Why Dual Citizenship in Spain is the Goal for 2026

Acquiring Spanish citizenship is more than just getting a new passport; it’s unlocking the right to live, work, and travel freely across the 27 countries of the European Union. However, for many expats, the primary concern is: “Will I have to renounce my birth citizenship?”

As we move into 2026, new regulations like the Democratic Memory Law and updated bilateral agreements (such as the recent one with France) have changed the landscape. At My Spain Visa, we specialize in helping citizens from the US, UK, Canada, and Ibero-American countries navigate these complexities with a 99% success rate in residency applications.

Does Spain Allow Dual Citizenship?

Yes, Spain allows dual citizenship, but eligibility depends on your country of origin. You can legally obtain Spanish dual citizenship without renouncing your current passport if you are a national of an Ibero-American country, Portugal, Andorra, the Philippines, Equatorial Guinea, or France.

If you are wondering, “Does Spain allow dual citizenship with the US?”, the formal process requires naturalized US citizens to renounce their nationality, although specific legal nuances allow many to maintain both passports in practice. Understanding how to get dual citizenship in Spain is essential for expats seeking the benefits of an EU passport while maintaining their original roots.

Which Countries Have Dual Nationality Agreements with Spain?

Understanding the nationality of Spain and its specific requirements is the first step for any expat. The Spanish Civil Code establishes different paths based on your country of origin, granting significant advantages to those with historical ties to the Spanish nation.

The Comprehensive List of Eligible Countries

Below is the complete list of nations that have bilateral agreements with Spain, allowing you to obtain Spanish dual citizenship without renouncing your birth nationality.

*Note: While French citizens can now keep both passports, they generally follow the standard 10-year naturalization timeline unless qualifying through marriage (1 year).

The “Renunciation” Myth: Dual Citizenship for US, UK, and Canadian Citizens

If your country is not on the list above, such as the United States, United Kingdom, or Canada, Spanish law technically requires you to “renounce” your original nationality during your naturalization ceremony. This is one of the most searched topics in US Spain dual citizenship.

How it Works in Practice

For many, this “renunciation” is a formal declaration made before a Spanish judge at the Civil Registry. However, there is a significant legal nuance:

• The Spanish Side: You sign a document stating you renounce your previous nationality to satisfy Spanish dual nationality requirements.
• The Home Country Side: Countries like the USA do not automatically recognize this Spanish declaration. To truly lose US citizenship, you must perform a separate, intentional act at a US consulate.
• The “Effective” Dual Status: Many expats maintain two parallel legal lives, acting as a Spaniard within the EU and as a citizen of their home country elsewhere.

Expert Warning: While many effectively keep both passports, this creates legal and tax complexities. Navigating how to apply for dual citizenship in Spain as a “non-agreement” national requires strategic legal planning to avoid the risk of losing your status in the future.

Spanish Dual Citizenship for US Citizens: The “Renunciation” Myth

One of the most frequent questions we receive at My Spain Visa is: “Does Spain allow dual citizenship with the US?”. Technically, the answer in the Spanish Civil Code is “no” for non-treaty countries, but in practice, the reality for thousands of US, UK, and Canadian citizens is very different.

The “Renunciation” at the Civil Registry

When you reach the Spanish citizenship requirements (usually after 10 years of legal residence, or just 1 year if you qualify for Spanish citizenship by marriage), you must attend a naturalization ceremony. During this process, you are required to formally “renounce” your previous nationality before a Spanish official.

However, here is why it is considered a “myth”:

• A Formal Pledge, Not a Practical Loss: This renunciation is a declaration made to the Spanish government to satisfy Spain’s dual nationality laws.
• Lack of Notification: Spain does not notify the US Department of State, the UK Home Office, or the Canadian government that you have signed this declaration.
• Home Country Laws: For the United States, citizenship is a constitutional right. To lose it, you must perform a “voluntary and intentional” act of relinquishment at a US Consulate specifically to give up your US status. Simply signing a paper in a Spanish registry typically does not meet this threshold.

Can You Apply for a Dual Spanish Passport?

Yes. Once the process is complete, you will be able to apply for a Spanish passport. This means you will effectively hold two passports:

1. Your Spanish Passport: To move freely within the EU and enter/exit Spain.
2. Your Original Passport: To enter your home country (as required by US and UK law for their citizens).

The Reality of “De Facto” Dual Status

Because of this legal disconnect, many expats live with dual Spanish citizenship. They are recognized as Spanish in Spain and as Americans in the US. In some complex cases involving multiple ancestries, some even explore if Spain allows triple citizenship, which follows the same practical “don’t ask, don’t tell” logic between the involved nations.

Important Legal Note: While many maintain both nationalities, this “de facto” status has implications for taxes, military service, and diplomatic protection. If you are looking for how to become a citizen of Spain without jeopardizing your original status, a consultation with a Spanish dual nationality expert is vital to ensure you are protected in both jurisdictions.

Ways to Acquire Dual Spanish Citizenship in 2026

Spanish law provides four primary legal pathways to becoming a citizen. Selecting the right one is critical, as it determines how many years you must reside in the country and what documentation you will need to provide.

Citizenship by Descent (Ley de Nietos / Democratic Memory Law)

Applying by descent is often the most direct route, as it is based on bloodline (jus sanguinis) rather than residency time.

