Mexican citizens can become Spanish citizens after just two years of legal residency in Spain, compared with the ten years required of most other foreigners, and they do not have to give up their Mexican nationality to do it. Spanish citizenship for Mexican citizens also comes with an unusual break on the language test: because Spanish is your native language, the DELE A2 exam is waived. You still need legal residency to start the clock, the right documents, and a passing score on Spain’s civics exam.
The Two-Year Residency Route
The most common path is naturalization by residency. Nationals of Latin American countries, including Mexico, qualify for a reduced residency requirement of two years instead of ten.1Gobierno de España. Acquiring Nationality – Residence – Citizens The same shortcut applies to nationals of Andorra, the Philippines, Equatorial Guinea, Portugal, and people of Sephardic origin.
The two-year clock starts when you obtain legal residency in Spain, not when you first entered the country. The residency has to be continuous and legal, which means holding a valid residence permit for the full period. Extended trips outside Spain during those two years can interrupt the count, so plan travel carefully.
The expedited timeline is for Mexicans by origin, meaning people born in Mexico or who acquired Mexican nationality through parentage. Someone who naturalized as Mexican after being born in a non-Ibero-American country may not qualify for the shortened residency.
Faster and Alternative Routes
Marriage to a Spanish Citizen
If you are married to a Spanish citizen, the residency requirement drops to one year. You must be legally residing in Spain, living with your spouse, and not legally or de facto separated at the time you apply.1Gobierno de España. Acquiring Nationality – Residence – Citizens
Descent or Option
Spanish law lets certain people with family ties to Spain claim citizenship by “option.” You may qualify if you were born to a Spanish parent, were adopted by a Spanish citizen before turning eighteen, or were under the legal guardianship of a Spanish citizen. People born outside Spain to a parent or grandparent who was originally Spanish can apply after just one year of legal residency.1Gobierno de España. Acquiring Nationality – Residence – Citizens For many Mexican families with Spanish grandparents, this route can matter more than the two-year residency track.
Democratic Memory Law: Window Closed
Spain’s 2022 Democratic Memory Law, often called the “Grandchildren Law,” opened a special path for descendants of Spaniards who emigrated or were exiled during the Civil War and Franco era. Many Mexican families qualified through relatives who fled to Mexico in the late 1930s. The application window closed on October 21, 2025. Files submitted before the deadline will still be processed, but no new applications are accepted.
Getting the Residency That Starts the Clock
Mexican citizens don’t have visa-free long-term residency rights in Spain, so before the two-year count can begin you need a visa that leads to a residence card.
Non-Lucrative Residence Visa
Designed for people who can support themselves without working in Spain. You must show funds equal to at least 400% of Spain’s public income indicator (IPREM) for the first year, plus 100% more for each family member.2Ministry of Foreign Affairs, European Union and Cooperation. Non-Working (Non-Lucrative) Residence Visa The 2026 monthly IPREM is €600, so a single applicant needs roughly €28,800 in provable funds for the year. You also need private health insurance covering all risks with no deductibles, copayments, or coverage limits. This visa does not permit work in Spain, so it fits retirees or people living off savings and investments.
Digital Nomad (Telework) Visa
For people working remotely for a company outside Spain. You must have at least three months of employment with the foreign company before applying, and the relationship must be expected to continue for at least another year.3Ministry of Foreign Affairs, European Union and Cooperation. Telework (Digital Nomad) Visa Income requirements are tied to Spain’s minimum salary: about €2,368 per month for a single applicant, more for accompanying family.
Work Visa
A traditional employment visa requires a job offer from a Spanish employer. The employer first obtains a work authorization, and then you apply for the residence and work visa at a Spanish consulate. It is more complex, but the residency it produces fully counts toward the two-year citizenship requirement.
Family Reunification Visa
If your spouse, parent, or child is a Spanish citizen or legal resident, you may qualify for residency through family reunification. A spouse of a Spanish citizen applies for a family member residence visa and must show the relationship, adequate financial means, and suitable housing in Spain.4Ministry of Foreign Affairs, European Union and Cooperation.

Documents You Will Need
Spanish authorities are exacting about paperwork, and every foreign document needs both an apostille and a sworn translation into Spanish. Apostilles for Mexican documents are issued by the Secretaría de Relaciones Exteriores. Apostille processing and sworn translations can each take weeks, so start early.
The core file usually includes:
- Birth certificate, apostilled and translated by a sworn translator.
- Valid Mexican passport with a photocopy of the biometric data page. Passports issued more than ten years ago are typically not accepted.4Ministry of Foreign Affairs, European Union and Cooperation. Residence Visas Family Members of Spanish Citizen
- Foreigner Identification Number (NIE), issued when you first register as a foreign resident.
- Proof of legal residency: your residence card and a Certificado de Empadronamiento confirming your registered Spanish address.
