To get Peruvian citizenship as a foreign adult, you generally need five years of continuous legal residency in Peru, at least ten tax units (UIT) of lawful declared annual income, a clean criminal and immigration record, and a passing score on Spanish-language and Peruvian civics evaluations, then you apply through the Superintendencia Nacional de Migraciones. Those rules come from Law No. 32421, which replaced the older two-year framework and reshaped nearly every part of the process.
The Four Paths to Peruvian Nationality
Peru recognizes citizenship by birth on its soil, by descent from a Peruvian parent, by naturalization after a period of legal residency, and by marriage to a Peruvian citizen.
Anyone born in Peru is Peruvian from birth, regardless of the parents’ nationality. This jus soli rule is written directly into the Constitution.1Constitute. Peru 1993 (rev. 2021) Constitution No application is required.
Children born abroad to at least one Peruvian parent qualify by descent but must be registered at the Peruvian consulate nearest the child’s birthplace before turning 18. The Peruvian parent appears in person with their DNI, along with the child, the foreign birth certificate, passport-size photos, and copies of the parent’s identification. Registration is free.2Consulado del Perú. Births
One boundary matters here: naturalized Peruvians cannot pass citizenship to children born abroad through consular registration.2Consulado del Perú. Births That pathway is reserved for natural-born Peruvians. If you obtained citizenship through naturalization or marriage, children born outside Peru will not qualify this way.
Everything below concerns the naturalization and marriage pathways, which are the routes most foreign adults actually take.
What Law No. 32421 Changed
Peru significantly tightened its naturalization rules with Law No. 32421, replacing the framework under the older Law No. 26574. If you are reading older guides online, assume they are out of date.
The residency period doubled. General naturalization now requires five years of continuous legal residency in Peru, up from two. Marriage-based applicants need four years of marriage plus legal residency, also doubled.
The law added a minimum income threshold of ten Unidades Impositivas Tributarias (UIT) per year from lawful, declared activities in Peru. For 2026 the UIT is set at S/ 5,500, putting the minimum annual income at S/ 55,000, roughly US$15,000.3SUNAT. Indices y Tasas – Unidad Impositiva Tributaria That income has to be reported to SUNAT, Peru’s tax authority. Cash work and informal income will not satisfy this test.
A narrow exception exists for people who have made exceptional contributions to Peru, such as elite athletes or individuals recognized by the state for distinguished service. These applicants can qualify with only two years of residency, but the bar is high and cases are rare.
Retirees may have lost this route entirely. The previous law included a pathway for foreign retirees, but Law No. 32421 removed that provision. Unless the implementing regulations restore it, retirees without earned income in Peru may no longer qualify for naturalization.
Processing time grew as well. Migraciones now has up to 18 months to evaluate an application, with a possible six-month extension in complex cases. Plan for roughly two years from submission to decision.
The Naturalization Requirements in Detail
Residency and Income
You need five years of continuous legal residency immediately before applying, or four years of marriage plus residency if you are applying through a Peruvian spouse. Continuous means no significant gaps, and you must hold a valid Carné de Extranjería (foreign resident card) covering the whole period.
Your annual income must reach at least ten UIT and come from lawful activities properly declared to SUNAT.3SUNAT. Indices y Tasas – Unidad Impositiva Tributaria Employment income, business profits, and investment returns all count, but they need a paper trail. Bank statements alone will not do the job if the income was never reported to tax authorities.
Language and Civics
You will be evaluated in Spanish (or an officially recognized indigenous language) and tested on Peruvian history, geography, and civic life. Applicants who fail can be denied, so this is not a formality. Studying Peruvian civic education materials before the test is worth the effort.
Criminal Record
A clean criminal record is required both in Peru and internationally. Within Peru you will need clearance from local police authorities. Internationally, the process runs through Interpol’s office in Lima, which issues a Ficha de Canje Internacional certifying whether you have an active arrest warrant in any country. Appointments are booked online and you appear in person at the Monterrico office with your passport, a copy of your entry stamp, and payment receipt.4Ministerio del Interior – Plataforma del Estado Peruano. Obtener Ficha de Canje Internacional (Interpol) You will also need a criminal background check from your home country, typically through your embassy or national police.
