Initially targeting Chinese women, immigration control based on sexuality rapidly expanded to encompass every woman who sought entry to the United States. The particular cases Luibheid examines -- efforts to differentiate Chinese prostitutes from wives, the 1920s exclusion of Japanese wives to reduce the Japanese-American birthrate, the deportation of a Mexican woman on charges of lesbianism, the role of rape in mediating women's border crossings today -- challenge conventional accounts that attribute exclusion solely to prejudice or lack of information. This innovative work clearly links sexuality-based immigration exclusion to a dominant nationalism premised on sexual, gender, racial, and class hierarchies.
