"This is one of those books that you wish you could get everyone to read. ... For classes that focus on questions of global migration, political belonging and exclusion, and the powers of the State, this book is a useful resource. Rich in historical facts that help explain how we have reached a point where citizenship often overshadows humanity, Citizenship in Question will be a valuable addition for a required reading list or a personal library. Essential."- M. Lecea (Choice) "[A] remarkable contribution that both adds to scholarship on citizenship and challenges some of the inherent assumptions that underpin citizenship studies. ... This sophisticated and wide-ranging volume is essential reading for not only those interested in citizenship, bureaucracy and the state, but also for a wider, non-academic audience." - Kalathmika Natarajan (LSE Review of Books) “The case studies in this volume present a significant human rights challenge. . . . Citizenship allocations may seem as neatly drawn as lines on the map of the world. As this volume demonstrates, there are many contexts in which they are hardly that.” - Peter J. Spiro (Perspectives on Politics) "Powerful. . . . The contributing authors show through numerous examples how citizenship is not self-evident, nor can it be inferred from documents alone, which is another fundamental paradox to citizenship." - Sue-Je Lee Gage (PoLAR) "Essential reading for academics in citizenship law, but also a broader audience grappling with what citizenship and belonging mean in a modern world." - Susi Foerschler (Border Criminologies)
