Migration can help build resilience against the encroaching effects of climate change. Instead of being passive victims of environmental degradation, individuals sometimes move to gain money, knowledge, and skills that can fortify their household of origin. Migrant workers from Thailand demonstrate how and under what conditions this process works.

Despite a widespread perception that the Trump administration has drastically slashed legal immigration to the United States, a review of the data shows that temporary and permanent admissions during the period mostly followed previous trends—at least until the COVID-19 pandemic hit. This article examines trends in temporary, permanent, and humanitarian admissions during the administration, and the related policies that could take a more significant bite ahead if left unchanged.

The nearly 11 million Mexican immigrants in the United States represent almost one-quarter of the country’s entire immigrant population, and as such are the largest foreign-born group. But their numbers have been declining, shrinking by 7 percent between 2010 and 2019. Among recently arrived immigrants, those from China and India now outpace Mexicans for the first time.

Before entering office, President Donald Trump promised to deport millions of unauthorized immigrants. Yet despite his general successes in creating a more restrictive and punitive immigration system, this goal has eluded his administration. So-called “sanctuary” policies implemented by state and local governments to limit their cooperation with U.S. Immigration and Customs Enforcement have been a key reason why arrests and removals have not reached earlier peaks.

Climate change is affecting human movement now, causing internal displacement and international migration, and will do so in the future. But the impact is often indirect, and rarely is the process as straightforward as one might think. This article provides an overview of research on how climatic hazards drive and affect migration, reviewing which types of people might migrate and under what conditions.

Health-care workers

Immigrants make up a disproportionately high number of U.S. health-care workers, from doctors and nurses to home health aides. In 2018, more than 2.6 million immigrants worked in the U.S. health-care field. In the face of the coronavirus pandemic, immigrants have played a key role in the frontline response. This article explores the demographics of this group of essential workers by occupation, origin, language, education, and more.

Border closures and lockdowns amid the COVID-19 pandemic have put a chill on intra-EU labor mobility, most immediately with the difficulty for European farmers to gain access to much-needed seasonal workers and for health-care institutions to get care workers. This article explores how these workers, who often face difficult situations, may be more vulnerable now. It also takes on implications for intra-EU labor mobility post-pandemic.

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. As states and philanthropic groups seek to plug the gap, this article examines conditions and changing policies around immigration and the coronavirus response.

Five years after Russia's annexation of Crimea, displaced Ukrainians continue to face challenges related to national identity, social cohesion, and political participation. While the Ukrainian government has had some success integrating IDPs, the conflict’s end remains uncertain, and many are unlikely to return to their communities of origin no matter the outcome.

Authoritarian states have long attempted to restrict citizens’ movement. But what happens when their reach extends beyond their borders? The October 2018 assassination of Saudi journalist Jamal Khashoggi brought into sharp relief the long arm of these regimes in reaching citizens abroad. This phenomenon, “transnational authoritarianism,” further shows that the relationship between migration and authoritarianism is becoming more complex.

European immigrants in the United States have largely dwindled in number since 1960, after historically making up the bulk of immigration to the country. Today, immigrants from Eastern Europe account for the largest share of European arrivals, and Europeans overall are much older and more educated than the total foreign- and native-born populations. This article explores the data on Europeans in the United States.

Morocco has evolved into one of the world’s leading emigration countries. European immigration restrictions did not stop migration, but rather pushed Moroccan migrants into permanent settlement, prompting large-scale family reunification. Morocco is also becoming a destination country, and the growing presence of immigrants confronts Moroccan society with an entirely new set of social and legal issues typical for immigration countries, as this country profile explores.

Economic turmoil has been a primary driver of emigration from The Gambia, located in West Africa and the smallest country on the African continent.

Travel ban protest at the Supreme Court

Though the Supreme Court handed the Trump administration a major victory by upholding its much-contested travel ban, less noted has been the fact that the ruling left an opening for future challenges to the policy of barring groups of foreign nationals from the country. This Policy Beat explores the evolution of the travel ban, the justices' arguments for and against, and changes in visa grants from travel-ban countries.

Frustrated by an uptick in migrant apprehensions at the U.S.-Mexico border in recent months, the Trump administration unveiled a set of sweeping changes, aiming to prosecute for federal immigration crimes every migrant apprehended crossing illegally. The policy will likely be hindered by legal challenges and capacity limitations, as this article explores.

Troops at the border

Seizing on reports of a migrant “caravan” making its way northward through Mexico, President Donald Trump called for up to 4,000 National Guard troops to deploy to the Southern border. Although previous presidents took similar action in response to upticks in violence and apprehensions, the picture at the border today differs on several metrics. This article examines how the deployment compares to those under Presidents George W. Bush and Barack Obama.

While much attention has focused on President Trump's efforts to crack down on illegal immigration, the administration has moved, via a much wider scope of actions, to reduce legal immigration to the United States. This article explores changes including slowed processing of family- and employment-based visas, dramatic cuts in refugee admissions, and heightened vetting and evidence requirements for would-be immigrants.

Department of Justice

The Trump administration has been steadily building a case to penalize "sanctuary" cities—those jurisdictions that in some way limit their cooperation with federal immigration authorities—after threatening to cut federal funding. Despite court rulings that seemed to strike a blow against these efforts, the Justice Department is moving forward with its strategy, relying on a broad interpretation of a federal statute, as this article explores.
