Peruvian nationality law is regulated by the 1993 Constitution of Peru, the Nationality Law 26574 of 1996, and the Supreme Decree 010-2002-IN, which regulates the implementation of Law 26574. These laws determine who is, or is eligible to be, a citizen of Peru. The legal means to acquire nationality, formal membership in a nation, differ from the relationship of rights and obligations between a national and the nation, known as citizenship. Peruvian nationality is typically obtained either on the principle of jus soli, i.e. by birth in Peru; or under the rules of jus sanguinis, i.e. by birth abroad to at least one parent with Peruvian nationality. It can also be granted to a permanent resident, who has lived in Peru for a given period of time, through naturalization.
