Sarah R. Coleman, "The Walls Within: The Politics of Immigration in Modern America" (Princeton UP, 2023)

Sarah Coleman, an historian at Texas State University, is the author of an important and topical book about immigration policy in the United States. The Walls Within: The Politics of Immigration in Modern America (Princeton UP, 2023) focuses much less on the often-discussed physical border between the United States and other countries, and more so on the internal touchpoints where immigration federalism takes place. Coleman does a number of things in this book, including providing a fascinating overview of immigration policies and prohibitions throughout U.S. history, but not in a linear mode—instead, she integrates the historical record into the discussion of the domestic policies that were developed over the past 70 years.

Sifting through demographic changes, economic shifts, congressional legislation, and court challenges, Coleman weaves together the different policies and outcomes, and the different forms of enforcement. This is what contributes to immigration federalism, since restrictions, prohibitions, and denial of opportunities generally happen at a state or local level. Thus, where immigration policy is actually touching people—citizens and non-citizens alike—is not, per se, where a Border Control officer exam
