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 Mexican 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.
