abstract: This project examines the decision of American policymakers to deny the Amerasians of Vietnam--the offspring of American fathers and Vietnamese mothers born as a result of the Vietnam War--American citizenship in the 1982 Amerasian Immigration Act and the 1987 Amerasian Homecoming Act. It investigates why policymakers deemed a population unfit for the responsibilities of American society, despite the fact that they had American fathers. The examination draws upon numerous archival collections of the key policymakers, humanitarians and non-governmental organizations involved in each piece of legislation. Additionally, archival and published documents from the U.S. government and military, popular media, and veteran's organizations, are important. Since many of those involved in the legislation are still living, oral history interviews are also a critical piece of the methodology. The dissertation argues that the exclusion of citizenship was a component of bigger issues: international relationships in a Cold War era, America's defeat in the Vietnam War, and a history in the United States of racialized exclusionary immigration and citizenship policies against people of Asian descent. It exposes the contradictory approach of policymakers unable to reconcile the Amerasian mixture of race and nation with US law. Consequently, policymakers simultaneously employed an inclusionary discourse that deemed the Amerasians worthy of American attention, guidance and humanitarian aid, and implemented exclusionary policies that designated them unfit for the responsibilities of American citizenship. / Dissertation/Thesis / Doctoral Dissertation History 2015
