History of US ImmigrationWhile Indigenous peoples predated Europeans in the region by thousands of years, colonial settlers mainly came from Britain and Western Europe, some of whom brought, or bought, enslaved Africans. Later waves brought Irish, German, and Chinese immigrants in the mid-19th century, followed by a large influx from southern and Eastern Europe between 1880 and 1920. Immigration slowed afterward due to restrictive laws that set quotas based on national origin.
The Immigration and Nationality Act of 1965 ended the national-origins quota system that favored Europeans, allowing more immigrants from Asia, Africa, and Latin America—an outcome its own sponsors did not predict. Immigration is the main driver of US population growth, accounting for 84% of the nation's increase from July 2023 to July 2024. Immigrants generated about $1.7T in economic activity in 2023. As of June 2025, 51.9 million immigrants lived in the United States, representing 15.4% of the total population.
Enforcement of immigration laws today mainly falls to the Department of Homeland Security and its subagencies—Customs and Border Protection, US Citizenship and Immigration Services, and Immigration and Customs Enforcement—which use physical barriers, deportations, and interior enforcement to regulate immigration. Today, individuals can legally immigrate to the United States through family sponsorship or employment-based visas, or by seeking asylum or refugee status. Immigration has become a key issue in US politics after record border encounters from 2021 to 2024, followed by aggressive enforcement policies during President Donald Trump's second term.
