A valuable resource for high school, college, and general readers, this book provides an up-to-date, comprehensive examination of illegal immigration in America, addressing its complex history, comparing its occurrence today with the past, and explaining why a solution is so difficult to enact. Who is coming into the United States illegally and why? What compels people to leave their country of origin? Is the United States responsible for taking care of the more than 11 million individuals who are here illegally? Are illegal immigrants helping or harming our nation's economy and infrastructure? Should our borders be "secured" as called for by many politicians? This book examines the history of illegal immigration in the United States, addressing the tough questions about the issue and describing in detail the most significant issues and events in recent decades. It succinctly tackles the topic of illegal immigration without bias, explores the myriad of problems and controversies that have arisen due to illegal immigration, and explains how lawmakers have historically tried-and continue to try-to solve these issues. This thoroughly revised and updated second edition of Illegal Immigration: A Reference Handbook covers the debate over the vexing and seemingly intractable illegal immigration problem from all angles and updates the discussion to 2015. It covers the key court, executive, and legislative-branch actions on the matter and examines both state and national-level government attempts to cope with illegal immigration. The book also contains a variety of primary source documents in summary format that cover all the key laws enacted, presidential or state governor's executive actions taken, and key court decisions since 1985. These documents not only provide factual data but also give context that allows readers to better grasp the complexity of the problem and the difficulty in trying to improve the situation through regulation.
