and entrepreneurship. Studies regarding the impact of immigrants on natives tend to find limited consequences in the short-run, while the results in the long-run are more varied and much less certain. Immigrants in the United States aid business and technology exchanges with their home countries, but the overall effect that the migration has on the home country remains unclear. Little is known about return migration of workers engaged in innovation and entrepreneurship, except that it is rapidly growing in importance.