- Criminal record certificates from both Mexico and Spain. The Mexican certificate (Constancia de Antecedentes Penales) must be apostilled and translated; the Spanish one is requested from the Ministry of Justice. Both must be dated within six months of your application. If you lived in another country for six months or more during the past five years, you also need criminal records from there.5Ministry of Foreign Affairs, European Union and Cooperation.

- Marriage certificate if applicable, apostilled and translated.
The CCSE Exam (and Why You Skip the DELE)
Every citizenship applicant must pass the CCSE, which tests knowledge of Spain’s constitution, government, and culture. It has 25 multiple-choice questions; you need at least 15 correct. Registration costs €85, and passing results are valid for four years, so you can take it before your two-year residency is complete. The Instituto Cervantes runs the test at centers in Spain and abroad.
Spain normally also requires the DELE A2 language proficiency exam, but Mexican citizens are exempt because Spanish is their native language. That exemption covers nationals of every Spanish-speaking country.
Do not underestimate the CCSE. Questions cover autonomous communities, the structure of parliament, and cultural and historical details that are not obvious even for fluent Spanish speakers. Study materials are available from the Instituto Cervantes, and a few weeks of preparation is standard.
Filing the Application
With your documents and CCSE results ready, you submit the citizenship application through the Ministry of Justice’s online platform, SEDE electrónica.6Ministry of Justice. Spanish Nationality by Residence You will need a digital certificate or Cl@ve PIN to log in. In limited cases the application can be filed in person at a Civil Registry office.
The application requires paying a government fee (tasa) of approximately €104 using the Modelo 790, Código 026 payment form. It is non-refundable regardless of outcome. Keep the payment receipt.
After submission you get a confirmation with a file number for tracking. Online applications tend to move faster; some resolve in five to six months. Paper filings or files that need extra documentation can run one to two years. If the Ministry asks for supplementary documents, respond quickly.
The Oath, the DNI, and the Passport
Approval isn’t the last step. You have to swear or affirm allegiance to the King of Spain and obedience to the Constitution and laws.1Gobierno de España. Acquiring Nationality – Residence – Citizens The ceremony takes place at the local Civil Registry, or in some cases before a notary. The clerk verifies your approval notice and asks formal questions confirming acceptance of Spain’s legal system.
Then the Civil Registry registers your birth as a Spanish national. Some offices do this the same day as the oath in about twenty minutes; others send the file to a different clerk and take several more weeks. Once registration is done, you can book an appointment at a national police station for your DNI and apply for a Spanish passport.
You typically have 180 days from the approval notification to complete the oath. Miss it and your approval can be revoked, so schedule the appointment as soon as you’re notified.
If Your Application Is Denied
A denial can be appealed. The first step is an administrative appeal called a recurso de reposición, filed with the same body that issued the denial. The deadline is one month from the date you receive the decision, and the government has one month to answer.7Ministry of Territorial Politics and Democratic Memory. Optional Appeal for Reconsideration Silence within that month counts as a tacit rejection.
If the administrative appeal fails, you can escalate to the courts through a contentious-administrative appeal within two months. Legal representation becomes essential at that stage. Most denials come from incomplete documentation or gaps in residency rather than fundamental ineligibility, so it’s worth consulting an immigration lawyer before the first appeal deadline runs.
Keeping Your Mexican Passport
Mexican applicants get an unusually good arrangement from both governments. Spain does not require nationals of Latin American countries to renounce their original nationality when acquiring Spanish citizenship.1Gobierno de España. Acquiring Nationality – Residence – Citizens Most other nationals must formally renounce their previous citizenship during the oath ceremony. Mexicans skip that.
Mexico is equally accommodating. Since a 1998 constitutional amendment, no Mexican citizen by birth can be stripped of Mexican nationality, even after voluntarily acquiring citizenship in another country.8Library of Congress. Mexico: Law on Dual Nationality The protection applies specifically to Mexicans by birth. If you became Mexican through naturalization, taking Spanish citizenship could cost you your Mexican nationality under Mexican law.
In practice, dual nationality means you can live and work freely in both countries and, with the Spanish passport, throughout the European Union. You can hold property and bank accounts in both. You can pass both nationalities to your children. The main restriction is that certain Mexican government positions are reserved for citizens who hold no other nationality.
Tax Consequences
Becoming a Spanish resident (which you already are before naturalizing) makes you a Spanish tax resident, and Spain taxes worldwide income. If you keep income sources, investments, or property in Mexico, you have to report that income to Spanish tax authorities.
Spain also imposes a wealth tax on residents whose total assets exceed €2 million, plus an additional solidarity tax on net assets above €3 million. Rates and exemptions vary by autonomous community, so where you live in Spain affects your bill. A Mexico-Spain bilateral tax treaty can prevent double taxation on the same income, but using it correctly takes planning. Speak with a tax advisor familiar with both systems before you finalize a move, especially if you plan to keep business interests or rental properties in Mexico.