• Standard Descent: You qualify if at least one parent was a Spanish national at the time of your birth, or if you were adopted by Spanish citizens before the age of 18.
• The Democratic Memory Law (Ley de Memoria Democrática): This special law, often called the “Grandchildren Law,” was specifically designed for descendants of Spaniards who suffered exile for political or ideological reasons.
• 2026 Status: While originally set to expire sooner, the Spanish government extended the application deadline for the Democratic Memory Law. Standard provisions for direct descendants continue to apply in 2026, often allowing applicants to secure citizenship without ever having to live in Spain.

Citizenship by Residency (The 1/2/5/10 year rules)

This is the most common path for those who move to Spain for work or lifestyle. To qualify, your residency must be legal, continuous, and immediately prior to the application.

• 10 Years (General Rule): The standard requirement for most foreigners (e.g., US, UK, Canada).
• 5 Years: Required for those recognized as refugees.
• 2 Years: An accelerated timer for nationals of Ibero-American countries, Portugal, the Philippines, Andorra, Equatorial Guinea, or individuals of Sephardic origin.
• 1 Year: A special fast-track for those born in Spanish territory, widows/widowers of Spaniards, or those who have been under the legal guardianship of a Spanish citizen for two consecutive years.
• Crucial Note: Time spent on a Student Visa does not count toward these residency requirements; it is considered a “stay” (estancia), not residency.

Citizenship by Marriage

Marrying a Spanish national is widely considered the quickest route to a passport for non-Ibero-American citizens.

• The 1-Year Rule: You can apply for citizenship after just one year of legal residency in Spain, provided you have been married and cohabiting with your Spanish spouse for that entire year.
• Requirements: You must have a valid residence permit, a clean criminal record, and a marriage certificate registered in the Spanish Civil Registry.
• Spanish nationality Exam: Like most routes, you must still pass the CCSE (culture) and DELE A2 (language) exams, unless you are from a Spanish-speaking country.

Other Visas (Digital Nomad, and NLV)

While these visas do not automatically grant citizenship, they are the “engines” that provide the legal residency required to start your timer.

• Digital Nomad Visa: Allows remote workers to live in Spain; these years count toward the residency requirement for citizenship.
• Non-Lucrative Visa (NLV): Ideal for retirees or those with passive income. After 5 years, you can transition to permanent residency, and after 10 years (or 2 for Ibero-Americans), you can apply for citizenship.

Requirements to Apply for Dual Nationality

Before you begin the process of how to apply for dual citizenship in Spain, you must ensure you have a complete “expediente” (application file). While specific cases might require extra paperwork, these are the universal Spanish citizenship requirements you will need to meet in 2026:

• Valid Passport: Your current original passport (and copies of every single page, including blank ones).
• Current Residency Card (TIE): You must hold a valid legal residency status in Spain at the time of application.
• Criminal Record Certificate: From your country of origin and any country you have lived in for the last 5 years (duly legalized and translated).
• Birth Certificate: An official, legalized copy from your home country.
• Certificate of Census (Padrón): Proving your current address in a Spanish municipality.
• DELE A2 & CCSE Exams: Proof of passing the Spanish language (DELE A2) and cultural/constitutional knowledge (CCSE) exams.
  • Note: Nationals from Spanish-speaking countries are exempt from the DELE exam.
• Proof of Paid Fees: You must pay the official Spanish nationality fee (currently around €105) before submitting.
• Marriage Certificate (Optional): Only if you are applying through the fast-track citizenship by marriage route.

The Cost of Securing Dual Citizenship in Spain: What You Need to Invest

Applying for dual nationality in Spain is not just about a single fee; it is a financial and legal project that requires precision. In 2026, many applicants fail because they underestimate the hidden costs of a DIY application.

Estimated Costs for Your Spanish Dual Nationality Application

While we provide personalized quotes at My Spain Visa to fit your specific case, these are the mandatory administrative expenses you must anticipate:

• Official Government Fee (Tasa 790-026): €104.50. This is a non-refundable tax to the Ministry of Justice. If your application is denied due to a technicality, this money is lost forever, and you must pay again to restart.
• Spanish Nationality Exams (CCSE & DELE): * CCSE (Culture): Approximately €85.
  • DELE A2 (Language): Approximately €124 to €138.
  • Risk: Failing these exams or letting the certificates expire before submission can delay your how to become a Spanish citizen timeline by months.
• Legalization and Sworn Translations: For cases like US Spain dual citizenship, you must legalize (Apostille) and translate every document. These “sworn translations” can cost between €50 and €100 per document, and a single missing stamp can lead to an immediate rejection.
• Hidden Renewal Risks: Most foreign documents, such as criminal record certificates, have a very short validity (often 90 days). If you don’t submit a perfect file quickly, you may be forced to restart the entire document gathering process, doubling your costs.

Processing Times: How Long to Get Your Dual Spanish Passport?

The path to apply for a dual Spanish passport is legally set to take 12 months, but the reality in 2026 is far more complex.

Why DIY Applications Often Face “Negative Silence”

• Standard Manual Filing: If you submit your file without professional digital tools, your application enters a “black hole.” It is common for these cases to take 18 to 24 months or result in “Administrative Silence,” which in Spain typically means a rejection.
• Digital Lawyer Submission (Fast-Track): By using our professional digital registry, we can often reduce the wait to 3 to 10 months.
• The 180-Day Trap: This is the biggest fear for our clients. Once your dual nationality in Spain is approved, you have exactly 180 days to complete the “Oath of Allegiance”. If you miss this deadline because you couldn’t secure an appointment, your citizenship is revoked, and you may have to wait another 10 years to qualify again.

Don’t leave your future to chance. A small mistake in your Spain dual citizenship requirements can cost you years of your life and thousands of euros in renewals.
