In this illuminating work, immigrant rights activist Aviva Chomsky shows how illegality and undocumentedness are concepts that were created to exclude and exploit. With a focus on US policy, she probes how people, especially Mexicans and Central Americans, have been assigned this status-and to what ends. Blending history with human drama, Chomsky explores what it means to be undocumented in a legal, social, economic, and historical context. The result is a powerful testament of the complex, contradictory, and ever-shifting nature of status in America.
