Marisa Abrajano examines whether landmark immigration events can leave a permanent mark on an individual's views towards immigration, and whether that impact varies across different racial and ethnic groups. Specifically, the author, examines the cohort of individuals who were in their formative years during the passage of major national immigration bills that were proposed or enacted from 1965-2010. Her findings indicate a clear and consistent relationship between these events and attitudes toward social groups; a less systemic relationship emerges between these policy events and attitudes on immigration policies. She prossess recommendations to policy makers and community advocates about how to leverage these findings into action.
