Spanish Citizenship by Descent: Every Route Open in 2026 (and the Ones That Closed)

If one of your parents was born Spanish, you are probably a Spanish citizen already. You just need the paperwork to prove it. If the Spanish ancestor is a grandparent or great-grandparent, the answer gets more complicated, and timing matters far more than most blogs admit. Some doors are wide open in 2026. Others closed recently, and a few closed for good. This guide walks through every route to Spanish citizenship by descent, what documents you need, where to file, how long it really takes, and what happens to your US passport along the way.

Who Qualifies for Spanish Citizenship by Descent

Spanish nationality law runs on bloodline, not birthplace. Being born in Miami or Los Angeles gives you nothing by itself. What counts is who your parents were when you were born, and in some cases, who their parents were. There are three descent-based routes worth knowing, and each has very different rules.

Children of Spanish Nationals: Automatic Citizenship

Under Article 17 of the Spanish Civil Code, anyone born to a Spanish mother or father is Spanish from birth. It does not matter where you were born or whether your parents ever registered you. The citizenship exists; the consulate just has not recorded it yet.

The fix is registration, not application. You file your birth with the civil registry at the Spanish consulate that covers your state, along with your parent’s proof of Spanish nationality and your own birth certificate. Once the consulate inscribes your birth, you can request a Spanish passport.

One wrinkle trips up a lot of American families: the parent must have held Spanish nationality at the time of your birth. If your mother naturalized as a US citizen and lost her Spanish nationality before you were born, you fall into a different category. Article 20 of the Civil Code gives an option to nationality for people whose father or mother was originally Spanish and born in Spain, and Article 20.3 sets no age limit on exercising that particular option (Ministerio de Justicia). Plenty of adult children of Spanish emigrants use this route today.

The Grandchildren Law: Where It Stands Now

The Democratic Memory Law (Law 20/2022, published in the BOE) opened the widest descent window Spain has offered in decades. Through its eighth additional provision, grandchildren and children of Spaniards who lost or renounced their nationality because of exile, dictatorship, or because Spanish women historically lost nationality by marrying foreigners could claim citizenship of origin, no residency required.

Here is the hard part. The application window opened in October 2022 and, after a one-year extension approved by the Spanish government, closed to new appointment requests on October 22, 2025 (Ministerio de Asuntos Exteriores). As of mid-2026, no further extension has been announced, and consular notices confirm the door is closed to new requests. If you booked your appointment before the deadline and hold proof it was requested in time, your case is still valid and consulates continue processing the backlog. If you missed it, this specific route is shut unless Spain reopens it by new legislation, which advocacy groups have called for, though nothing is confirmed.

Missing the window does not mean you are out of options. The two-year residency route below covers many of the same families, especially Latin Americans.

The Sephardic Route: Closed

Spain’s law for descendants of Sephardic Jews expelled in 1492 (Law 12/2015) made headlines worldwide, but it is no longer available. The application window closed in October 2019, and the final deadlines for completing pending files lapsed in 2021 (Ministerio de Justicia). Sephardic descendants can still reach citizenship the classic way: Article 22.1 of the Civil Code grants people of Sephardic origin the same reduced two-year residency requirement it gives Ibero-American nationals.

The Two-Year Residency Shortcut for Latin Americans

Spain~24% expat tax

This is the route most Americans with Latin American heritage overlook, and for many families it is the strongest card on the table.

Article 22 of the Spanish Civil Code cuts the standard ten-year residency requirement for naturalization down to two years for nationals of origin of Ibero-American countries, plus Andorra, the Philippines, Equatorial Guinea, and Portugal. If you hold citizenship of Mexico, Colombia, Argentina, Peru, the Dominican Republic, or almost any other Latin American country, you can generally naturalize as Spanish after just two years of legal, continuous residence in Spain.

