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.
Emigration is the act of leaving a resident country or place of residence with the intent to settle elsewhere. Conversely, immigration describes the movement of people into one country from another. A migrant emigrates from their old country, and immigrates to their new country. Thus, both emigration and immigration describe migration, but from different countries' perspectives.
The libertarian perspective on immigration is often regarded as one of the core concepts of libertarian theory and philosophy. There is considerable disagreement among libertarians as to what stance towards immigration best accords with libertarian principles. Some hold that restrictions on immigration are an infringement of the rights of immigrants and other property owners and constitute a threat to individual liberty. Others maintain that open borders amount to a policy of forced integration on the part of the state, and that protecting the rights of property holders requires that present governments adopt much more discriminatory policies on who is allowed to enter a country.
Human migration is the movement of people from one place to another, with intentions of settling, permanently or temporarily, at a new location. The movement often occurs over long distances and from one country to another, but internal migration is the dominant form of human migration globally.
An asylum seeker is a person who leaves their country of residence, enters another country, and makes in that other country a formal application for the right of asylum according to the Universal Declaration of Human Rights Article 14. A person keeps the status of asylum seeker until the right of asylum application has concluded.
The Immigration Act of 1924, or Johnson–Reed Act, including the Asian Exclusion Act and National Origins Act, was a United States federal law that prevented immigration from Asia and set quotas on the number of immigrants from Eastern and Southern Europe. It also authorized the creation of the country's first formal border control service, the U.S. Border Patrol, and established a "consular control system" that allowed entry only to those who first obtained a visa from a U.S. consulate abroad.
Freedom of movement, mobility rights, or the right to travel is a human rights concept encompassing the right of individuals to travel from place to place within the territory of a country, and to leave the country and return to it. The right includes not only visiting places, but changing the place where the individual resides or works.
Immigration law includes the national statutes, regulations, and legal precedents governing immigration into and deportation from a country. Strictly speaking, it is distinct from other matters such as naturalization and citizenship, although they are sometimes conflated. Countries frequently maintain laws that regulate both the rights of entry and exit as well as internal rights, such as the duration of stay, freedom of movement, and the right to participate in commerce or government.
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.
Opposition to immigration, also known as anti-immigration, is a political ideology that seeks to restrict immigration. In the modern sense, immigration refers to the entry of people from one state or territory into another state or territory in which they are not citizens. Illegal immigration occurs when people immigrate to a country without having official permission to do so. Opposition to immigration ranges from calls for various immigration reforms, to proposals to completely restrict immigration, to calls for repatriation of existing immigrants.
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 do so. Illegal immigration tends to be financially upward, from poorer to richer countries. Illegal residence in another country creates the risk of detention, deportation, and other imposed sanctions.
Immigration to Greece percentage of foreign populations in Greece is 7.1% in proportion to the total population of the country. Moreover, between 9 and 11% of the registered Greek labor force of 4.4 million are foreigners. Migrants additionally make up 25% of wage and salary earners.
Immigration to Malaysia is the process by which people migrate to Malaysia to reside in the country. The majority of these individuals become Malaysian citizens. After 1957, domestic immigration law and policy went through major changes, most notably with the Immigration Act 1959/63. Malaysian immigration policies are still evolving.
An open border is a border that enables free movement of people between jurisdictions with no restrictions on movement and is lacking substantive border control. A border may be an open border due to intentional legislation allowing free movement of people across the border, or a border may be an open border due to a lack of legal controls, a lack of adequate enforcement or adequate supervision of the border. An example of the former is the Schengen Agreement between most members of the European Economic Area. An example of the latter has been the border between Bangladesh and India, which is becoming controlled. The term "open borders" applies only to the flow of people, not the flow of goods and services, and only to borders between political jurisdictions, not to mere boundaries of privately owned property.

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.
A migrant crisis is a difficult or dangerous situation that arises due to the movements of large groups of immigrants in the receiving state. Migrants are often escaping from conditions which negatively affected them in the country of origin (departure). The "crisis" is not the amount of refugees, but the system's failure to respond in an orderly way to the government's legal obligations towards them. Some notable crises are; European migrant crisis, English Channel migrant crisis and World War II evacuation and expulsion.
Immigration to the United States has many effects on the culture and politics of the United States.
Externalization describes the efforts of wealthy, developed countries to prevent asylum seekers and other migrants from reaching their borders, often by enlisting third countries or private entities. Externalization is used by Australia, Canada, the United States, the European Union and the United Kingdom. Although less visible than physical barriers at international borders, externalization controls or restricts mobility in ways that are out of sight and far from the country's border. Examples include visa restrictions, sanctions for carriers that transport asylum seekers, and agreements with source and transit countries. Consequences often include increased irregular migration, human smuggling, and border deaths.
Discrimination based on nationality is discriminating against a person based on their nationality, country of citizenship, or national origin. Although many countries' non-discrimination laws contain exceptions for nationality and immigration status, nationality is related to race and religion, so direct discrimination on the basis of nationality may be indirect discrimination on racial or religious grounds. The International Convention on the Elimination of All Forms of Racial Discrimination (CERD), currently signed by 88 countries, allows discrimination by nationality, citizenship or naturalization but prohibits discrimination "against any particular nationality".
