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. Acquisition According to the Peruvian Constitution and nationality legislation passed in 1996 as well as an executive order declared in 1997, Peruvian nationality can be passed by birth via jus soli or by registration if born overseas and duly registered at a Peruvian embassy or consulate before the child reaches 18 years of age. As of March 2018, children born abroad to Peruvian parents are now able to register as Peruvian nationals even if they were not registered before age 18 (see next paragraph). In addition, infants or minor children found abandoned on Peruvian territory are assumed to be Peruvian nationals. This is consistent with the nationality law of most countries of the Americas. In 1992, Peru had a scheme of selling nationality to foreign investors for US$25,000. The scheme was closed the year after due to public outrage. Beginning in March 2018, those children born overseas to Peruvian mothers or fathers who were not registered before reaching 18 years of age can now also acquire Peruvian nationality by applying at their local consular office abroad, under an amendment to Article 52 of the Peruvian Constitution. Foreigners can also acquire Peruvian nationality, including: Minor children born overseas to foreign parents who, having lived in the territory of the republic since five years of age, can elect to acquire Peruvian nationality at 18 years of age by applying to the nearest Peruvian consulate or embassy in their own country Foreigners married to Peruvian spouses may acquire Peruvian nationality after two years of marriage and domicile in Peru.
