Why did I love this book?
This is easily the best account of the complex, racialized history of U.S. immigration law, politics, and policy. One of the arguments in it that impressed me most is that the category “illegal aliens”—the “impossible subjects” of the title—barely existed in the pre-World War I years, when almost no European immigrants were turned away from the U.S. (Asians were another story). Ngai also brilliantly analyzes two landmark laws: the 1924 Johnson-Reed Act, which dramatically restricted immigration through nationality-based quotas limiting arrivals from Eastern and Southern Europe; and the 1965 Hart-Celler Act, which eliminated the quotas and opened the door to a massive new immigrant influx. This is a densely written book, not an easy read, but no other text has taught me more about this topic.
