Through a sociological analysis of Hmong former refugees' grassroots movements in the United States between the 1990s and 2000s, Immigrant Agency shows how Hmong, despite being one of America's most economically impoverished ethnic groups, were able to make sustained claims on and have their interests represented in public policies. The author, Yang Sao Xiong argues that the key to understanding how immigrants incorporate themselves politically is to understand how they mobilize collective action and make choices in circumstances far from racially neutral. Immigrant groups, in response to political threats or opportunities or both, mobilize collective action and make strategic choices about how to position themselves vis-à-vis other minority groups, how to construct group identities, and how to deploy various tactics in order to engage with the U.S. political system and influence policy. In response to immigrants' collective claims, the racial state engages in racialization which undermines immigrants' political standing and perpetuates their marginalization.
