CNL meaning in Governmental ?

Chinese nationality law details the conditions in which a person holds People's Republic of China (PRC) nationality. Foreign nationals may naturalize if they are permanent residents in any part of China or they have immediate family members who are Chinese citizens. Residents of the Taiwan Area are also considered Chinese citizens, due to the PRC's extant claim over areas controlled by the Republic of China (ROC).

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 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. While Chinese law makes possessing multiple citizenships difficult, a large number of residents in Hong Kong and Macau have some form of British or Portuguese nationality due to the history of those regions as former European colonies.
