Funds from this grant will provide support for a major conference on high-skilled immigration for both researchers and non-specialists. Organized by Stephen Merrill, Executive Director of the Board on Science, Technology, and Economic Policy of that National Academy of Sciences, the conference will concentrate on international comparisons of policies that influence the supply, demand, and mobility of scientists and engineers. An expert committee appointed by STEP, will study this topic in advance of the conference and commission several review papers. Subsequent to the conference, the Academy will issue a peer-reviewed publication featuring feature conference session summaries, the commissioned papers, and a research agenda that can help prioritize future work in this area.
