This chapter continues to build the argument that “being socially undocumented” entails having such a real and unique social identity. It argues that “being socially undocumented” is embodied. To make this argument, it first engages the narratives of socially undocumented people themselves as conveyed in the contexts of music, poetry, ethnographic interviews, and first-person testimonios in order to understand aspects of socially undocumented embodiment from the perspectives of those who experience it. Second, it traces the development of socially undocumented embodiment over the course of United States history, focusing on the Mexican-American war, the Treaty of Guadalupe-Hidalgo, the Johnson-Reed Act, Repatriation, and the Bracero Program. These explorations will reveal, it is argued, that socially undocumented embodiment is both racialized and class-based in nature. This means that “being socially undocumented” meets at least one of the criteria of a “visible” social identity identified in Chapter 2.
