About the Book:Most policy books confine their historical discussions to a relatively short time frame. This book offers a long-term historical analysis of American immigration policy. From Open Door to Dutch Door details current policy and its shortcomings. In addition, the book describes the four distinct phases of U.S. immigration policy since 1820, why these shifts occurred, and their impact on decisions being made today. Written in a clear and readable style, the book combines a historical approach with an assessment of a timely and topical area of public policy.
