Some of the most pressing questions in immigration law and policy today concern the problem of immigration controls. How are immigration laws administered, and how are they enforced against those who enter and remain in a receiving country without legal permission? Comparing the United States and Germany, two of the four extended essays in this volume concern enforcement; the other two address techniques for managing high-volume asylum systems in both countries.

As economic and military walls have come down in the post-Cold War era, states have rapidly built new barriers to prevent a perceived invasion of undesirables. This work examines the practice, politics, and consequences of building these walls.

Immigration is among the most prominent, enduring, and contentious features of our globalized world. Yet, there is little systematic, cross-national research on why countries "do what they do" when it comes to their immigration policies. Rights, Deportation, and Detention in the Age of Immigration Control addresses this gap by examining what are arguably the most contested and dynamic immigration policies—immigration control—across 25 immigrant-receiving countries, including the U.S. and most of the European Union. The book addresses head on three of the most salient aspects of immigration control: the denial of rights to non-citizens, their physical removal and exclusion from the polity through deportation, and their deprivation of liberty and freedom of movement in immigration detention. In addition to answering the question of why states do what they do, the book describes contemporary trends in what Tom K. Wong refers to as the machinery of immigration control, analyzes the determinants of these trends using a combination of quantitative analysis and fieldwork, and explores whether efforts to deter unwanted immigration are actually working.

The migration movements of the 20th century have led to an increased interest in similarly dramatic population changes in the preceding century. The contributors to this volume - legal scholars, sociologists, political scientist and historians - focus on migration control in the 19th century, concentrating on three areas in particular: the impact of the French Revolution on the development of modern citizenship laws and on the development of new forms of migration control in France and elsewhere; the theory and practice of migration control in various European states is examined, focusing on the control of paupers, emigrants and "ordinary" travelers as well as on the interrelationship between the different administrative levels - local, regional and national - at which migration control was exercised. Finally, on the development of migration control in two countries of immigration: the United States and France. Taken altogether, these essays demonstrate conclusively that the image of the 19th century as a liberal era during which migration was unaffected by state intervention is untenable and in serious need of revision.

A critical assessment of border controls in twentieth-century Europe that puts forward the case for their abolition.

Us and Them? explores the distinction between migrant and citizen through using the concept of 'the community of value'. The challenges of migration go to the heart of equality, rights, freedom, and membership. These are not only matters for migrants but go to the heart of citizens' politics.
