As host to more immigrants than any other country, the United States has been shaped and reshaped by immigration over the centuries, with the issue at times becoming a flashpoint. This article covers the history of U.S. immigration and the major laws governing immigration, and provides a comprehensive overview of the present-day immigrant population.

Migrants enrolled in the Migrant Protection Protocols are processed by U.S. Customs and Border Protection officers.

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.

Two boys pose in an informal settlement east of Johannesburg largely populated by immigrants.

South Africa hosts the most immigrants of any African country. Yet it faces conflicting pressures, including the legacy of apartheid, a steady outflow of well-educated South Africans, and the need to juggle bilateral labor mobility schemes at a time of economic insecurity and high unemployment.

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.

New Biden administration guidelines encourage immigration prosecutors to support dismissing many low-priority deportation cases and focus on criminals, threats to national security, and other priorities. This move could have a major impact on clearing backlogs in the overstretched U.S. immigration court system, resulting in quicker determinations in removal and asylum cases, where wait times can presently stretch for years.

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.
