This paper studies the impact of U.S. immigration barriers on global knowledge production. We present four key findings. First, among Nobel Prize winners and Fields Medalists, migrants to the U.S. play a central role in the global knowledge network—representing 20-33% of the frontier knowledge producers. Second, using novel survey data and hand-curated life-histories of International Math Olympiad (IMO) medalists, we show that migrants to the U.S. are up to six times more productive than migrants to other countries—even after accounting for talent during one’s teenage years. Third, financing costs are a key factor preventing foreign talent from migrating abroad to pursue their dream careers, particularly for talent from developing countries. Fourth, certain ‘push’ incentives that reduce immigration barriers—by addressing financing constraints for top foreign talent—could increase the global scientific output of future cohorts by 42 percent. We concludeby discussing policy options for the U.S. and the global scientific community.

The story of West Indian immigrants to the United States is generally considered to be a great success. Mary Waters, however, tells a very different story. She finds that the values that gain first-generation immigrants initial success--a willingness to work hard, a lack of attention to racism, a desire for education, an incentive to save--are undermined by the realities of life and race relations in the United States. Contrary to long-held beliefs, Waters finds, those who resist Americanization are most likely to succeed economically, especially in the second generation.

The Economic and Fiscal Consequences of Immigration finds that the long-term impact of immigration on the wages and employment of native-born workers overall is very small, and that any negative impacts are most likely to be found for prior immigrants or native-born high school dropouts. First-generation immigrants are more costly to governments than are the native-born, but the second generation are among the strongest fiscal and economic contributors in the U.S. This report concludes that immigration has an overall positive impact on long-run economic growth in the U.S. More than 40 million people living in the United States were born in other countries, and almost an equal number have at least one foreign-born parent. Together, the first generation (foreign-born) and second generation (children of the foreign-born) comprise almost one in four Americans. It comes as little surprise, then, that many U.S. residents view immigration as a major policy issue facing the nation. Not only does immigration affect the environment in which everyone lives, learns, and works, but it also interacts with nearly every policy area of concern, from jobs and the economy, education, and health care, to federal, state, and local government budgets. The changing patterns of immigration and the evolving consequences for American society, institutions, and the economy continue to fuel public policy debate that plays out at the national, state, and local levels. The Economic and Fiscal Consequences of Immigration assesses the impact of dynamic immigration processes on economic and fiscal outcomes for the United States, a major destination of world population movements. This report will be a fundamental resource for policy makers and law makers at the federal, state, and local levels but extends to the general public, nongovernmental organizations, the business community, educational institutions, and the research community.

In 2006, the United Nations reported on the “feminization” of migration, noting that the number of female migrants had doubled over the last five decades. Likewise, global awareness of issues like human trafficking and the exploitation of immigrant domestic workers has increased attention to the gender makeup of migrants. But are women really more likely to migrate today than they were in earlier times? In Gender and International Migration, sociologist and demographer Katharine Donato and historian Donna Gabaccia evaluate the historical evidence to show that women have been a significant part of migration flows for centuries. The first scholarly analysis of gender and migration over the centuries, Gender and International Migration demonstrates that variation in the gender composition of migration reflect not only the movements of women relative to men, but larger shifts in immigration policies and gender relations in the changing global economy. While most research has focused on women migrants after 1960, Donato and Gabaccia begin their analysis with the fifteenth century, when European colonization and the transatlantic slave trade led to large-scale forced migration, including the transport of prisoners and indentured servants to the Americas and Australia from Africa and Europe. Contrary to the popular conception that most of these migrants were male, the authors show that a significant portion were women. The gender composition of migrants was driven by regional labor markets and local beliefs of the sending countries. For example, while coastal ports of western Africa traded mostly male slaves to Europeans, most slaves exiting east Africa for the Middle East were women due to this region’s demand for female reproductive labor. Donato and Gabaccia show how the changing immigration policies of receiving countries affect the gender composition of global migration. Nineteenth-century immigration restrictions based on race, such as the Chinese Exclusion Act in the United States, limited male labor migration. But as these policies were replaced by regulated migration based on categories such as employment and marriage, the balance of men and women became more equal – both in large immigrant-receiving nations such as the United States, Canada, and Israel, and in nations with small immigrant populations such as South Africa, the Philippines, and Argentina. The gender composition of today’s migrants reflects a much stronger demand for female labor than in the past. The authors conclude that gender imbalance in migration is most likely to occur when coercive systems of labor recruitment exist, whether in the slave trade of the early modern era or in recent guest-worker programs. Using methods and insights from history, gender studies, demography, and other social sciences, Gender and International Migration shows that feminization is better characterized as a gradual and ongoing shift toward gender balance in migrant populations worldwide. This groundbreaking demographic and historical analysis provides an important foundation for future migration research.

