Immigration and refugee policies have traditionally been based on two assumptions: first, that national sovereignty implies absolute control of a country's borders and, second, that outsiders are to be admitted only when it serves the national interest. Moral or ethical concerns have not played a central role in policy formation anywhere in the world. This collection of essays challenges the traditional politically oriented position, analyzes the moral issues involved, and develops models for morally responsible immigration and refugee policies in a contemporary political setting. The editor's introduction reviews the history of U.S. immigration policy and provides a framework for considering immigration control issues. Written by leading authorities on immigration and refugee policy, this provocative volume offers an honest, sensitive exploration of some of the most difficult questions facing contemporary society. It will be of interest for studies in ethics, human rights, public policy, and political economy, as well as to general readers concerned with immigration and refugee issues.
