The Takeaway
The STEM OPT visa extension provided empirical evidence against the common belief that foreign talent crowds out domestic workers. This policy change directly led to a boom in innovation as more immigrants were able to patent their ideas and contribute to the economy. The arrival of these new inventors did not replace the work of native-born scientists. Instead, it grew the total pool of research and development in the United States. This research shows that the labor market is not a zero-sum game where one person's gain is another's loss. Immigration policy can be a powerful engine for technological growth that benefits everyone.
From the abstract
Can foreign students at U.S. universities, with a brief work extension, become inventors without displacing native talent? This paper examines one of the most significant recent U.S. immigration policy changes, the 2008 STEM Optional Practical Training extension, which gives international STEM graduates an additional 17 months of work authorization. I show a 60%-86.8% increase in the number of first-time immigrant inventors and a 17.6%-23.4% increase in the share of first-time immigrant inventor
