Multiple citizenshipMultiple/dual citizenship (or multiple/dual nationality) is a person's legal status in which the person is at the one time recognized by more than one country under its nationality and citizenship law as a national or citizen of that country. There is no international convention which determines the nationality or citizenship status of a person, which is consequently determined exclusively under national laws, that often conflict with each other, thus allowing for multiple citizenship situations to arise.
CitizenshipCitizenship is an allegiance of a person to a state. Each state determines the conditions under which it will recognize persons as its citizens, and the conditions under which that status will be withdrawn. Recognition by a state as a citizen generally carries with it recognition of civil, political, and social rights which are not afforded to non-citizens. In general, the basic rights normally regarded as arising from citizenship are the right to a passport, the right to leave and return to the country or countries of citizenship, the right to live in that country, and to work there.
StatelessnessIn international law, a stateless person is someone who is "not considered as a national by any state under the operation of its law". Some stateless people are also refugees. However, not all refugees are stateless, and many people who are stateless have never crossed an international border. On November 12, 2018, the United Nations High Commissioner for Refugees stated there are about 12 million stateless people in the world. The status of a person who might be stateless ultimately depends on the viewpoint of the state with respect to the individual or a group of people.
Illegal immigrationIllegal immigration is the migration of people into a country in violation of the immigration laws of that country or the continuous residence without the legal right to live in that country. 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. Asylum seekers who are denied asylum may face impediment to expulsion if the home country refuses to receive the person or if new asylum evidence emerges after the decision.