The market for high-skilled workers is becoming increasingly global, as are the markets for knowledge and ideas. While high-skilled immigrants in the United States represent a much smaller proportion of the workforce than they do in countries such as Australia, Canada, and the United Kingdom, these immigrants have an important role in spurring innovation and economic growth in all countries and filling shortages in the domestic labor supply. This report summarizes the proceedings of a Fall 2014 workshop that focused on how immigration policy can be used to attract and retain foreign talent. Participants compared policies on encouraging migration and retention of skilled workers, attracting qualified foreign students and retaining them post-graduation, and input by states or provinces in immigration policies to add flexibility in countries with regional employment differences, among other topics. They also discussed how immigration policies have changed over time in response to undesired labor market outcomes and whether there was sufficient data to measure those outcomes.

Few issues on the American political agenda are more complex or divisive than immigration. There is no shortage of problems with current policies and practices, from the difficulties and delays that confront many legal immigrants to the large number of illegal immigrants living in the country. Moreover, few issues touch as many areas of U.S. domestic life and foreign policy. Immigration is a matter of homeland security and international competitiveness, as well as a deeply human issue central to the lives of millions of individuals and families. It cuts to the heart of questions of citizenship and American identity and plays a large role in shaping both America's reality and its image in the world. Immigration's emergence as a foreign policy issue coincides with the increasing reach of globalization. Not only must countries today compete to attract and retain talented people from around the world, but the view of the United States as a place of unparalleled openness and opportunity is also crucial to the maintenance of American leadership. There is a consensus that current policy is not serving the United States well on any of these fronts. Yet agreement on reform has proved elusive. The goal of the Independent Task Force on U.S. Immigration Policy was to examine this complex issue and craft a nuanced strategy for reforming immigration policies and practices.

A sweeping narrative history of American immigration from the colonial period to the present "A masterly historical synthesis, full of wonderful detail and beautifully written, that brings fresh insights to the story of how immigrants were drawn to and settled in America over the centuries."--Nancy Foner, author of One Quarter of the Nation The history of the United States has been shaped by immigration. Historians Carl J. Bon Tempo and Hasia R. Diner provide a sweeping historical narrative told through the lives and words of the quite ordinary people who did nothing less than make the nation. Drawn from stories spanning the colonial period to the present, Bon Tempo and Diner detail the experiences of people from Europe, Asia, Africa, and the Americas. They explore the many themes of American immigration scholarship, including the contexts and motivations for migration, settlement patterns, work, family, racism, and nativism, against the background of immigration law and policy. Taking a global approach that considers economic and personal factors in both the sending and receiving societies, the authors pay close attention to how immigration has been shaped by the state response to its promises and challenges.

The global race for talent is on, with countries and businesses competing for the best and brightest. Talented individuals migrate much more frequently than the general population, and the United States has received exceptional inflows of human capital. This foreign talent has transformed U.S. science and engineering, reshaped the economy, and influenced society at large. But America is bogged down in thorny debates on immigration policy, and the world around the United States is rapidly catching up, especially China and India. The future is quite uncertain, and the global talent puzzle deserves close examination. To do this, William R. Kerr uniquely combines insights and lessons from business practice, government policy, and individual decision making. Examining popular ideas that have taken hold and synthesizing rigorous research across fields such as entrepreneurship and innovation, regional advantage, and economic policy, Kerr gives voice to data and ideas that should drive the next wave of policy and business practice. The Gift of Global Talent deftly transports readers from joyous celebrations at the Nobel Prize ceremony to angry airport protests against the Trump administration's travel ban. It explores why talented migration drives the knowledge economy, describes how universities and firms govern skilled admissions, explains the controversies of the H-1B visa used by firms like Google and Apple, and discusses the economic inequalities and superstar firms that global talent flows produce. The United States has been the steward of a global gift, and this book explains the huge leadership decision it now faces and how it can become even more competitive for attracting tomorrow's talent.

Since 1965 the foreign-born population of the United States has swelled from 9.6 million or 5 percent of the population to 45 million or 14 percent in 2015. Today, about one-quarter of the U.S. population consists of immigrants or the children of immigrants. Given the sizable representation of immigrants in the U.S. population, their health is a major influence on the health of the population as a whole. On average, immigrants are healthier than native-born Americans. Yet, immigrants also are subject to the systematic marginalization and discrimination that often lead to the creation of health disparities. To explore the link between immigration and health disparities, the Roundtable on the Promotion of Health Equity held a workshop in Oakland, California, on November 28, 2017. This summary of that workshop highlights the presentations and discussions of the workshop.
