Immigration, as a conduit for bringing new talent, ideas, and inventions into the United States, is essential to the success and vitality of our economy and society. In this timely book, researched and written by the Immigration Book Project Team at Penn State University, immigration is approached from historical, economic, business, and sociological perspectives in order to argue that treatment of immigrants must reflect and applaud their critical roles in supporting and leading the economic, social, cultural, and political institutions of civil society. Approaching immigration as both a socioeconomic phenomenon and a matter of public policy, this book offers demographics and statistics on workforce participation and job creation along with stories of individual immigrants' contributions to the economy and society. It supports the idea that, when immigration is challenged in the political sphere, we must not lose sight of the valuable contributions that immigrants have made-and will continue to make-to our democracy.
