The ease of transportation, the opening of international immigration policies, the growing refugee movements, and the increasing size of unauthorized immigrant populations suggest that immigration worldwide is a phenomenon of utmost importance to professionals who develop policies and programs for, or provide services to, immigrants. Immigration occurs in both the wealthy nations of the global North and the poorer countries of the global South; it involves individuals who arrive with substantial human capital and those with little. It has far-reaching implications for a nation's economy, public policies, social and health services, and culture. The purpose of this volume, therefore, is to explore current patterns and policies of immigration in key countries and regions across the globe and analyze the implications for these countries and their immigrant populations. Each of its chapters, written by an international and interdisciplinary group of experts, explores how country conditions, policies, values, politics, and attitudes influence the process of immigration and subsequently affect immigrants, migration, and the nation itself. No other volume explores the landscape of worldwide immigration as broadly as this does, with sweeping coverage of countries and empirical research, together with an analytic framework that sets the context of human migration against a wide backdrop of experiential factors that take shape long before an immigrant enters a host country.
