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.
Right of returnThe right of return is a principle in international law which guarantees everyone's right of voluntary return to, or re-entry to, their country of origin or of citizenship. The right of return is part of the broader human rights concept freedom of movement and is also related to the legal concept of nationality. While many states afford their citizens the right of abode, the right of return is not restricted to citizenship or nationality in the formal sense.
European Union citizenshipEuropean Union citizenship is afforded to all citizens of member states of the European Union (EU). It was formally created with the adoption of the 1992 Maastricht Treaty, at the same time as the creation of the EU. EU citizenship is additional to, as it does not replace, national citizenship. It affords EU citizens with rights, freedoms and legal protections available under EU law. EU citizens have freedom of movement, and the freedom of settlement and employment across the EU.
Portuguese peopleThe Portuguese people (Portugueses - masculine - or Portuguesas) are a Romance-speaking ethnic group and nation indigenous to Portugal, a country in the west of the Iberian Peninsula in the south-west of Europe, who share a common culture, ancestry and language. The Portuguese people's heritage largely derives from the proto-Celtic/proto-Italic Indo-European (Lusitanians, Conii) and Celtic peoples (Gallaecians, Turduli and Celtici), who were later Romanized after the conquest of the region by the ancient Romans.
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.
NaturalizationNaturalization (or naturalisation) is the legal act or process by which a non-citizen of a country may acquire citizenship or nationality of that country. It may be done automatically by a statute, i.e., without any effort on the part of the individual, or it may involve an application or a motion and approval by legal authorities. The rules of naturalization vary from country to country but typically include a promise to obey and uphold that country's laws and taking and subscribing to an oath of allegiance, and may specify other requirements such as a minimum legal residency and adequate knowledge of the national dominant language or culture.
Black peopleBlack is a racialized classification of people, usually a political and skin color-based category for specific populations with a mid to dark brown complexion. Not all people considered "black" have dark skin; in certain countries, often in socially based systems of racial classification in the Western world, the term "black" is used to describe persons who are perceived as dark-skinned compared to other populations.
