How did Gomberg-Muñoz become interested in this project? What are her two primary arguments in the book? How is this fieldwork different from typical anthropological ethnography fieldwork (especially consider legal status and ethnography within U.S.)? What ethical dilemmas does the author face? Why does she spend time in both the preface and chapter 1 discussing terminology used in the book? What is the braceros program? How does globalization influence undocumented migration? Why is this answer more complex than just, “migrants come here for jobs?”
