Temporary migrants to the United States, known legally as non-immigrants, have grown in number and importance over the 1980s and 1990s. The Immigration Act of 1990 in particular instituted a number of changes that the U.S. Commission on Immigration Reform is evaluating for its final report to Congress in 1997. This volume represents a significant contribution to the fact-finding efforts undertaken by the Commission to understand the implementation and impact of these policies. Scholars and policymakers working in the immigration arena have long appreciated the complexity of the different categories of permanent admissions, but only now are they turning their attention to the oftentimes linked temporary system with its rather different complexities. In this volume, leading scholars examine the non-immigrant system's major visa categories for temporary workers and foreign students. The Commission solicited these authors' contributions to help the Commission identify major policy issues and their solutions. The introductory chapter summarizes the authors' observations and recommendations on a range of topics, from the overall system of non-immigrant admissions to the effects of specific visa categories on U.S. businesses and workers, as well as our universities and students. The chapters here, comprising one of the first collections of scholarly studies on the topic, offer considerable scope and a solid point of departure for policymakers evaluating the non-immigrant system.
