Debating Immigration presents 18 original essays, written by some of the world's leading experts and pre-eminent academics, that explore the nuances of contemporary immigration and citizenship affecting the United States and Europe. The volume is organized around the following themes: religion and philosophy, law and policy, economics and demographics, race and ethnicity, and cosmopolitanism. Critical questions addressed include: What accounts for the disconnect between public attitudes about immigration and the policies produced by elected officials? Why has the United States not developed a well-articulated public philosophy of immigration? What does the Christian Bible have to say about immigration policy? What are our moral and social obligations to our fellow citizens, and do these trump our obligations to the world's poor? How does the European experience differ from the American situation?
