Immigration to the United States has been a major source of population growth and cultural change throughout much of its history. In absolute numbers, the United States has by far the highest number of immigrants in the world, with 50,661,149 people as of 2019. This represents 19.1% of the 244 million international migrants worldwide, and 14.4% of the United States' population. In 2018, there were almost 90 million immigrants and U.S.-born children of immigrants in the United States, accounting for 28% of the overall U.S. population.
The Immigration and Nationality Act of 1965, also known as the Hart–Celler Act and more recently as the 1965 Immigration Act, is a landmark federal law passed by the 89th United States Congress and signed into law by President Lyndon B. Johnson. The law abolished the National Origins Formula, which had been the basis of U.S. immigration policy since the 1920s. The act formally removed de facto discrimination against Southern and Eastern Europeans as well as Asians, in addition to other non-Western and Northern European ethnicities from the immigration policy of the United States.
Immigration reduction refers to a government and social policy in the United States that advocates a reduction in the amount of immigration allowed into the country. Steps advocated for reducing the numbers of immigrants include advocating stronger action to prevent illegal entry and illegal migration, and reductions in non-immigrant temporary work visas. Some advocate tightening the requirements for legal immigration requirements to reduce numbers, or move the proportions of legal immigrants away from those on family reunification programs to skills-based criteria.
The Center for Immigration Studies (CIS) is an American anti-immigration think tank. It favors far lower immigration numbers and produces analyses to further those views. The CIS was founded by historian Otis L. Graham and eugenicist and white nationalist John Tanton in 1985 as a spin-off of the Federation for American Immigration Reform (FAIR). It is one of a number of anti-immigration organizations founded by Tanton, along with FAIR and NumbersUSA.
Immigration is the international movement of people to a destination country of which they are not usual residents or where they do not possess nationality in order to settle as permanent residents. Commuters, tourists, and other short-term stays in a destination country do not fall under the definition of immigration or migration; seasonal labour immigration is sometimes included, however.
Foreign nationals (aliens) can violate US immigration laws by entering the United States unlawfully or lawfully entering but then remaining after the expiration of their visas, parole, or temporary protected status. Illegal immigration has been a matter of intense debate in the United States since the 1980s.
Illegal immigration is the migration of people into a country in violation of that country's immigration laws, or the continuous residence in a country without the legal right to. Illegal immigration tends to be financially upward, from poorer to richer countries. Illegal residence in another country creates the risk of detention, deportation, and/or other sanctions.

The Coalition for Humane Immigrant Rights, also known as CHIRLA, is a Los Angeles county-based organization focusing on immigrant rights. While the organization did evolve from a local level, it is now recognized at a national level. The Coalition for Humane Immigrant Rights of Los Angeles organizes and serves individuals, institutions and coalitions to build power, transform public opinion, and change policies to achieve full human, civil and labor rights. The Coalition for Humane Immigrant Rights of Los Angeles also has aided in passing new laws and policies to benefit the immigrant community regardless of documented status.
Immigration and crime refers to the relationship between criminal activity and the phenomenon of immigration. The academic literature and official statistics provide mixed findings for the relationship between immigration and crime. Research in the United States tends to suggest that immigration either has no impact on the crime rate or even that immigrants are less prone to crime. A meta-analysis of 51 studies from 1994–2014 on the relationship between immigration and crime in the United States found that, overall, the immigration-crime association is negative, but the relationship is very weak and there is significant variation in findings across studies. This is in line with a 2009 review of high-quality studies conducted in the United States that also found a negative relationship.
The Southern Africa region experiences a relatively high influx of immigration into South Africa. As of 2019, the immigration rate is continuing to increase, and the role of the female population of migrants is significantly growing in this movement and settlement. The majority of immigrants are working residents and influence the presence of several sectors in South Africa. The demographic background of this group is diverse, and the countries of origin mainly belong to Sub-Saharan Africa and push migration south. A portion have qualified as refugees since the 1990s.
The United States government holds tens of thousands of immigrants in detention under the control of Customs and Border Protection and the Immigration and Customs Enforcement (ICE). Immigrants are detained for unlawful entry to the United States, when their claims for asylum are received, and in the process of deportation and removal from the country. During Fiscal Year 2018, 396,448 people were booked into ICE custody: 242,778 of whom were detained by CBP and 153,670 by ICE's own enforcement operations. A daily average of 42,188 immigrants were held by ICE in that year. In addition, over twelve thousand immigrant children are housed by facilities under the supervision of the Office of Refugee Resettlement's program for Unaccompanied Alien Children. Prior to referral to these other agencies, the CBP holds immigrants at processing centers; between mid-May and mid-June 2019, it held between 14,000 and 18,000 immigrants.

The 2014 American immigration crisis was a surge in unaccompanied children and women from the Northern Triangle of Central America (NTCA) seeking entrance to the United States in 2014. According to U.S. law, an unaccompanied alien child refers to a person under 18 years of age, who has no lawful immigration status in the U.S., and who does not have a legal guardian to provide physical custody and care.
The National Immigration Law Center (NILC) is a center in the United States that "engages in policy analysis, litigation, education and advocacy, to achieve [the] vision" of "a society in which all people—regardless of race, gender, immigration or economic status—are treated fairly and humanely." They claim to concentrate on social, economic, and racial justice for low-income immigrants. They have offices in Washington, D.C. as well as in Los Angeles and Oakland, California. Their executive director is Marielena Hincapié.
Immigration policy, including illegal immigration to the United States, was a signature issue of former U.S. president Donald Trump's presidential campaign, and his proposed reforms and remarks about this issue generated much publicity. Trump has repeatedly said that illegal immigrants are criminals.
Federal policy oversees and regulates immigration to the United States and citizenship of the United States. The United States Congress has authority over immigration policy in the United States, and it delegates enforcement to the Department of Homeland Security. Historically, the United States went through a period of loose immigration policy in the early-19th century followed by a period of strict immigration policy in the late-19th and early-20th centuries. Policy areas related to the immigration process include visa policy, asylum policy, and naturalization policy. Policy areas related to illegal immigration include deferral policy and removal policy.
Joe Biden's immigration policy is primarily based on reversing many of the immigration policies of the previous Trump administration. During his first day in office, Biden reversed many of Trump's policies on immigration, such as halting the construction of the Mexican border wall, ending Trump's travel ban restricting travel from 14 countries, and an executive order to reaffirm protections for DACA recipients. The Biden administration and Department of Homeland Security, under leadership of Alejandro Mayorkas, dramatically reined in deportation practices of Immigration and Customs Enforcement (ICE), prioritizing national security and violent crime concerns over petty and nonviolent offenses. However, Biden has also faced criticism for extending Title 42, a Trump administration border restriction that arose due to the COVID-19 pandemic, as well as restarting the use of expediting families in Central America, which can cause families to be sent back in weeks, compared to years for an average immigration case. In the fiscal year 2021, the US Border Patrol confirmed more than 1.6 million encounters with migrants along the US-Mexico border, more than quadruple the number in the previous fiscal year and the largest annual total on record. In January 2023, Biden announced a program to strengthen the admission of immigrants from Cuba, Haiti, Nicaragua, and Venezuela, while at the same time his administration will crack down on those who fail to use the plan's legal pathway and strengthen border security. In May 2023, the Biden Administration approved sending 1,500 more troops to the U.S.-Mexico border following Title 42's expiration.
Immigration to the United States has many effects on the culture and politics of the United States.
