Palauan nationality law is regulated by the 1980 Constitution of Palau, as amended; the 1994 Palau Citizenship Act, and its revisions; and international agreements entered into by the Palauan government. These laws determine who is, or is eligible to be, a national of Palau. The legal means to acquire nationality, formal legal membership in a nation, differ from the domestic relationship of rights and obligations between a national and the nation, known as citizenship. Palauan nationality is typically obtained either on the principle of jus soli, i.e. by birth in Palau or under the rules of jus sanguinis, i.e. by birth abroad to parents with Palauan nationality. It can be granted to persons with an affiliation to the country through naturalization.