Two details matter enormously:

• The residence must be legal, continuous, and immediately before you apply. Tourist stays do not count. You need an actual residency permit, and for people with passive income or remote work, the non-lucrative visa is the most common entry point. Two renewable years on that visa can satisfy the requirement.
• Dual nationality with your Latin American passport survives. Under Article 24 of the Civil Code, acquiring or holding the nationality of an Ibero-American country does not cost you Spanish nationality, so a Mexican or Argentine citizen who becomes Spanish keeps both.

For a Mexican-American in Texas or a Colombian-American in New York, the math is striking. Your Latin American passport, which you may already hold or can claim through your own parents, turns Spanish citizenship from a distant dream into a two-year project.

Documents You Will Need

Every descent route runs on paper, and Spanish authorities are strict about format. Expect to gather:

• Your ancestor’s Spanish birth certificate (certificación literal de nacimiento) from the Spanish Civil Registry. If your parent or grandparent was born in Spain, the registry of their birth town issues it. Ordering from the US is possible through the Ministry of Justice’s online civil registry service (sede.mjusticia.gob.es).
• Birth and marriage certificates linking each generation. Your birth certificate, your parent’s, and marriage certificates that explain any name changes along the chain.
• Apostilles. Every US-issued document needs a Hague apostille from the Secretary of State of the issuing state. Spain will not accept a plain certified copy.
• Sworn translations. Documents in English must be translated by a sworn translator (traductor jurado) accredited by Spain’s Ministry of Foreign Affairs (exteriores.gob.es). A regular certified translation from a US agency usually gets rejected.
• Criminal record checks for naturalization routes (FBI background check, apostilled and translated), plus the DELE A2 Spanish exam and the CCSE culture test run by the Instituto Cervantes for the two-year residency path. Nationals of Spanish-speaking countries are exempt from the DELE A2 language exam.

Start with the ancestor’s Spanish birth certificate. It is the keystone document, and if the town’s records were lost or the details in family lore turn out to be wrong, you want to know before you spend money apostilling everything else.

Where to Apply

If you live in the United States, descent claims go through the Spanish consulate with jurisdiction over your state. Spain runs consulates general across the US, in cities including Washington DC, New York, Boston, Chicago, Houston, Miami, Los Angeles, and San Francisco, plus one in San Juan, Puerto Rico (exteriores.gob.es). You cannot pick the one with the shortest line; jurisdiction is fixed by where you live.

Each consulate houses a civil registry office that handles birth inscriptions and nationality options. Appointments are booked online and, at the busier consulates like Miami and Los Angeles, slots disappear fast. Checking the booking system early in the morning, midweek, genuinely helps.

Naturalization by residency works differently. You apply from inside Spain through the Ministry of Justice’s electronic platform, not through a consulate, because you must already be a legal resident.

How Long Does It Really Take?

Honest numbers, because this is where expectations go to die:

• Birth registration for children of Spaniards: a few weeks to several months after your appointment, depending on the consulate’s workload.
• Article 20 option cases: often six months to over a year, since files route through Spanish registries for verification.
• Democratic Memory Law files: consulates received very large volumes of applications before the 2025 deadline. Pending cases have commonly taken one to two years to resolve, and the backlog is still being worked through in 2026.
• Naturalization by residency: Article 21 gives the government one year from the end of the file to decide, but real-world resolution has frequently run longer, and after approval you still swear the oath (jura or promesa) and register the acquisition before getting a passport.

None of this should scare you off. It should just shape your plan. People who gather documents while waiting for appointments cut months off the total.

Do You Have to Give Up US Citizenship?

This question stops more Americans than any other, so let’s handle it carefully.

Under Article 23 of the Civil Code, most adult foreigners acquiring Spanish nationality must declare that they renounce their prior citizenship. Nationals of the countries listed in Article 24.1, meaning Ibero-American countries, Andorra, the Philippines, Equatorial Guinea, and Portugal, are exempt, and French nationals are exempt too under the Spain-France nationality convention in force since 2022, so all of them can hold both openly. Americans without one of those nationalities are asked to make the renunciation declaration before Spanish authorities.

