The Immigration Act of 1924 shaped the U.S. population over the course of the 20th century, greatly restricting immigration and ensuring that arriving immigrants were mostly from Northern and Western Europe. The century-old law was one of the most restrictive in U.S. history and helped create the framework for key provisions of the U.S. immigration system that remain in place a century later. This article analyzes the effect and legacy of the 1924 law.

Immigrants have served in the U.S. armed forces since the nation's founding. In recent years, a growing share of U.S. military veterans are immigrants, due to shrinking numbers of veterans overall and a rising number of foreign born. This article offers details about the composition of the immigrant population with U.S. military service.

In recent decades, countries worldwide have expanded voting rights to their diasporas as well as certain resident noncitizens. Voting access in general has grown over time, as barriers based on sex, literacy, and other characteristics have fallen, and migrants' increasingly expansive rights to vote are part of that trend worldwide. This article provides a global overview of the dynamics.

Once an obscure section of U.S. law, Title 42 was used to expel unauthorized migrants reaching U.S. borders nearly 3 million times from March 2020 to May 2023. Despite idealized depictions of its impact by some politicians, the order was largely ineffective in deterring irregular migration. Instead, it represented a dramatic break with decades of law providing protection to asylum seekers, as this article details.

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.

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.

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.

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.
