The United States is once again in the midst of a peak period of immigration. By 2005, more than 35 million legal and illegal migrants were present in the United States. At different rates and with differing degrees of difficulty, a great many will be incorporated into American society and culture. Leading immigration experts in history, sociology, anthropology, economics, and political science here offer multiethnic and multidisciplinary perspectives on the challenges confronting immigrants adapting to a new society. How will these recent arrivals become Americans? Does the journey to the U.S. demand abandoning the past? How is the United States changing even as it requires change from those who come here? Broad thematic essays are coupled with case studies and concluding essays analyzing contemporary issues facing Muslim newcomers in the wake of 9/11. Together, they offer a vibrant portrait of America's new populations today.Contributors: Anny Bakalian, Elliott Barkan, Mehdi Bozorgmehr, Caroline Brettell, Barry R. Chiswick, Hasia Diner, Roland L.
