The author, writing from pastoral experience in New York City, offers a practical introduction to recent arrivals by defining terms, surveying motives and numbers, and profiling four major immigrant groups encountered in urban ministry. Chapters explore everyday life, cultural differences, and the roots of prejudice while presenting institutions and programs that aid assimilation and welfare. Emphasis falls on habits of neighborliness—education, companionship, and organized outreach—followed by discussions of helpful versus harmful responses from hosts and a closing appeal for civic responsibility and broader international understanding.
