"The United States Code is the official codification of the general and permanent laws of the United States of America. The Code was first published in 1926, and a new edition of the code has been published every six years since 1934. The 2012 edition of the Code incorporates laws enacted through the One Hundred Twelfth Congress, Second Session, the last of which was signed by the President on January 15, 2013. It does not include laws of the One Hundred Thirteenth Congress, First Session, enacted between January 2, 2013, the date it convened, and January 15, 2013. By statutory authority this edition may be cited "U.S.C. 2012 ed." As adopted in 1926, the Code established prima facie the general and permanent laws of the United States. The underlying statutes reprinted in the Code remained in effect and controlled over the Code in case of any discrepancy. In 1947, Congress began enacting individual titles of the Code into positive law. When a title is enacted into positive law, the underlying statutes are repealed and the title then becomes legal evidence of the law. Currently, 26 of the 51 titles in the Code have been so enacted. These are identified in the table of titles near the beginning of each volume. The Law Revision Counsel of the House of Representatives continues to prepare legislation pursuant to 2 U.S.C. 285b to enact the remainder of the Code, on a title-by-title basis, into positive law. The 2012 edition of the Code was prepared and published under the supervision of Ralph V. Seep, Law Revision Counsel. Grateful acknowledgment is made of the contributions by all who helped in this work, particularly the staffs of the Office of the Law Revision Counsel and the Government Printing Office"--Preface.

What does it mean to be an American? The United States defines itself by its legal freedoms; it cannot tell its citizens who to be. Nevertheless, where possible, it must separate citizen from alien. In so doing, it defines the desirable characteristics of its citizens in immigration policy, spelling out how many and, most importantly, what sorts of persons can enter the country with the option of becoming citizens. Over the past century, the U.S. Congress argued first that prospective citizens should be judged in terms of race, then in terms of politics, then of ideology, then of wealth and skills. Each argument arose in direct response to a perceived foreign threat--a threat that was, in the government's eyes, racial, political, ideological, or economic. Immigration and the Politics of American Sovereignty traces how and why public arguments about immigrants changed over time, how some arguments came to predominate and shape policy, and what impact these arguments have had on how the United States defines and defends its sovereignty. Cheryl Shanks offers readers an explanation for immigration policy that is more distinctly political than the usual economic and cultural ones. Her study, enriched by the insights of international relations theory, adds much to our understanding of the notion of sovereignty and as such will be of interest to scholars of international relations, American politics, sociology, and American history. Cheryl Shanks is Assistant Professor of Political Science, Williams College.

Few issues on the American political agenda are more complex or divisive than immigration. There is no shortage of problems with current policies and practices, from the difficulties and delays that confront many legal immigrants to the large number of illegal immigrants living in the country. Moreover, few issues touch as many areas of U.S. domestic life and foreign policy. Immigration is a matter of homeland security and international competitiveness, as well as a deeply human issue central to the lives of millions of individuals and families. It cuts to the heart of questions of citizenship and American identity and plays a large role in shaping both America's reality and its image in the world. Immigration's emergence as a foreign policy issue coincides with the increasing reach of globalization. Not only must countries today compete to attract and retain talented people from around the world, but the view of the United States as a place of unparalleled openness and opportunity is also crucial to the maintenance of American leadership. There is a consensus that current policy is not serving the United States well on any of these fronts. Yet agreement on reform has proved elusive. The goal of the Independent Task Force on U.S. Immigration Policy was to examine this complex issue and craft a nuanced strategy for reforming immigration policies and practices.
