Partners in Gatekeeping is an important contribution to U.S. immigration historiography. Braun-Strumfel’s use of Italian sources offers a powerful sense of how immigration to the United States played on both sides of the Atlantic at the policy level, correcting the prevailing notion that restrictionism developed almost wholly in the context of anti-Asian sentiments.

Partners in Gatekeeping relies on exciting, innovative, and ambitious research. The amount of never-before-used primary sources (at least in U.S. history) is breathtaking and one of the book’s many strengths. . . . With this evidentiary base, Braun-Strumfels clarified questions I have long had. She also raised questions that had not even occurred to me to ask, but were lightbulb moments as I read them.
