[Excerpt] Congress has an ongoing interest in regulating the immigration of professional, managerial, and skilled foreign workers to the United States. This workforce is seen by many as a catalyst of U.S. global economic competitiveness and is likewise considered a key element of the legislative options aimed at stimulating economic growth. The challenge central to the policy debate is facilitating the migration of professional, managerial, and skilled foreign workers without adversely affecting U.S. workers and U.S. students entering the labor market. This report opens with an overview of the policy issues. It follows with a summary of each of the various visa categories available for temporary professional, managerial, and skilled foreign workers as well as an analysis of the trends in the use of these various visas over the past two decades. The policy of authorizing foreign students to work in the United States for at least a year following graduation is discussed next. The labor market tests for employers hiring temporary foreign workers are also summarized. The rules regarding federal taxation of professional, managerial, and skilled foreign workers are explained. The report concludes with a discussion of the avenues for professional, managerial, and skilled foreign workers to become legal permanent residents (LPRs) in the United States.
