Dual Citizenship Spain: Who Qualifies and How It Works
Spain allows dual citizenship with select countries under bilateral agreements. Learn which nationalities qualify, what happens if yours doesn't, and the complete process for obtaining Spanish citizenship without losing your passport.
What is Dual Citizenship in Spain?
Dual citizenship means holding the nationality of two countries simultaneously. Spain's approach to dual citizenship is unique: it generally requires you to renounce your previous nationality to obtain Spanish citizenship, but makes exceptions for countries with bilateral agreements.
Spain has signed treaties with specific nations recognizing the right to hold Spanish citizenship without giving up your original nationality. These agreements primarily involve Ibero-American countries (former Spanish colonies), but also include Portugal, Andorra, France, and the Philippines.
For nationals of countries without such agreements—including the UK, USA, Canada, Australia, and most others—Spain legally requires you to renounce your previous citizenship as a condition of obtaining Spanish citizenship. However, your home country may not recognize this renunciation, meaning you could technically retain dual nationality even if Spain only recognizes your Spanish citizenship.
This distinction is crucial: Spain's recognition and your home country's recognition operate independently. Always check with your home country's embassy before beginning the Spanish citizenship process.
Countries Eligible for Dual Citizenship with Spain
These nations have bilateral agreements with Spain allowing citizens to hold Spanish citizenship alongside their original nationality. This list includes most Ibero-American countries plus selected European and Asian nations.
Important: Nationals from the UK, USA, Canada, Australia, South Africa, and most other countries must legally renounce their previous nationality to obtain Spanish citizenship. However, many countries (including the UK and USA) do not recognize renunciation and may allow you to retain your original passport. Check with your home country's embassy before starting the process.

How Dual Citizenship Works in Practice
Understanding the practical implications of holding dual Spanish citizenship is essential before pursuing it.
Two Passports
If you hold dual citizenship with Spain, you may have two valid passports. Some countries require you to enter on your passport from that nation. Spain generally expects you to use your Spanish passport when traveling to Spain, though this isn't strictly enforced.
Tax Obligations
Spain taxes residents on worldwide income, regardless of nationality. If you become a tax resident of Spain, you'll owe Spanish income tax. Most countries have tax treaties with Spain to avoid double taxation, but obligations vary by country of origin. Consult a tax advisor for your specific situation.
Military Service
Spain abolished mandatory military service in 2001, so dual Spanish citizenship carries no military obligation from Spain. However, your country of origin may have military service requirements for its citizens. Some countries exempt those living abroad; others do not.
Voting Rights
As a Spanish citizen, you can vote in Spanish elections and EU elections (if you register). Voting in your country of origin depends on that country's laws regarding citizens abroad.
Rights and Responsibilities
Dual citizenship means you enjoy all rights of both countries—access to healthcare, education, employment protections, and state benefits (subject to residency requirements). You're also responsible for following both countries' laws.
Travel and Residency
Spanish citizenship grants you EU freedom of movement—you can live and work in any EU country without visa restrictions. Your second citizenship may provide additional travel advantages depending on the nation.
How to Get Dual Citizenship in Spain
The path to Spanish citizenship involves meeting residency, language, and civics requirements. Here's the standard process for most applicants.
Residency Requirements
The residency period depends on your category. Most foreign nationals must reside in Spain for 10 consecutive years. However, treaty-based applicants (those with bilateral agreements) may qualify after 2 years. Refugees and stateless persons qualify after 5 years.
Language Requirement (DELE A2)
You must demonstrate Spanish language proficiency equivalent to A2 level on the Common European Framework. The official DELE (Diplomas de Español como Lengua Extranjera) A2 exam, administered by Instituto Cervantes, is the standard proof. Private academies also offer preparation courses.
Civics Test (CCSE)
The Constitución y Sociedad Española (CCSE) test covers Spanish government, constitution, history, and society. It's administered by the Instituto Cervantes and consists of 25 multiple-choice questions covering Spanish history, civic values, and constitutional knowledge.
Document Preparation
You'll need birth certificates, marriage/divorce documents (if applicable), police clearance certificates, medical exams, financial documentation, and proof of residency. All non-Spanish documents require official translation and apostille certification.
