This course examines circumstances that facilitate or hinder the political, social, and economic incorporation of immigrants. In addition to reviewing early twentieth-century sociological theories of immigration, the course analyzes contemporary research on immigration from the standpoint of political science and related disciplines. While focused primarily on explaining patterns by which immigrants are incorporated in the United States and Europe, it also compares cases from Latin America, Eurasia, the Middle East, and other regions in relation to shared or dissimilar immigration policies, levels of economic development, and demographic compositions.
