Requirements that international travelers and migrants prove vaccination against certain diseases are about as old as vaccines themselves. In some cases, vaccine certificates predated the existence of government-issued passports. This article explores the history of these requirements, which began with smallpox and have since been applied for diseases including cholera, polio, yellow fever, and, recently, COVID-19.

The United States’ controversial Title 42 migrant expulsions policy will come to an end in May 2022, after more than 1.7 million expulsions over two years. The COVID-19-era public-health restriction ushered in an unprecedented period of mass expulsions, including of would-be asylum seekers, at the U.S.-Mexico border. Unwinding the policy will be complicated amid predictions of a significant increase in unauthorized migration.

This article offers insights about rates of poverty, health insurance, and other metrics for Black immigrants both nationally and in the top five major cities of residence, finding that policies at federal and local levels, as well as the legacy of historical Black disenfranchisement, can exaggerate or reduce some of the gaps with U.S.-born White residents.

Migration from the Middle East and North Africa (MENA) region to the United States doubled between 2000 and 2019, yet these immigrants represented less than 3 percent of the overall U.S. foreign-born population as of 2019. MENA immigrants are more likely than other immigrants to be English proficient, have a college degree, and work in management, business, science, and arts occupations.
More than half of all immigrants in the United States are naturalized citizens. The number of new naturalizations has fluctuated from year to year, hitting a decade-long low in fiscal year 2020, in part due to the COVID-19 pandemic and rising processing times.

With nearly 18 million nationals abroad, India is the origin of more international migrants than any other country and claims the world's largest diaspora. Indian emigration can be traced back to the colonial era, with the British empire dispatching Indian workers across the globe, and has evolved for more than a century in response to global labor demands and geopolitical events. This article offers a comprehensive profile of migration from and to India.
China has a long history of international migration. Movement was sharply interrupted following the 1949 revolution but has rebounded in recent decades. Since 1979, the country has developed from one of mostly limited migration into one that is in many ways defined through its global interactions, although it continues to treat migration warily, as this country profile explains.

President Joe Biden has made efforts to overhaul the U.S. immigration system, but could see his administration's agenda slowed by massive backlogs across the immigration system. Case application wait times and immigration court queues have swelled during the COVID-19 pandemic, slowing legal arrivals to the United States and undermining the entire immigration system.
While Donald Trump’s presidency is perceived as being the most active on immigration, touching nearly every aspect of the U.S. immigration system, President Joe Biden’s administration has far outpaced his predecessor in the number of executive actions taken during his first year in office—even as the pace of change has gone largely unnoticed, as this article explores.
The Biden administration's court-ordered restart of the controversial Migrant Protection Protocols, known informally as the Remain in Mexico policy, puts it in the awkward position of reviving a program it is simultaneously still trying to end. The Trump-era program forced tens of thousands of migrants to wait out the duration of their U.S. immigration court hearings in Mexico and was only questionably successful at deterring unauthorized arrivals.
U.S. immigration arrests have declined to the lowest level in years. Going forward, new U.S. Immigration and Customs Enforcement guidelines could further shape how authorities arrest and deport unauthorized immigrants and noncitizens who have committed crimes. This article describes how the Biden administration prosecutorial discretion guidance marks a sharp turn from the approach taken by the Trump administration.
