Medical Transnationalism examines Korean immigrants' distinctive healthcare behaviors, contributing factors to their medical tourism, and their experiences and evaluations of medical tourism. Analyzing survey data of 507 Korean immigrants and in-depth interviews with 120 Korean immigrants in the New York-New Jersey area, this book finds that there are three distinctive types of healthcare behaviors that Korean immigrants employ to deal with their barriers (e.g., the language barrier and not having health insurance) to formal US healthcare: dependence on co-ethnic doctors in the United States, the use of Hanbang (traditional Korean medicine) in the United States, and medical tours to the homeland. This book also finds that social transnational ties and health insurance status are the most influential contributing factors to Korean immigrants' decision to take medical tours to the home country. The vast majority of Korean immigrant medical tourists are satisfied with their medical tourism experiences. In this book, Sou Hyun Jang makes both empirical and theoretical contributions to the literature on immigrant healthcare and immigrant transnationalism by focusing on one immigrant group and connecting medical transnationalism to other types of transnationalism. The findings of this book imply that health programs for the most marginalized group-small business owners and their employees-and better support for bilingual Korean-English translators at hospitals are needed.
