Summary
Spanish nationality by residence normally requires ten years of legal, continuous residence immediately before the application. This page covers that default period. It most often applies to people who do not qualify for the Civil Code's five-, two-, or one-year reduced periods or for nationality by origin or option.
The applicant must also prove good civic conduct and sufficient integration into Spanish society. Approval is discretionary within the statutory framework and may be denied for reasoned public-order or national-interest grounds. A grant does not take effect until the required oath/promise, declaration, and Civil Registry registration are completed within 180 days after notification.
Eligibility
Ten years of qualifying residence
Residence must be legal, continuous, and immediately before filing. Time in a tourist stay, an irregular situation, or a student estancia does not ordinarily count as nationality residence. A pending renewal can be complex if there was a gap, so build the timeline from official decisions and cards rather than assuming that physical presence alone is enough.
Spanish nationality authorities assess continuity independently from immigration renewal rules. Long or frequent absences can raise a continuity problem even if an immigration permit remained valid. Passport history, travel records, municipal registration, work or study history, tax records, and family-life evidence can help explain residence.
Before using ten years, check whether a shorter period applies: five years for a person recognized as a refugee; two years for nationals by origin of Ibero-American countries, Andorra, the Philippines, Equatorial Guinea, or Portugal, and for Sephardic applicants; or one year for one of the Article 22.2 cases.
Conduct and integration
The applicant must show good civic conduct, assessed more broadly than simply having no current conviction, and sufficient integration. Adults generally provide civil and criminal records and take the Cervantes Institute CCSE civic test and DELE Spanish test at A2 or higher unless an exemption, substitute qualification, or approved dispensation applies. Nationals of countries where Spanish is an official language are generally exempt from DELE, not automatically from CCSE.
Documents commonly include the full current and prior passports covering the required period, birth record, foreign criminal record, fee, residence and registration evidence, and exam/dispensation proof. Records for a special fact such as marriage, refugee status, or ancestry are unnecessary to the ten-year basis unless separately relevant. Foreign documents normally require legalization/apostille and official translation.
What This Route Allows
After approval, timely completion of Article 23 formalities, and Civil Registry registration, the applicant becomes Spanish and can obtain Spanish identity and passport documents. Spanish nationality also carries EU citizenship rights.
A person over 14 who can make the declaration must swear or promise fidelity to the King and obedience to the Constitution and laws. The Civil Code generally also requires a declaration renouncing the previous nationality, except for nationals of countries listed in Article 24.1 and Sephardim of Spanish origin. That Spanish declaration and whether another country actually ends its nationality are separate legal questions.
Nationality acquired by residence is not generally classified as nationality of origin. Future residence abroad, exclusive use of another nationality, or other conduct can raise retention or loss rules, so new citizens living abroad should obtain official consular guidance.
What This Route Is Not
- It is not a residence permit or an entry route to Spain.
- Ten years of physical presence is not enough without qualifying legal, continuous residence.
- Student stay time does not ordinarily satisfy this clock.
- Approval is not automatic on the ten-year anniversary.
- Spain's renunciation declaration should not be described as automatically canceling the other nationality under that other country's law.
Next Steps
- Rule out nationality by origin, option, or an Article 22 reduced residence period.
- Build a ten-year table of residence authorizations, renewals, addresses, and every absence from Spain.
- Resolve gaps, student-status periods, and extended or frequent absences before filing.
- Obtain the CCSE and DELE A2 credentials, or document the exact exemption/substitute/dispensation.
- Gather complete passports, birth and criminal records, residence evidence, fee evidence, and properly legalized and translated foreign documents.
- File through the Ministry of Justice's current electronic or permitted registry procedure and monitor notices.
- If granted, complete the oath/promise, any required renunciation declaration, and Civil Registry registration within 180 days.
