Naturalization through long-term residence is one of the most common legal routes to obtaining Spanish citizenship. In Spain, foreign nationals who have lived legally and continuously in the country for a number of years may qualify to apply for citizenship through this path. This method is especially relevant for individuals who do not have Spanish ancestry, but who have built their lives in Spain and wish to secure full rights and legal recognition as Spanish citizens. Marfour International Law Firm specializes in assisting clients throughout the entire naturalization process, offering expert legal support and guidance.

Naturalization Through Long-Term Residence in Spain

Spain offers the opportunity to apply for citizenship through naturalization after meeting certain residency conditions. This route is available to many foreign nationals who have lived in Spain legally over time.

Legal Basis and Residency Requirement

The standard rule under Spanish law is that a person must reside legally and continuously in Spain for 10 years to be eligible for citizenship by naturalization. This period must be uninterrupted, and the applicant must demonstrate integration into Spanish society, including knowledge of the Spanish language and culture.

However, there are exceptions:

  • Citizens of Latin American countries, Andorra, the Philippines, Equatorial Guinea, Portugal, and people of Sephardic origin may apply after only 2 years of legal residence.
  • Refugees may apply after 5 years.
  • People married to Spanish citizens or born in Spain may have shorter requirements as well.

Marfour International Law Firm can help you assess whether you qualify for a reduced residency period and prepare the proper documentation for your application.

Continuous Legal Residence

The term “long-term residence” specifically refers to legal residence—meaning you must have a valid residence permit. Interruptions in your stay or unregistered absences can lead to delays or denial. Marfour’s legal team ensures your documentation, timelines, and legal permits remain compliant throughout your residency.

Documentation and Application Process

Applying for Spanish citizenship through naturalization requires careful documentation, legal knowledge, and strict adherence to procedures.

Documentation and Application Process

Essential Documents for Application

Applicants must prepare and submit several documents, including:

  • Valid passport and residence card
  • Birth certificate (legalized and translated)
  • Criminal background checks from both Spain and your country of origin
  • Proof of legal residence in Spain 
  • DELE A2 Spanish language certificate
  • CCSE test results on Spanish society and constitution

Marfour International Law Firm helps clients collect and translate all necessary documents, ensuring they meet legal formatting and authentication requirements.

Application Submission and Processing

Citizenship applications are submitted through Spain’s electronic system or in-person at Civil Registries. Once submitted, the processing time may range from 1 to 3 years, depending on the administrative backlog.

Marfour’s legal experts monitor your application status, follow up with Spanish authorities, and respond to any government requests or legal objections during the waiting period.

Language and Integration Requirements

Spanish authorities require proof that applicants are integrated into Spanish society. Language and cultural knowledge are essential parts of this process.

DELE A2 Language Certificate

Applicants must demonstrate their Spanish language ability by passing the DELE A2 exam, which evaluates reading, writing, listening, and speaking at a basic-intermediate level. This requirement is waived for nationals of Spanish-speaking countries.

CCSE Test

All applicants must also pass the CCSE test, which assesses knowledge of Spanish history, constitution, and daily civic life. Marfour International Law Firm helps clients prepare for this test and schedule their examination dates in advance.

Special Considerations and Exceptions

Naturalization by long-term residence is flexible in some cases, but rigid in others. Here are some key exceptions and situations where legal guidance becomes essential.

Reduced Residency for Certain Nationals

As noted earlier, nationals from Latin American countries, Portugal, and others may qualify after just two years of residence. Similarly, people married to Spanish citizens or those born in Spain can apply under shortened timelines.

Children and Dependents

Children born in Spain to foreign parents may acquire Spanish nationality more easily. If your child has resided in Spain for at least one year, they may apply for citizenship as a minor with the assistance of a legal representative.

Criminal Records and Rejections

A criminal record—either in Spain or your home country—can be a major obstacle to naturalization. Marfour International Law Firm works with clients to evaluate risks, request expungements if applicable, and build strong legal cases even in complex situations.

FAQs 

Can I apply for citizenship if I’ve lived in Spain for 9 years and 11 months?

No. The 10-year requirement must be complete at the time of application, unless you’re eligible for a reduced residency path. You may apply only after meeting the full timeline.

Does time spent as a student count toward long-term residence?

No. Student residency is considered temporary and does not count toward the years required for naturalization.

Can I leave Spain during my 10-year residency period?

Yes, but only for short and documented absences. Extended or unregistered stays outside Spain may break the continuity of residence and delay your eligibility.

Is dual citizenship allowed?

Spain allows dual citizenship with certain countries, such as those in Latin America, the Philippines, and Portugal. Others may need to renounce their previous nationality. Marfour can advise on dual citizenship based on your country of origin.

How long does it take to receive Spanish citizenship after applying?

Processing can take between 1 to 3 years. Having legal representation from Marfour can help speed up the process through timely responses and proper documentation.

Do I need to renounce my original nationality?

That depends on your country. Spain requires renunciation in some cases, but has bilateral agreements with several nations. Legal advice from Marfour can clarify this based on your situation.

Can I apply online?

Yes. The Spanish government now allows submission of naturalization applications online. Marfour’s team can assist you with the secure electronic filing and tracking of your application.
