Ruth Gomberg-Munoz first book, Labor and Legality (2011), explores the lives of undocumented Mexicans living in Chicago. This book, Becoming Legal: Immigration Law and Mixed-Status Families (2017), explores the experiences of seeking legal status. The chapters follow the process, rooted in ethnographic research. The book is accessible. I used this book in a first-year undergraduate course and the content was well suited, particularly alongside some more theoretical readings. Recommended reading for those seeking an introduction to the use of ethnography and legal anthropology. 

I spent much of the summer looking for good ethnographies that would be suitable for first year undergraduate students - essentially a book that is not written for anthropologists, not heavy with theory, while still presenting the value that ethnography can offer. Gomberg-Munoz's Labor and Legality (2011) fit that well. The book also provides insight into a contemporary issues, which we encounter in our social media feeds and on the daily news, making it a book that can be quite engaging. If you are looking for an accessible ethnography on the topic of migration to the US (specifically, undocumented migration from Mexico), this is book well worth picking up. It is also quite useful as a book for teaching. Many of the ethnographies I read were more appropriate for graduate students and experts. Labor and Legality works well for a broader audience.
