Spanish Citizenship Requirements 2026: Full Guide

What Spanish nationality by residence is, and who it fits

Nationality by residence, nacionalidad por residencia, is the route foreigners use to become Spanish citizens after living legally in Spain for long enough to show real, continuous ties to the country. It is different from arraigo, which regularizes your immigration status, and different from citizenship by origin. This is the final step: turning years of legal residence into a Spanish passport, full voting rights, and, for most applicants, no more visa renewals or TIE cards ever again.

It fits three broad groups. First, long-settled foreigners of any nationality who have accumulated 10 years of continuous legal residence, typically former non-lucrative visa, work visa, or arraigo holders who simply kept renewing. Second, nationals of Ibero-American countries and a short list of historically linked countries, who reach the same result in a fifth of the time thanks to a reduced 2-year requirement. Third, spouses of Spanish citizens, who qualify after just 1 year of marriage and legal residence, provided the marriage is genuine, registered, and not separated.

It does not fit people who have not yet built the residence history the law requires, and it is not a shortcut around the underlying visa or arraigo process; those routes come first, nationality comes after. If you are still working out your residency status, our Arraigo Spain and Permanent Residency pages cover the steps that come before this one.

The three residence timelines: 10, 2, and 1 year

Spanish nationality law sets three different residence requirements depending on your background, and confusing them is a common, costly mistake. The standard rule is 10 years of continuous, legal residence in Spain, counted from your first legal residence permit, not from your arrival date if you were undocumented before regularizing. Two shorter routes exist for people with closer historical or family ties to Spain.

Nationals of Ibero-American countries, Andorra, the Philippines, Equatorial Guinea, and Portugal, along with Sephardic Jews who can document that ancestry, need only 2 years of legal residence. This is one of the broadest reduced-timeline categories in Spanish law and reflects centuries of shared history and language rather than any investment or income threshold. Spouses of Spanish citizens qualify after just 1 year of legal residence and marriage, as do a small number of other special cases: people born in Spain, people who were under the legal guardianship of a Spanish citizen or institution for two consecutive years, widowed spouses of Spanish citizens who were not separated at the time of death, and descendants of people who were originally Spanish.

Category	Residence required	Who qualifies
Standard	10 years	Most nationalities, no other special tie to Spain
Reduced (Ibero-American+)	2 years	Ibero-American countries, Andorra, Philippines, Equatorial Guinea, Portugal, Sephardic Jews
Spouses of Spanish citizens	1 year	Married to and legally residing with a Spanish citizen, not separated
Other special cases	1 year	Born in Spain, widowed spouses of Spaniards, former Spanish guardianship, descendants of Spaniards

All three routes still require the residence to be legal and, in most cases, continuous, meaning no long unexplained absences and no gaps where your permit lapsed. Short trips abroad are normal and expected; what causes problems is residence that was undocumented, interrupted, or based on a permit that was later found invalid. If you are pursuing the marriage route specifically, see our Spanish Citizenship by Marriage page for the details that route adds on top of the general process below.

The CCSE and DELE exams, and who is exempt

Two exams stand between almost every applicant and a completed nationality file. The CCSE, Conocimientos Constitucionales y Socioculturales de Espana, is a mandatory 25-question multiple-choice test on Spain’s constitution, institutions, geography, history, and culture, run by the Instituto Cervantes. There is a fixed official study bank of around 300 questions, the test draws from it, and a pass mark of 15 out of 25 is required. Nearly everyone applying for nationality by residence must sit and pass it, with narrow exemptions for young children and applicants with a certified disability that prevents them from taking it.

The DELE, Diploma de Espanol como Lengua Extranjera, proves your Spanish is good enough to integrate and participate in civic life, normally at A2 level or an accepted equivalent. This is where exemptions matter most: nationals of Spanish-speaking countries, most of Latin America plus Equatorial Guinea and, for historical reasons, the Philippines, do not need to sit it, and neither do applicants who can document that they were educated in Spanish. Everyone else, including most applicants from English-speaking, French-speaking, and other non-Spanish-speaking countries, needs to book and pass it as part of the file.

Both certificates go into your application file alongside your civil and residence documents. We help clients plan the study timeline for the CCSE, confirm whether the DELE exemption genuinely applies to their nationality, and book sessions early enough that results are in hand well before filing.

Full document checklist

Every case has small individual variations, but the core nationality by residence file looks like this:

• Birth certificate, apostilled and officially translated into Spanish, issued within the required validity window
• Passport and NIE, plus your full residence permit history showing continuous legal residence for the required period
• Criminal record certificate from Spain and from every country you have lived in as an adult, apostilled and translated where issued abroad
• Proof of continuous residence: padron (empadronamiento) history, Social Security contribution history, or equivalent employment records
• CCSE pass certificate, and a DELE A2 (or accepted equivalent) certificate unless you fall under an exemption
• For the marriage route: family record book (libro de familia) or marriage certificate, and proof of continuous cohabitation and legal residence with your Spanish spouse
• Completed official application form, filed through the Ministry of Justice’s online nationality portal
• Payment of the government processing fee (tasa)
• Where applicable, civil documents for any minor children included on the same application

Step-by-step process and realistic timeline

Stage 1: eligibility and document build

We start by confirming which of the three timelines applies to you and auditing your residence history for gaps. In parallel, we plan your CCSE study and confirm whether the DELE exemption applies, then assemble and sequence the apostilled and translated civil documents so nothing expires before filing. This stage typically runs 2 to 4 months, largely driven by exam scheduling and document turnaround rather than legal complexity.

