"A lively and learned exploration of dual nationality and its future. Professor Spiros book illuminates the forces that make the spread of dual nationality seem inevitable, and the advantages it provides both to individuals and to states. His telling examples humanize the subject, but he also conveys eloquently how globalization dilutes older ideals of citizenship." - Gerald L. Neuman,J. Sinclair Armstrong Professor of International, Foreign, and Comparative Law, Harvard University "Peter Spiro has been the leading scholar of dual citizenship for more than two decades, and he has prophetically linked its rise to still more far-reaching transformations in the global system of nation-states and nation-state citizenship. This provocative yet engaging work is a major statement that will inform and influence citizenship scholarship and political debates for many years to come." - Rogers M. Smith,Christopher H. Brwne Distinguished Professor of Political Science, University of Pennsylvania "Peter Spiro's erudite and crisply written book on dual citizenship will help any reader better understand business and life generally in the global economy. The definitive work on its topic, At Home in Two Countries deserves a broad audience. It will provoke important debate." - Paul M. Barrett,Senior Writer, Bloomberg Businessweek "Spiros book makes an important contribution to the study of citizenship in general and of dual citizenship in particular." (International Migration Review) "In this timely, historical-analytical explication, Spiro expertly explains the provocative concept of dual citizenship." (Choice Connect)
