The South American immigrant population in the United States has grown at a faster rate than that of the overall foreign-born population, amid crises in Venezuela, Colombia, and elsewhere. Yet South Americans still account for only about one in ten U.S. immigrants. While they mirror the overall U.S. immigrant population in several demographic characteristics, there are some notable differences, as this article details.
Hong Kong finds itself in the middle of opposing trends. Amid political unrest, Beijing's increasing security pressure, and pandemic disruptions, many Hong Kongers have left and been replaced by a new group of immigrants, largely from mainland China. The dynamic has raised questions whether Hong Kong will remain a global cosmopolitan hub or instead turn inward to Asia, as this article discusses.
The U.S. immigration enforcement system increasingly depends on other countries to help halt irregular movements through the Americas and accept the return of unauthorized migrants. Foreign governments play a crucial and yet underappreciated role in migration management, and can either aid or frustrate U.S. border-control aims, as this article explores.

Severe weather, rising seas, and other consequences of global climate change are affecting the way people live, work, and move around the planet. While there is no clear, direct line between the impacts of climate change and changing human movement, there are indications that the warming planet is indirectly creating or altering patterns of migration. Our podcast Changing Climate, Changing Migration dives deep into the intersection of climate change and migration to separate fact from fiction.

While smartphones and other technologies can assist decision-making, they do not always improve migrants’ journeys or lives. Forcibly displaced populations can face barriers in the form of limited internet access and low levels of digital literacy. Digital tools may also expose them to government surveillance and raise anxiety about social relations with loved ones. This article underscores refugees' complex relationships with technology.
Researchers often seek to predict how many people will move due to climate change, but beyond the inherent forecasting difficulties, their work is complicated by the fact that terms such as "climate migrant" are nebulous and migration drivers are often multifaceted. Instead, this article explains why analysts might ask how climate change will reshape existing patterns of migration and immobility.
Cerca de 855,000 inmigrantes colombianos residían en los Estados Unidos, lo que representa alrededor del 2 por ciento de los 45.3 millones de inmigrantes estadounidenses en general y el grupo más numeroso procedente de Sudamérica. Casi uno de cada cuatro inmigrantes de Sudamérica en los Estados Unidos procedía de Colombia.
Colombians comprise the largest group of South American immigrants in the United States. More than half live in Florida, New York, or New Jersey. Compared to the overall immigrant population, Colombians are disproportionately likely to be naturalized U.S. citizens and to have obtained a green card through family pathways.
The Haitian diaspora has swelled since a massive earthquake in 2010 and in the wake of violent riots that culminated in a political crisis in 2018 and the 2021 assassination of President Jovenel Moïse. Poverty, natural disasters, political crisis, and insecurity have historically driven Haitian migration. Destination countries have often rejected these arrivals and sought to deport Haitian migrants in large numbers.

Migrant millionaires are once again on the move, though headed to new destinations amid fallout from the COVID-19 pandemic and Russia's invasion of Ukraine. While wealthy new arrivals can help provide a healthy tax base and invest in local economies, they can upset housing markets and exacerbate wealth disparities, as this article describes.
Poland hosts millions of Ukrainians who fled Russia’s invasion. While the new arrivals have tended to have been greeted warmly, many have questions about the future. As the months pass, many displaced Ukrainians wonder when and if they will return to their native country. This article, based on interviews with dozens of displaced Ukrainians in Poland, examines their experiences.
Spain has an unconventional immigration system. The national government is primarily responsible for border control, granting legal status to migrants, and other issues, but integration is mostly handled by regional and local governments, allowing for some pioneering policies at the subnational level. This article explores what this system has meant for Catalonia and its capital, Barcelona, which have been considered to be a model throughout Europe.
Russia's invasion of Ukraine in 2022 ushered in renewed scrutiny of citizenship by investment programs, which allow wealthy Russian investors and others to become citizens of foreign countries. Some nations are now re-evaluating these "golden passport" schemes, which they developed to boost their economies. This article discusses the history of these programs and their evolution, why they have become controversial, and the main beneficiaries.
Romanians comprise the second largest immigrant community in Spain. This population grew at a dramatic rate during the early 2000s, driven by a variety of economic, policy, and other factors.

The end of the Vietnam war, marked by the fall of Saigon in 1975, precipitated the mass Indochinese refugee crisis, which saw more than 2 million people flee the region, often on unseaworthy boats. Following the war, Vietnamese migration was divided between humanitarian flows to the West, and labor migrants to allied communist countries. More recently, Vietnam's rapid economic growth has prompted increased labor migration to Asia and a rise in migrant brides.
This country profile analyzes Ecuador's migration trends and examines how remittances and return migration have become an important policy focus for a country with an estimated 1.5 million to 2 million nationals living abroad, chiefly in the United States, Spain, and Italy. As waves of emigration occurred, the country also has experienced significant inflows of refugees and economic and lifestyle migrants.

In the United States, Republicans and Democrats are deeply divided on immigration. President Donald Trump and Democratic presidential nominee Joe Biden have offered sharply diverging policy positions, and the outcome of the election is sure to have profound consequences for the U.S. immigration system. Yet this partisan divide is relatively new. Just two decades ago, the parties were much more united on immigrants’ role in the U.S. economy and society.
A looming furlough of 70 percent of staff at U.S. Citizenship and Immigration Services could halt processing for tens of thousands of green cards, citizenship applications, and other immigrant benefits each month it is in effect.

Calls by activists to "defund the police," in the wake of a string of deadly encounters for Black community members, echo earlier demands to "abolish ICE" and reflect broader criticism of enforcement systems perceived as overly aggressive. Budgets have ballooned at federal immigration agencies and within the immigrant detention system as enforcement has become increasingly muscular in the post-9/11 period.
The U.S. in April became the first country to explicitly justify immigration curbs not on grounds of COVID-19, but to protect the jobs of U.S. workers at a time of skyrocketing unemployment. A Trump administration proclamation limiting green cards for new arrivals was greeted coolly by the president's base, with many expecting the White House would issue new limits for nonimmigrant workers—which could have a more significant impact.
On the frontlines of responding to the COVID-19 pandemic yet also more disproportionately affected by the virus and with reduced health-care access, immigrants in the United States have largely found themselves blocked from federal economic relief.
