"Phi Hong Su's The Border Within is a game-changing book. Using rich ethnographic data with Vietnamese refugees and former contract workers in a reunified Berlin, Su paints a vivid portrait of how national and ethnic categories play out in everyday life. Avoiding simplistic conceptions of these categories, Su takes us into the lives of her subjects as they adopt and transform national and ethnic categories to draw lines of unity and division. This book is essential reading for anyone who hopes to understand how migration, war, and changing political boundaries influence belonging."

—Tomás R. Jiménez, co-author of States of Belonging

"A vivid account of Vietnamese border crossings – social, national, and political – that reconceptualizes the diaspora and notions of ethnonationalism. Su's remarkable study of the diverse pathways of Vietnamese migration to the once-divided city of Berlin serves as a poignant reminder of the ways in which Cold War divisions continue to shape daily lives and raise complex questions of belonging."

—Christina Schwenkel, author of Building Socialism

"In this remarkable book, Phi Hong Su poignantly analyzes what it means to be Vietnamese in the context of migration between two countries that were profoundly affected by war, national division, and reunification. Having originated decades ago, the Vietnamese community in Germany today continues to confront the impact of violence, division, and reunification on community, ethnic, national, and individual identities. Su deftly unpacks how discrepant histories of borders and border crossings within a coethnic migrant group shape ethnic nationalisms through social relationships and religious practices. The book makes a groundbreaking contribution to transnational studies of Asia and the Asian diaspora."

"The field of postcolonial studies has long been concerned with issues of cultural hybridity, national belonging, and political sovereignty. Phi Hong Su's The Border Within: Vietnamese Migrants Transforming Ethnic Nationalism in Berlin tackles all these weighty matters with a remarkable deftness that bridges divergent interests in decolonization, global migration, [and] the Cold War.... The Border Within is a major text for anyone who wishes to grasp the social forces that delimit postcolonial and diasporic identities. This important study reveals how nations are made, unmade, and remade with an understanding that the path to independence and freedom is riddled with endless controversy."

—Long T. Bui, Postcolonial Interventions

"Phi Hong Su asks a question of enduring interest to migration scholars and students of nationalism: How do ordinary people, thousands of miles from their homeland, make sense of their membership in a distant nation? Su adds two absorbing, creative wrinkles to this question by using a research design that sets The Border Within apart from prior scholarship...Su is both courageous and empathetic in the way she deals with the internal politics of the Vietnamese, their notions of ethnic nationalism, and their lives in Germany...These questions point to how fascinating and generative it is to read The Border Within."

—Irene Bloemraad, Social Forces

"...unusually theoretically sophisticated and analytically coherent.... The resulting book is as ambitious as it is humble: it shows a tremendous understanding of multiple national contexts and never makes grand claims that do not emerge from the data itself.... These arguments complement multiple fields of scholarship, including on the inadequacy of legal labels in capturing the true range of migration pathways and experiences; on taking categories, such as ethnicity, as to be explainedrather than explanatory; on immigrants as emigrants who continue to be impacted by their homelands; on the potential encumbrance of diasporic networks; on the lingering effects of the Cold War; and on how illuminating migrants' views onto receiving societies' histories can be.... Su's writing is unfailingly elegant, clear, and accessible."
