Chinese nationality law

Chinese nationality law details the conditions by which a person holds the nationality of the People's Republic of China (PRC). The primary law governing these requirements is the Nationality Law of the People's Republic of China, which came into force on September 10, 1980. Chinese nationality law is complex, as citizenship status and the rights attached to it vary across different jurisdictions within the PRC.

Chinese nationality law primarily follows the principle of jus sanguinis. A person born to at least one Chinese national parent generally acquires Chinese nationality at birth, regardless of place of birth. However, a child born abroad to Chinese parents who have settled overseas and acquired foreign nationality may not be recognized as a Chinese national.

The People's Republic of China nominally considers residents of the Taiwan to be Chinese citizens under its nationality law, based on its claim over territories administered by the Republic of China (ROC). However, following the Chinese Civil War and the retreat of the government of the Republic of China to Taiwan, residents of Taiwan are governed under a separate legal system in practice and do not exercise citizenship rights of the PRC. They may not vote, hold public office or receive social welfare benefits reserved for full citizens of mainland China.

Chinese nationals with mainland residency who voluntarily acquire foreign citizenship automatically lose Chinese nationality. By contrast, most residents of the special administrative regions of Hong Kong and Macau held foreign nationality under the laws of other states prior to them becoming part of the PRC in the 1990s. These individuals were permitted to retain such nationalities, which has resulted in a significant number of residents of Hong Kong and Macau holding foreign nationalities, most commonly British or Portuguese, alongside Chinese nationality.

Although mainland China, Hong Kong, and Macau are all administered by the PRC, Chinese citizens do not have automatic residence rights in all three jurisdictions; each territory maintains a separate residency and immigration policy. Voting rights and freedom of movement are tied to the region in which a Chinese citizen is domiciled, determined by hukou in mainland China and right of abode in the two special administrative regions.

Officially, the PRC permits foreign nationals to acquire Chinese citizenship through naturalization after renouncing their previous nationality. Foreigners may naturalize if they are permanent residents in any part of China or they have immediate family members who are Chinese citizens. However, naturalization is not treated as an individual right. In practice, naturalization is extremely rare and the process widely regarded as difficult due to the broad discretionary authority exercised by state authorities, and the absence of clearly defined eligibility criteria.
