Book excerpt: The most comprehensive collection of essays on undocumented immigration to date, covering issues not generally found anywhere else on the subject. Three fascinating volumes feature the latest research from the country's top immigration scholars. In the United States, the crisis of undocumented immigrants draws strong opinions from both sides of the debate. For those who immigrate, concerns over safety, incorporation, and fair treatment arise upon arrival. For others, the perceived economic, political, and cultural impact of newcomers can feel threatening. In this informative three-volume set, top immigration scholars explain perspectives from every angle, examining facts and seeking solutions to counter the controversies often brought on by the current state of undocumented immigrant affairs. Immigration expert and set editor Lois Lorentzen leads a stellar team of contributors, laying out history, theories, and legislation in the first book; human rights, sexuality, and health in the second; and economics, politics, and morality in the final volume. From family separation, to human trafficking, to notions of citizenship, this provocative study captures the human costs associated with this type of immigration in the United States, questions policies intended to protect the "American way of life," and offers strategies for easing tensions between immigrants and natural-born citizens in everyday life.
