Global talent pool and student migration to the U.S.

A fresh study looks at the central role of American universities and companies in advancing scientific knowledge worldwide through migration patterns and barriers. With 4% of the world’s population, the U.S. is the site of 20-33% of “frontier knowledge producers.” Migrants to the U.S. account for one in five worldwide Nobel Prize winners in science. Much of the world’s top talent migrates to the U.S. but only some eventually return to their countries of origin.

The U.S. is so important for global scientific advances that by removing barriers to American education, global scientific output of talent would increase by 42%.

Migrants to the U.S. are significantly more productive than migrants to other countries. Migrants to the U.S. are four to six times more productive than those staying in their country of origin. Educational financing costs are a key factor preventing foreign talent to migrate to the U.S. Among International student math gold medalists in developing counties, 66% dream of studying in the U.S. while only 25% manage to do so. The key constraint is not immigration policy but lack of financing of an American education.
