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.
Jus soliJus soli (dʒʌs_ˈsoʊlaɪ , juːs_ˈsoʊli ), commonly referred to as birthright citizenship, is the right to acquire nationality or citizenship by being born within the territory of a state. Jus soli was part of the English common law, in contrast to jus sanguinis, which derives from the Roman law that influenced the civil-law systems of mainland Europe.
NationalityNationality is the status of belonging to a particular nation, defined as a group of people organized in one country, under one legal jurisdiction, or as a group of people who are united by a common culture, history, traditions, and awareness of a common origin. In the international law, nationality is a legal identification establishing the person as a subject, a national, of a sovereign state. It affords the state jurisdiction over the person and affords the person the protection of the state against other states.
Nationality lawNationality law is the law of a sovereign state, and of each of its jurisdictions, that defines the legal manner in which a national identity is acquired and how it may be lost. In international law, the legal means to acquire nationality and formal membership in a nation are separated from the relationship between a national and the nation, known as citizenship. Some nations domestically use the terms interchangeably, though by the 20th century, nationality had commonly come to mean the status of belonging to a particular nation with no regard to the type of governance which established a relationship between the nation and its people.
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.
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.

German nationality lawGerman nationality law details the conditions by which an individual is a national of Germany. The primary law governing these requirements is the Nationality Act, which came into force on 1 January 1914. Germany is a member state of the European Union (EU) and all German nationals are EU citizens. They have automatic and permanent permission to live and work in any EU or European Free Trade Association (EFTA) country and may vote in elections to the European Parliament.

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.
British nationality lawThe primary law governing nationality in the United Kingdom is the British Nationality Act 1981, which came into force on 1 January 1983. Regulations apply to the British Islands, which include the UK itself and the Crown dependencies, and the 14 British Overseas Territories.

The principal class of British nationality is British citizenship, which is associated with the British Islands.
