In today's knowledge-based economy, capturing value from intellectual capital and knowledge-based assets has gained importance. Global competition is no longer for the control of raw materials, but for this productive knowledge. This paper is the third in a series of studies focusing on immigrants' contributions to the competitiveness of the U.S. economy. Earlier research revealed a dramatic increase in the contributions of foreign nationals to U.S. intellectual property over an eight-year period. In this paper, we offer a more refined measure of this change and seek to explain this increase with an analysis of the immigrant-visa backlog for skilled workers. The key finding from this research is that the number of skilled workers waiting for visas is significantly larger than the number that can be admitted to the United States. This imbalance creates the potential for a sizeable reverse brain-drain from the United States to the skilled workers' home countries. This research was supported by the Kauffman Foundation.
