|Legal status of persons|
Different countries use varying terms for "aliens" including:
- an illegal immigrant, illegal alien or undocumented alien is person who is residing on a non-temporary basis in a country where he or she has no legal right to reside. It is a non-citizen who has entered a country through illegal migration, for example entered illegally, or an alien who entered a country legally but who has fallen "out of status", and subsequently refused to leave the country as legally required, or a descendant of one.
- a legal alien is a non-citizen who is legally permitted to remain in a country. This is a very broad category which includes tourists, guest workers, legal permanent residents and student visa resident aliens.
- an enemy alien is a non-citizen who is a national of an enemy country.
Common law jurisdictions
An "alien" in English law was someone who was born outside of the monarch's dominions and who did not have allegiance to the monarch. Aliens were not allowed to own land and were subject to different taxes to subjects. This idea was passed on in the Commonwealth to other common law jurisdictions.
In Australia, citizenship is defined in the Australian nationality law. Non-citizens living in Australia are either permanent residents; temporary residents; or illegal residents (technically called "unlawful non-citizens"). Most non-citizens (including those who lack citizenship documents) travelling to Australia must obtain a visa prior to travel. The only exceptions to this rule are holders of New Zealand passports and citizenship who may apply for a visa on arrival according to the Trans-Tasman Travel Arrangement.
In Canada, the term "alien" is not used in federal laws and statues. Instead, the term "foreign national" serves as its equivalent and is found in legal documents. The Immigration and Refugee Protection Act defines "foreign national" as "a person who is not a Canadian citizen or a permanent resident". Permanent residents and Canadian citizens are not considered as foreign.
The British Nationality Act 1772 regulated who was to be called a British subject.
U.S. law makes a clear distinction between aliens and immigrants by defining immigrants as a subset of aliens. Although U.S. law provides no overarching explicit definition of the term "illegal alien," the term is used in many statutes and elsewhere (e.g., court cases, executive orders). U.S. law also uses the term "unauthorized alien". U.S. immigration laws do use the phrase illegal immigrant, though the phrase has become a common and highly politicized term in the United States.
Because U.S. law says that a corporation is a person, the term alien is not limited to natural humans because what are colloquially called foreign corporations are technically called alien corporations. Because corporations are creations of local state law, a foreign corporation is an out-of-state corporation.
There are a multitude of unique and highly complex U.S. domestic tax laws and regulations affecting the U.S. tax residency of foreign nationals, both nonresident aliens and resident aliens, in addition to income tax and social security tax treaties and Totalization Agreements.
In Arab States of the Persian Gulf (UAE, Saudi Arabia, Kuwait, Oman, Bahrain and Qatar), many foreigners have lived in the country since birth or since independence. However these countries do not accord citizenship to many of them. As such, referring to these people as foreigners is seen by some as rude.
On Latvian passports, the mark nepilsoņi (alien) refers to non-citizens or former citizens of USSR who don't have voting rights for the parliament of Latvia but have rights and privileges under Latvian law and international bilateral treaties, such as the right to travel without visas to both the European Union and Russia, where latter is not possible for Latvian citizens.