Here is the part that matters: that declaration is made under Spanish law, in Spain, to Spanish officials. The US State Department states that a US citizen loses citizenship only through a potentially expatriating act performed voluntarily and with the intent to relinquish US nationality, and that formal renunciation of US citizenship must be done in person before a US consular officer abroad. Reflecting that framework, many Americans who have gone through Spanish naturalization report keeping their US passports, on the view that the Spanish declaration is not the formal US renunciation process. This is a genuinely nuanced legal area with no guarantees, and anyone weighing it should get advice on both the Spanish and American sides before acting. Our partners at MySpainVisa cover the Spanish side in depth in their guide to dual citizenship in Spain.

Also worth repeating: if you are Spanish through Article 17 (born to a Spanish parent), you were never “acquiring” a new nationality at all. You were always Spanish, so no renunciation question arises.

Can I Get Spanish Citizenship Through My Grandparents in 2026?

Through a direct grandparent claim, generally no longer. The Democratic Memory Law window closed to new appointment requests in October 2025. What remains open: if your parent claims Spanish nationality first (for example through Article 20 as the child of someone originally Spanish and born in Spain), you may then be able to claim through your parent, effectively working through the generations one at a time. And if you hold a Latin American nationality, the two-year residency route is open regardless of when your grandparents left Spain. A case review is worth more than guessing here, because the right sequence of filings differs family by family.

How Much Does Spanish Citizenship by Descent Cost?

Government fees are modest. Consular birth registrations and nationality options carry small administrative charges, and the naturalization application fee has typically sat in the low hundred-euro range. The real costs are the supporting pieces: apostilles (roughly $5 to $20 per document depending on the state), sworn translations (often $40 to $80 per page), the DELE and CCSE exam fees if they apply to you, and legal help if your case has complications like name discrepancies or missing records. Budget a few hundred dollars for a clean, simple case and more if a lawyer needs to reconstruct a paper trail. Exact fees change, so confirm the current figures before you file.

FAQ: Spanish Citizenship by Descent

Does Spain allow dual citizenship with the United States?

Not formally, for most Americans. Spain asks non-exempt naturalization applicants to declare renunciation of their prior nationality, while nationals of Ibero-American countries and a few others are exempt. The US, for its part, only recognizes loss of citizenship through the formal expatriation process before US authorities. Read the dual citizenship section above and get case-specific advice before deciding.

My great-grandfather was Spanish. Do I qualify?

Not directly through any current route in most cases. Great-grandchildren generally fell outside the Democratic Memory Law’s scope, and that window has closed anyway. Check whether an intermediate generation (your grandparent or parent) can claim first, or whether you hold or can obtain a Latin American nationality for the two-year residency path.

Do I need to speak Spanish?

For birth registration and Article 20 options, no language exam applies. For naturalization by residency, you need the DELE A2 certificate unless you are a national of a Spanish-speaking country, plus the CCSE civics test, both run by the Instituto Cervantes.

Can my kids get citizenship too?

Yes, and this is the quiet payoff. Once you are Spanish, children born after that point are Spanish from birth, and minor children can generally opt in through the option procedures in Articles 20 and 22. One successful claim often converts an entire family line.

Other Digital Nomad Destinations to Consider

Citizenship is the long game. If you want to live in Spain sooner, or you are still comparing options, these guides are the logical next step:

• Living in Spain as an American: what daily life, taxes, and healthcare actually look like once you land.
• Moving to Spain from the USA: the full relocation playbook, visa by visa.
• Spain retirement visa: the passive-income route most future citizens use for their qualifying residency years.

Spain keeps coming out on top for one simple reason: it is one of the few countries where heritage can shortcut the entire immigration process. If your family tree points to Spain or Latin America, that is leverage most expats never get. And you do not have to untangle the Civil Code alone. The immigration lawyers at MySpainVisa handle citizenship and residency cases end to end, from tracking down a grandmother’s birth certificate in a village registry to standing with you at the jura. Tell them your family story and they will tell you which door is open.
