"Immigration has deeply unsettled the taken-for-granted arrangements of western European societies and will change them almost beyond recognition during the course of this century. This cutting-edge collection of papers by leading scholars is essential reading for anyone who wants to understand the current situation and glimpse the possible roads ahead." - Richard Alba, co-editor, Germans or Foreigners "This is an unusually rich collection of essays that focus on the core problems of incorporation of immigrant communities in Western Europe. The editors have brought together a transatlantic group of authors that includes the best and most perceptive scholars now writing on questions of citizenship and incorporation." - Martin Schain, New York University
