Spanish Citizenship by Residence

The most complete legal status in Spain

Spanish citizenship is the highest and most complete status available to foreign residents in Spain. Once granted, it provides full civil and political rights, access to the Spanish passport and the freedom to live, work and establish yourself in any EU Member State.

Unlike temporary or long-term residence permits, Spanish nationality does not expire, does not require renewals and only ends in the limited circumstances set out in law. It is a long-term decision that consolidates your legal and personal ties to Spain.

At NomadTaxSpain, we guide individuals, families and long-term residents through the entire nationality by residence process, from early eligibility checks to the final oath at the Civil Registry.

What is Spanish nationality by residence?

Nationality by residence is the general route through which foreigners who have lived in Spain legally, continuously and effectively for a set period can obtain Spanish citizenship.

It is regulated mainly by:

• Articles 21–23 of the Spanish Civil Code.
• The Civil Registry Law and its regulations.
• Law 19/2015 on administrative reform and digital filing.
• Royal Decree 1004/2015, which governs the residence-based nationality procedure.

Applications are processed centrally by the Directorate-General for Legal Security and Public Trust within the Ministry of Justice. Filing is now primarily electronic via the Ministry's online platform, which significantly streamlines the initial stages compared with older paper-based procedures.

Who can apply? Minimum residence periods

To obtain Spanish nationality by residence, you must have lived in Spain legally, continuously and immediately prior to your application for a minimum period determined by law:

• 10 years — General rule for most applicants.
• 5 years — Recognised refugees.
• 2 years — Nationals of Latin American countries, Andorra, the Philippines, Equatorial Guinea, Portugal, or individuals of Sephardic origin.
• 1 year — Special cases, such as:
  • Born in Spain to foreign parents.
  • Married to a Spanish citizen for more than one year, with proven cohabitation.
  • Widow or widower of a Spanish national, if not legally separated at the time of death.
  • Child or grandchild of a Spanish national in specific circumstances.

A precise calculation of residence periods, absences and type of residence permits is essential before filing, especially for applicants using reduced residence periods.

Key legal requirements

• Legal, continuous and effective residence

  You must hold valid residence permits (or EU certificates) during the entire qualifying period. Continuity is typically proven through:

  • Historic empadronamiento (census registration).
  • Immigration and residence records.
  • Social Security or tax records where relevant.
• Good civic conduct

  Evaluated mainly through criminal records in Spain and abroad, as well as the absence of significant unpaid debts with the Tax Agency or Social Security.

• Sufficient integration into Spanish society

  For most adult applicants, integration is assessed via official exams:

  • CCSE exam: constitutional and sociocultural knowledge of Spain.
  • DELE A2 exam: Spanish language exam for non-Spanish-speaking applicants.

  Exemptions or adaptations may apply for minors, people with disabilities, or nationals of Spanish-speaking countries (who may be exempt from the DELE A2).

• Final oath at the Civil Registry

  After approval, you must take a formal oath of loyalty to the King and the Spanish Constitution at the Civil Registry. In some cases, you must also formally renounce your previous nationality.

  Spain does not require renunciation for nationals of Latin American countries, Andorra, the Philippines, Equatorial Guinea, Portugal or Sephardic Jews.

  For U.S. citizens, Spain requires a formal renunciation before the Civil Registry, but under U.S. law only a renunciation made before U.S. authorities has legal effect, so the Spanish renunciation does not usually result in loss of U.S. citizenship.

Required documentation

All documents must be valid, consistent and, where necessary, legalised or apostilled and accompanied by a sworn translation into Spanish.

• Official online application form via the Ministry of Justice platform.
• Payment receipt for fee Modelo 790 – Código 026.
• Copy of TIE (residence card) or EU registration certificate.
• Complete passport (all pages).
• Updated empadronamiento certificate.
• Birth certificate from your country of origin, properly legalised/apostilled and sworn translated where required.
• Criminal record certificates from your country of origin and any country where you have lived since age 18.
• Spanish criminal record certificate (often obtained automatically by the Ministry with your consent).
• CCSE and DELE certificates, where applicable (valid for four years for nationality purposes).
• Specific documents for reduced residence periods: marriage certificates, proof of cohabitation, birth certificates of Spanish parents or grandparents, refugee recognition decisions, etc.

The Spanish nationality application process

1. Preparation and collection of documents

   This includes obtaining apostilles, sworn translations and updated criminal certificates, as well as organising evidence of your residence history. It is also advisable to resolve outstanding issues with the Tax Agency or Social Security, and to cancel or update criminal records where the law allows.

2. CCSE and DELE exams

   Most adult applicants must pass the CCSE exam (knowledge of the Spanish Constitution and culture) and, for non-Spanish speakers, the DELE A2 Spanish language exam. Both certificates are valid for four years for nationality applications.

3. Electronic submission of the application

   The application is filed via the Ministry of Justice's online platform using a digital certificate or Cl@ve credentials. In exceptional cases, paper filing at the Civil Registry may be possible.

4. Administrative review and reports

   The Ministry of Justice requests reports from:

   • Police and security services (including CNI).
   • Tax Agency.
   • Social Security.
   • Other authorities where necessary.

   In some cases, applicants may be called for an interview or even a home visit to confirm residence and integration.

5. Requests for additional documents

   If there are gaps, inconsistencies or missing documents, the Ministry will issue a request for corrections or additional information within a set deadline. Failure to reply on time can lead to the application being closed without a decision.

Resolution and processing times

By law, the Ministry of Justice has one year from the filing of a complete application to issue a decision. In practice, high volumes of applications often lead to longer processing times.

If one year passes without an express decision, administrative silence is considered negative. At that point, you may file a judicial appeal before the National Court. Many applicants choose between waiting for an express resolution or litigating, depending on the status of Ministry processing campaigns and the strength of their file.

After approval: oath, registration and identity documents

Once your nationality is granted, the process continues with important formalities:

• You must attend the Civil Registry to take the oath or promise of loyalty to the King and the Constitution, and to renounce your previous nationality where required.
• Your Spanish birth registration is created in the Civil Registry, which legally consolidates your status as a Spanish citizen.
• You can then apply for your Spanish DNI and passport, which provide proof of nationality and enable free movement within the EU.

Practical observations and tips

• Plan ahead: apostilles, sworn translations and updated criminal certificates often take time and may have limited validity (typically 3–6 months).
• Check document validity: many certificates must be recent at the time of filing. Submitting expired documents is a common cause of delays and requests for corrections.
• Monitor absences: long or frequent absences from Spain can undermine the requirement of continuous residence, especially when close to the minimum residence threshold.
• Understand renunciation: for dual nationals, especially U.S. citizens or Latin Americans, it is important to understand the practical effects and the difference between Spanish and foreign rules on loss of nationality.
• Track your file: applications can be monitored through the Ministry's online tracking portal, often referred to as "Cómo va lo mío".
• Appeal options: negative decisions and implicit denials by silence may be challenged via administrative reconsideration or judicial proceedings.
