There is general agreement today that traditional approaches to immigration admissions in the major receiving countries of the West have serious shortcomings either in concept or implementation, or at times in both. These essays, all written by leading immigration experts, consider the philosophical and moral constraints on immigration law and policy, the basic elements of a comprehensive migration policy, and specific policy areas, including family reunification and asylum. Taken together, these perspectives represent a fresh, comparative look at some of the most urgent issues in this pivotal area of law and policy.

Hiroshi Motomura has been a professor of law at the University of Colorado School of Law in Boulder since 1982. Before that, he was an attorney in Washington, D.C., with a practice that included immigration law matters. He writes and lectures extensively on immigration law and policy topics, with an emphasis on constitutional issues. Publications include the law school casebook Immigration: Policy and Process (with T. Alexander Aleinikoff and David A. Martin; 3d ed. 1995) and the articles "The Curious Evolution of Immigration Law: Procedural Surrogates for Substantive Constitutional Rights" (Columbia Law Review 1992) and "Immigration Law after a Century of Plenary Power: Phantom Constitutional Norms and Statutory Interpretation" (The Yale Law Journal 1990).
