This study has been discussed here before:

I have read the entire paper and still feel that all of these studies miss one very important point. They all assume that all graduates from United States schools are U.S. Citizens and go on to contribute to the U.S. workforce. Have you seen the student makeup at U.S. Universities in the past 10-20 years? The number of foreign nationals attending U.S. universities seems (to me) to be very high. Even when I was in school 20 years ago the number of foreign nationals in my classes was alarming. Most of these foreign nationals are here paid for by either a company or their government to study here and return to their country to work. I am trying to put this delicately without offending anyone here. I don't know of many American students that are filling up the universities in India and China but the reverse seems to be common. While it is true that the U.S. may graduate as many or more engineers and scientists per capita as India and China are they all staying here and contributing to the U.S. workforce? That is the study I would like to read.
