Operation Allies Refuge was an evacuation effort carried out by the United States during the 2021 Taliban offensive. It took place in the final weeks of the War in Afghanistan and saw the airlifting of certain at-risk Afghan civilians (particularly coalition-allied interpreters), employees of the American embassy in Kabul, and other prospective applicants for the U.S. Special Immigrant Visa (SIV). American personnel also helped NATO and other regional allies in their respective evacuation efforts from Hamid Karzai International Airport in the capital city of Kabul. The operation was concurrent with the broader American military withdrawal from Afghanistan and the multinational evacuation of eligible foreigners and vulnerable Afghans.
SIV applicants were airlifted to the U.S., where they were temporarily housed by the American military while they completed their SIV requirements.
Immigration has been a major source of population growth and cultural change in the United States throughout much of its history. As of January 2025, the United States has the largest immigrant population in the world in absolute terms, with 53.3 million foreign-born residents, representing 15.8% of the total U.S. population—both record highs. While the United States represented about 4% of the total global population in 2024, 17% of all international migrants resided in the United States. In March 2025, the Federation for American Immigration Reform (FAIR) estimated that approximately 18.6 million illegal immigrants resided in the United States. In 2024, immigrants and their U.S.-born children number more than 93 million people, or 28% of the total U.S. population.According to the 2016 Yearbook of Immigration Statistics, the United States admitted a total of 1.18 million legal immigrants (618k new arrivals, 565k status adjustments) in 2016. Of these, 48% were the immediate relatives of United States citizens, 20% were family-sponsored, 13% were refugees or asylum seekers, 12% were employment-based preferences, 4.2% were part of the Diversity Immigrant Visa program, 1.4% were victims of a crime (U1) or their family members were (U2 to U5), and 1.0% who were granted the Special Immigrant Visa (SIV) for Iraqis and Afghans employed by the United States Government. The remaining 0.4% included small numbers from several other categories, including 0.2% who were granted suspension of deportation as an immediate relative of a citizen (Z13); persons admitted under the Nicaraguan and Central American Relief Act; children born after the issuance of a parent's visa; and certain parolees from the former Soviet Union, Cambodia, Laos, and Vietnam who were denied refugee status.
Between 1921 and 1965 policies such as the National Origins Formula limited immigration and naturalization opportunities for people from areas outside Northwestern Europe. Exclusion laws enacted as early as the 1880s generally prohibited or severely restricted immigration from Asia, and quota laws enacted in the 1920s curtailed Southern and Eastern European immigration. The civil rights movement led to the replacement of these ethnic quotas with per-country limits for family-sponsored and employment-based preference visas. Between 1970 and 2007, the number of first-generation immigrants living in the United States quadrupled from 9.6 million to 38.1 million residents. Census estimates show 45.3 million foreign born residents in the United States as of March 2018 and 45.4 million in September 2021, the lowest three-year increase in decades.
Afghans in Pakistan are migrants from Afghanistan—some of whom are registered in Pakistan as refugees and asylum seekers. The United Nations High Commissioner for Refugees (UNHCR) provides limited protection to them. Many of them were born and raised in Pakistan during the last four decades. Additionally, there are also Special Immigrant Visa applicants awaiting to immigrate to the United States.
The Pakistani government began admitting Afghans after the beginning of the Soviet–Afghan War in 1979; by the end of 2001, there were over four million of them on the Pakistani side. While some have returned to Afghanistan many decided to stay in Pakistan.
