The special administrative regions (SAR) of the People's Republic of China are one of four types of province-level divisions of the People's Republic of China directly under the control of its Central People's Government, being integral areas of the country. As a region, they possess the highest degree of autonomy from China's central government. However, despite the relative autonomy that the Central People's Government offers the special administrative regions, the National People's Congress and its Standing Committee remains capable of enforcing laws for the special administrative regions.
Jus soli, meaning 'right of soil', is the right of anyone born in the territory of a state to nationality or citizenship. Also commonly referred to as birthright citizenship in some Anglophone countries, it is a rule defining a person's nationality based on their birth in the territory of the country. 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.

In 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. At the end of 2022, the United Nations High Commissioner for Refugees estimated 4.4 million people worldwide as either stateless or of undetermined nationality, 90,800 (+2%) more than at the end of 2021.

A certificate of identity, sometimes called an alien's passport, is a travel document issued by a country to non-citizens residing within their borders who are stateless persons or otherwise unable to obtain a passport from their state of nationality. Some states also issue certificates of identity to their own citizens as a form of emergency passport or otherwise in lieu of a passport. The visa requirements of certificates of identity may be different from those of regular passports.
The Convention Relating to the Status of Refugees, also known as the 1951 Refugee Convention or the Geneva Convention of 28 July 1951 is a United Nations multilateral treaty that defines who a refugee is and sets out the rights of individuals who are granted asylum and the responsibilities of nations that grant asylum. The convention also sets out which people do not qualify as refugees, such as war criminals. The convention also provides for some visa-free travel for holders of refugee travel documents issued under the convention.
Nationality 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. In law, nationality describes the relationship of a national to the state under international law and citizenship describes the relationship of a citizen within the state under domestic statutes. Different regulatory agencies monitor legal compliance for nationality and citizenship. A person in a country of which he or she is not a national is generally regarded by that country as a foreigner or alien. A person who has no recognised nationality to any jurisdiction is regarded as stateless.

The Convention on the Reduction of Statelessness is a 1961 United Nations multilateral treaty whereby sovereign states agree to reduce the incidence of statelessness. The Convention was originally intended as a Protocol to the Convention Relating to the Status of Refugees, while the 1954 Convention Relating to the Status of Stateless Persons was adopted to cover stateless persons who are not refugees and therefore not within the scope of the Convention Relating to the Status of Refugees.

Somaliland a self-declared independent country in the Horn of Africa in which inhabitants were initially governed by various kinship networks. Upon contact with Europeans, treaties were signed in the area to secure rights to trade in the territory in exchange for protection of clans from rivals. Britain formally extended a protectorate over British Somaliland in 1898. Inhabitants of Somaliland were British Protected Persons from that date until they gained their independence in 1960 and joined in the union of their state with Italian Somaliland to form the Somali Republic. Inhabitants derive their nationality from Somali law. The legal means to acquire nationality, formal legal membership in a sovereign nation, differ from the domestic relationship of rights and obligations between a citizen within its nation, known as citizenship. Nationality describes the relationship of an individual to the nation under international law, whereas citizenship is the domestic relationship of an individual within the state. As the African Union, United Nations, and no independent nation has recognized its national sovereignty, Somaliland's inhabitants are Somali nationals, but since declaring its independence in 1991, it has de facto authority to control internal affairs and citizenship within its territory.
