Peter Kwong, professor of Asian American studies and urban affairs and planning at Hunter College, spoke in Sanders Auditorium on illegal Chinese immigrants in the United States.  Professor Kwong’s research in Forbidden Workers:  Illegal Chinese Immigrants and American Labor (1999)—interviews with immigrant workers, their families in China, activists, Chinese-American bosses and human smugglers—was regarded as a most reliable guide to a startling instance of “modern slavery” in America.
