How to Obtain Spanish Citizenship

Spanish citizenship allows eligible individuals to become Spanish nationals and enjoy the rights and responsibilities associated with Spanish nationality. There are several legal pathways to obtain Spanish citizenship, depending on your nationality, family background, place of birth, and period of legal residence in Spain.

The main routes include citizenship by residency (naturalization), citizenship by descent, citizenship through the special option procedure, and citizenship through marriage-related eligibility. Each pathway has specific requirements, documentation, and application procedures that must be satisfied before citizenship can be granted.

Spanish Citizenship by Residency (Naturalization)

Citizenship by residency is one of the main ways foreign nationals can become Spanish citizens. Applicants must generally have lived legally and continuously in Spain for the required period immediately before submitting their application, while meeting the applicable requirements for good civic conduct and integration into Spanish society.

The required period of legal residence depends on your circumstances and nationality. The principal residency periods include:

• 10 years: The general residency requirement for most foreign nationals.
• 5 years: For individuals who have been officially recognized as refugees.
• 2 years: For nationals of Ibero-American countries, Andorra, the Philippines, Equatorial Guinea, and Portugal, as well as eligible individuals of Sephardic origin, subject to the applicable legal requirements.
• 1 year: For certain qualifying applicants, including those born in Spain, individuals married to Spanish citizens who meet the legal residence and marriage conditions, widowed spouses of Spanish citizens, and people born outside Spain to a Spanish parent or grandparent in circumstances covered by the law.

It is important to distinguish legal residence from other forms of stay in Spain. Time spent in Spain on a student authorization generally does not count toward the residence period required for citizenship by residency. Applicants should verify their immigration status and qualifying residence dates before applying.

Spanish Citizenship by Descent (Citizenship by Origin)

Spanish citizenship by descent may be available to individuals who have a Spanish parent or who qualify under specific provisions of Spanish nationality law. Depending on the circumstances, nationality may be acquired from birth or through a declaration of option.

• Children of Spanish parents: Individuals born to at least one Spanish parent are generally Spanish citizens by origin, subject to the applicable legal rules.
• Citizenship by option: Certain individuals, including eligible minors whose parents acquire Spanish nationality after their birth, may have the right to opt for Spanish citizenship.
• Children of Spanish citizens: Other individuals with a qualifying legal relationship to a Spanish citizen may be eligible under the nationality-by-option provisions.

Applicants should consult the Spanish Civil Registry or the relevant Spanish consulate to determine whether they qualify by origin or option and which birth certificates, parentage records, and other supporting documents are required.

Citizenship Through Marriage to a Spanish Citizen

Marriage to a Spanish citizen does not automatically grant Spanish nationality. However, a foreign spouse may qualify for the reduced one-year legal residence requirement for citizenship by residency if the applicable conditions are met.

Generally, the applicant must have been legally resident in Spain for at least one year immediately before applying, be married to a Spanish citizen for at least one year, and not be legally or de facto separated. The applicant must also satisfy the other requirements applicable to naturalization.

Before applying, confirm that your marriage and residence history meet the current legal requirements and prepare the relevant marriage certificate, residence documentation, and identity records.

Spanish Citizenship by Option and Special Legal Provisions

Spanish nationality law provides a citizenship-by-option procedure for people who meet specific family or legal criteria. Eligibility depends on the applicant's relationship to a Spanish citizen, parental nationality circumstances, age, and other conditions established by law.

The Law of Democratic Memory (Law 20/2022) introduced a special pathway for certain descendants of Spaniards affected by historical exile and related circumstances. The application period under this law expired in October 2025. Applicants who believe they qualify through another nationality provision should consult the relevant Civil Registry or Spanish consulate for guidance on currently available routes.

General Requirements for Spanish Citizenship

Applicants seeking Spanish citizenship through residency must generally provide supporting documentation and demonstrate that they meet the legal conditions for nationality. Depending on the applicant's circumstances, the requirements may include the following:

• Spanish language test: Pass the DELE A2 Spanish language examination or a higher level, unless exempt under the applicable rules.
• Constitutional and cultural knowledge test: Pass the CCSE examination, which assesses knowledge of Spanish constitutional and sociocultural matters, unless an exemption applies.
• Good civic conduct: Provide the required criminal record documentation and satisfy the legal good-conduct requirement. Foreign criminal record certificates may need legalization or an apostille and an official translation, depending on the issuing country and applicable rules.
• Proof of legal residence: Demonstrate that you have completed the qualifying period of legal and continuous residence in Spain.
• Oath or promise of allegiance: After approval, complete the required declaration of allegiance to the King and obedience to the Constitution and laws of Spain within the applicable deadline.
• Previous nationality: Depending on your nationality and legal circumstances, you may be required to declare renunciation of your previous nationality. Exceptions apply to certain nationalities and categories established by Spanish law.

Exemptions from language or cultural examinations may apply to certain applicants. The documentation required for criminal records and nationality renunciation also varies according to individual circumstances, so applicants should check the official requirements before submitting their applications.

How to Apply for Spanish Citizenship

The application process depends on the legal pathway through which you qualify. Citizenship by residency is generally requested through the official electronic services of the Spanish Ministry of Justice, while nationality by origin or option may involve registration or a declaration before the competent Civil Registry or Spanish consulate.

Before starting your application, identify the appropriate pathway, check the required residence period or family eligibility conditions, obtain the necessary civil status and identity documents, and determine whether language examinations or additional certificates are required.

Once your application has been approved, complete any required oath or promise, registration, and nationality formalities within the applicable deadlines. Approval of an application does not necessarily mean that every remaining registration step has been completed.

Important Information Before Applying for Spanish Nationality

Spanish citizenship requirements can differ according to nationality, family history, immigration status, and the legal basis of the application. Residency periods and document requirements should therefore be assessed individually.

For accurate and up-to-date information, consult the official Spanish Ministry of Justice, the relevant Civil Registry, or a Spanish consulate. These authorities can confirm your eligibility, the documents required, current application procedures, and any exemptions that may apply to your case.