Application Submission
Submit your application to your provincial immigration office (Delegación Provincial de la Dirección General de Migraciones) or consulate if abroad. Processing typically takes 3-6 months, though it can extend longer.
Oath of Allegiance
Upon approval, you'll attend an oath ceremony where you swear allegiance to the Spanish Constitution. Following the ceremony, you receive your citizenship certificate and are eligible to apply for a Spanish passport.
Special Cases & Exceptions
Certain situations may allow streamlined or alternative paths to Spanish dual citizenship.
Children and Spanish Nationality by Descent
Children born abroad to at least one Spanish parent automatically acquire Spanish citizenship. They may retain their other parent's nationality if that country allows dual citizenship. Children born in Spain to foreign parents can claim Spanish nationality through a declaration within 3 years of reaching age 18.
Marriage to a Spanish National
Marrying a Spanish citizen reduces the residency requirement to 1 year instead of 10. You must still pass language and civics requirements. Language requirements may be waived if you can document prior Spanish language education.
Sephardic Jewish Citizenship Program (Closed): Spain offered a special citizenship program for descendants of Sephardic Jews expelled in 1492, requiring no residency. The official program closed on October 1, 2019. Limited extensions may still be available for those who initiated applications before the deadline—contact the Spanish Ministry of Justice for details.

Frequently Asked Questions
Get quick answers to common questions about dual citizenship with Spain.
Which countries can hold dual citizenship with Spain?
Spain allows dual citizenship with countries that have bilateral agreements, including most Ibero-American nations (Argentina, Brazil, Mexico, Colombia, Peru, and others), Portugal, Andorra, France (limited), and the Philippines. Citizens of these countries can hold Spanish citizenship alongside their original nationality without legal penalty from Spain.
Do UK and US citizens have to renounce their nationality to get Spanish citizenship?
Spain legally requires UK, US, Canadian, Australian, and most other nationals to renounce their previous nationality to obtain Spanish citizenship. However, many countries (including the UK and USA) do not recognize renunciation from their citizens. They may allow you to retain your original nationality even after formally renouncing it to Spain, meaning you could legally hold dual nationality. Always check with your home country's embassy.
What is the process for obtaining Spanish citizenship?
The typical process involves: meeting a residency requirement (usually 3-10 years depending on nationality), passing the DELE A2 Spanish language exam, passing the CCSE civics test, gathering required documents, submitting your application to immigration authorities, and attending an oath-taking ceremony. Treaty-based applicants may qualify after just 2 years of residency.
Can children born in Spain to foreign parents hold dual citizenship?
Yes, if at least one parent is a Spanish national or legally resident in Spain, and if the parents' home country also recognizes dual citizenship. Children born in Spain automatically acquire Spanish nationality at birth if one parent is Spanish. If both parents are foreign but legally resident, the child can declare Spanish nationality within 3 years of reaching age 18.
What happens to my original passport after obtaining Spanish citizenship?
If your home country recognizes dual citizenship (like Argentina or Mexico), you keep both passports and can use either for travel. If your country doesn't recognize dual citizenship, your original passport may become invalid, though you may still be considered a citizen by your home country. Always check with your home country's embassy for their specific rules before starting the Spanish citizenship process.
Do I have to pay taxes in both countries if I hold dual citizenship with Spain?
Tax obligations depend on your residency status and where your income is sourced. Spain taxes residents on worldwide income. Most countries have tax treaties to avoid double taxation. However, you may still need to file returns in both countries. Consult a tax professional specializing in international taxation to understand your specific obligations.
What military service obligations come with Spanish dual citizenship?
Spain abolished mandatory military service in 2001, so holding Spanish dual citizenship carries no military obligation to Spain. However, dual citizens may face military obligations in their country of origin. Some countries exempt citizens living abroad; others do not. Check with your home country's government for their specific rules.
What is the Sephardic Jewish citizenship program?
Spain offered a special citizenship program for descendants of Sephardic Jews expelled in 1492, granting Spanish citizenship without residency requirements. The official program closed on October 1, 2019. Limited extensions may still be available for those who initiated applications before the deadline. Contact the Spanish Ministry of Justice for current eligibility details and any possible extensions.