No Serious Immigration Violations
Law No. 32421 added a separate hurdle: applicants must have no serious immigration sanctions on their Peruvian record. Overstaying a visa, working without authorization, or other migration violations can block your application even if you later held legal residency for years and have no criminal convictions.
Documents to Assemble
The documentation package is extensive and a single missing item can delay you by months. You will typically need:
- Your valid passport, plus copies of the data page and your most recent entry stamp.
- Your birth certificate from your country of origin, apostilled (or consular-legalized if your country is not a Hague Convention member) and officially translated into Spanish.
- Your marriage certificate, if applying through a Peruvian spouse, with the same apostille and translation requirements.
- Your Carné de Extranjería covering the full residency period.
- Criminal background checks: a home-country certificate and the Peruvian Ficha de Canje Internacional from Interpol.4Ministerio del Interior – Plataforma del Estado Peruano. Obtener Ficha de Canje Internacional (Interpol)
- Proof of income: SUNAT tax filings showing at least ten UIT in annual income from lawful, declared sources.
- Application forms from Migraciones (Superintendencia Nacional de Migraciones).
Every foreign document has to be apostilled and translated into Spanish by a certified translator. Certified translation typically runs $30 to $100 per page for standard certificates, with complex legal documents costing more. Apostille fees vary by country. Expect to process at least three or four foreign certificates.
How the Application Moves Through Migraciones
You file the package in person at a Migraciones office in Peru, with an appointment scheduled through their online system. Application fees are paid at submission. Applying from outside Peru is unusual, since the residency requirement means most applicants are already living there, but the nearest Peruvian consulate handles submissions when it happens.
After filing, you will be scheduled for the language evaluation and the civics test. Migraciones then reviews your documentation, criminal records, immigration history, and test results. The agency has up to 18 months to decide, with a possible six-month extension in exceptional cases. You are formally notified of the outcome.
If approved, you take an oath of allegiance to Peru in a formal ceremony. You then register with RENIEC, the national civil registry, to obtain your DNI. The DNI is the identity document every Peruvian citizen carries and serves as your proof of citizenship for voting, banking, property transactions, and everything else domestic.
Dual Citizenship
Peru does not require you to give up your existing nationality. The Constitution provides that Peruvian nationality can only be lost through express, voluntary renunciation before a competent Peruvian authority.1Constitute. Peru 1993 (rev. 2021) Constitution Acquiring another country’s citizenship later does not cost you your Peruvian one, and becoming Peruvian does not require you to renounce whatever passport you already hold.
Your home country may take a different view. Some countries require their citizens to renounce foreign nationalities or strip citizenship automatically on voluntary naturalization elsewhere. Check those rules before you take the Peruvian oath, because that is the point of no return.
What Citizenship Obligates You To Do
Vote
Voting in Peru is compulsory. The Constitution makes it mandatory for citizens between 18 and 70, and optional after 70.1Constitute. Peru 1993 (rev. 2021) Constitution Skip an election and you face a fine, and you may be blocked from completing certain government transactions until the penalty clears. This applies to naturalized citizens the same as anyone born in Peru, so time spent living abroad can create administrative problems when you come back.
File Taxes If You Live There
Peruvian tax residency is based on physical presence, not citizenship. Spend more than 183 days in Peru within any 12-month period and you are tax-domiciled, owing taxes on worldwide income. Spend fewer than 183 days and you are taxed only on Peruvian-source income. Becoming a citizen does not automatically trigger worldwide tax liability, but new citizens who have just finished five years of residency almost always meet the day-count test. You will file with SUNAT, and it is worth checking whether Peru has a tax treaty with your home country to avoid double taxation.
Register With the Armed Forces (Young Adults)
Peru requires young men and women to register with the armed forces at age 17. Active conscription is not routine, but the military retains authority to call a draft if volunteer numbers fall short. Whether this registration requirement applies to adults who naturalize later in life is not clearly spelled out, and it is worth asking Migraciones during your application.
Once you are Peruvian, the status is durable. The Constitution says nationality cannot be lost except by express renunciation before a competent Peruvian authority.1Constitute. Peru 1993 (rev. 2021) Constitution Moving abroad, acquiring another passport, or missing a vote does not strip it. Political rights such as voting or holding office can be suspended in circumstances the Constitution sets out, including certain criminal convictions, but the underlying nationality remains.
