'This pioneering book offers one of the first systematic comparative studies of immigration and citizenship regimes in Japan, South Korea, and Taiwan. Erin Aeran Chung unpacks both the structural similarities among the three cases and their surprising divergences in the 2000s. Chung demonstrates how civil society and preexisting patterns of civic legacies explain how Korea has changed more than Japan, and why Taiwan has liberalized the least. This is a must-read book for students of migration studies and those interested in the politics and societies of Japan, Korea, and Taiwan.' Yves Tiberghien, University of British Columbia
