Natalia Molina is Associate Dean for Faculty Equity, Division of Arts and Humanities, and Associate Professor of History and Urban Studies at the University of California, San Diego. In this presentation of her new book, she will examine the experience of Mexican Americans—from 1924, when American law drastically reduced immigration into the United States, to 1965, when many quotas were abolished—to understand how broad themes of race and citizenship are constructed. These years shaped the emergence of what Professor Molina describes as an immigration regime, which defined the racial categories that continue to influence perceptions in the United States about Mexican Americans, race, and ethnicity.
