More PhD's head home after graduation in the US

Readers of my editorials might recall my Feb. 21 column which quoted Vivek Wadhwa, Executive in Residence at Duke University, as warning that more and more PhD's head back to their own countries after getting their degree in the US. His warning is true, according to the Chronicle of Higher Education.

The problem is that foreign PhD's are also some of the of the most innovative, at least according to Wadhwa. So their skills and abilties migrate elsewhere to countries that, in turn, compete with the US.