Stage 2: filing and Ministry review

The completed file is submitted through the Ministry of Justice’s online nationality portal. Current 2026 processing times commonly run 12 to 24 months from filing to resolution, with most straightforward files landing closer to the middle of that range. The Ministry can request additional documents or clarification during this window, which we handle as it arises.

Stage 3: the oath and civil registry inscription

Once nationality is granted, you have a limited window, generally 180 days, to formally accept it by swearing or promising allegiance to the King and obedience to the Constitution and laws, then registering the grant at the Civil Registry. This final stage is covered in full in the next section, since it is also where clients most often save time by choosing the notary route over a civil registry appointment.

All in, a realistic total timeline from a clean starting file to a fully registered Spanish national is 14 to 28 months, with the Ministry review stage accounting for most of that time. Nothing about the final oath stage needs to add months of its own delay, provided you plan it correctly.

Jura de nacionalidad ante notario: the faster oath

Approval of your nationality is not the end of the process. Spanish law requires you to formally swear or promise allegiance to the King and obedience to the Spanish Constitution and laws, and to renounce your prior nationality where applicable, before the grant is finalized and registered. This act is called the jura, or in more neutral terms, la jura o promesa de fidelidad al Rey y obediencia a la Constitucion y a las leyes.

Traditionally this oath is taken at a Civil Registry (Registro Civil), and in many provinces, including large parts of Andalucia, registry appointment waiting lists for this specific step have run into many months, sometimes over a year, purely because of scheduling backlogs rather than anything about your file. Since a 2022 procedural reform, applicants can instead take the oath before a Spanish notary, the jura ante notario, and have the notary forward the signed act directly for registration.

Our 600 EUR base fee covers the full application through to approval. The optional 150 EUR jura ante notario add-on covers booking the notary appointment, preparing the act, attending with you, and forwarding the signed document for Civil Registry inscription, so the last mile of your nationality does not stall on registry availability.

Dual nationality rules, explained honestly

Spain restricts dual nationality as a general rule, but a wide set of bilateral treaties carves out an exception for most of the applicants who actually use this route. Nationals of Ibero-American countries, Andorra, the Philippines, Equatorial Guinea, and Portugal can become Spanish and keep their original nationality, because Spain has signed dual nationality treaties or has equivalent constitutional provisions with these countries. For the large share of our clients coming through the 2-year reduced timeline, this means the practical outcome is simple: two passports, no renunciation required in substance.

For nationals of countries outside that list, including the United Kingdom, the United States, most of the EU, and most of Asia and Africa, the official Spanish application form requires you to formally renounce your prior nationality as part of becoming Spanish. In practice, Spain does not notify your country of origin or actively police this renunciation, and plenty of clients from non-treaty countries end up holding both passports because their home country does not automatically strip nationality on the basis of a foreign declaration. Whether that is safe, advisable, or even legally consistent for you specifically depends entirely on your home country’s own nationality law, not on Spain’s.

We flag this issue for every non-Ibero-American client at the start of the process, not buried in the paperwork at the end, so you can make an informed decision with your eyes open rather than discover the consequence after the oath is already sworn.

Common refusal and delay reasons

Most nationality files that stall or get refused trace back to a small set of recurring issues:

• Gaps or inconsistencies in the residence history, including periods where a permit lapsed or was renewed late
• An expired, unapostilled, or improperly translated criminal record or civil certificate submitted with the file
• A missing, failed, or not-yet-issued CCSE or DELE result at the time of filing
• Unpaid or undeclared debts to Spanish public administrations, which the Ministry checks as part of good civic conduct
• Any pending criminal matter or unresolved legal issue that raises doubt about the “buena conducta civica” requirement
• Missing the 180-day window to complete the oath and registration after approval, which can put the grant itself at risk

Most of these are fixable before filing rather than after refusal, which is why the eligibility and document-build stage matters as much as the filing itself. Where a refusal does happen, the same appeal routes used across Spanish immigration law apply: a recurso de reposicion within one month, or a contencioso-administrativo court appeal within two months. See our Visa Denied? Appeal page for how that process works.

The Malaga angle

The nationality application itself is filed centrally through the Ministry of Justice’s online portal, not at a local office, so where you live in Spain does not change the substantive rules. Where Malaga comes in is everything around the file: your empadronamiento and Social Security history that proves continuous residence, your CCSE and DELE exam bookings, apostille and sworn translation coordination, and, once approved, the notary jura itself.

Our Malaga office keeps your residence and civil documentation organized from the day you start counting years, not just when you finally qualify to file, so the moment you cross the 10, 2, or 1-year line, the file is already close to ready. We book your CCSE and DELE sessions with enough lead time to hit your filing window, and once your nationality is granted, we book and attend your notary jura here rather than leaving you to navigate a civil registry queue alone.

If you are still working towards eligibility rather than ready to file today, our Permanent Residency and Residency Renewal pages cover keeping your permit history clean in the years before you qualify, and our Immigration Lawyer Malaga page covers the office and how we work day to day.
