Who controls American immigration policy? The biggest immigration controversies of the last decade have all involved policies produced by the President policies such as President Obama's decision to protect Dreamers from deportation and President Trump's proclamation banning immigrants from several majority-Muslim nations. While critics of these policies have been separated by a vast ideological chasm, their broadsides have embodied the same widely shared belief: that Congress, not the President, ought to dictate who may come to the United States and who will be forced to leave. This belief is a myth. In The President and Immigration Law, Adam B. Cox and Cristina M. Rodríguez chronicle the untold story of how, over the course of two centuries, the President became our immigration policymaker-in-chief. Diving deep into the history of American immigration policy from founding-era disputes over deporting sympathizers with France to contemporary debates about asylum-seekers at the Southern border they show how migration crises, real or imagined, have empowered presidents. Far more importantly, they also uncover how the Executive's ordinary power to decide when to enforce the law, and against whom, has become an extraordinarily powerful vehicle for making immigration policy. This pathbreaking account helps us understand how the United States ?has come to run an enormous shadow immigration system-one in which nearly half of all noncitizens in the country are living in violation of the law. It also provides a blueprint for reform, one that accepts rather than laments the role the President plays in shaping the national community, while also outlining strategies to curb the abuse of law enforcement authority in immigration and beyond.

National identity cards are in the news. While paper ID documents have been used in some countries for a long time, today's rapid growth features high-tech IDs with built-in biometrics and RFID chips. Both long-term trends towards e-Government and the more recent responses to 9/11 have prompted the quest for more stable identity systems. Commercial pressures mix with security rationales to catalyze ID development, aimed at accuracy, efficiency and speed. New ID systems also depend on computerized national registries. Many questions are raised about new IDs but they are often limited by focusing on the cards themselves or on "privacy." Playing the Identity Card shows not only the benefits of how the state can "see" citizens better using these instruments but also the challenges this raises for civil liberties and human rights. ID cards are part of a broader trend towards intensified surveillance and as such are understood very differently according to the history and cultures of the countries concerned.
