How to Get Spanish Citizenship: The Main Routes, the Real Timelines, and What to Consider First
For many people building a life in Spain, citizenship is the long-term goal.
It offers stability, freedom of movement within the EU, and the reassurance of knowing your future here is secure. But Spanish nationality law is not a single, simple path. The correct route depends entirely on your relationship to Spain — whether through family, residence, marriage, or another legally recognised connection.
This guide explains the main citizenship options available today, what has changed in recent years, and how to think about the process strategically.
First, an important distinction
When people talk about “getting Spanish citizenship”, they are often describing very different legal routes.
Broadly speaking, the main paths are:
citizenship by descent / origin
citizenship by option
citizenship by residence (naturalisation)
Each has different rules, different qualifying conditions, and very different timelines.
1. Citizenship by descent or origin
This is the strongest route when it applies.
Spanish nationality law gives nationality by origin to certain people from birth, especially where there is a direct parental connection to Spain. In practical terms, this often means that if your mother or father was Spanish, your position should be reviewed first under the rules for nationality by origin or by option before looking at any residence-based route.
This route is often the most attractive because it may not require:
prior residence in Spain
language exams
a long waiting period based on immigration status
That said, not all ancestry cases are equal. A Spanish parent is very different from a Spanish grandparent in legal terms, and the correct route depends on the facts of your case.
2. Citizenship by option
Nationality by option is a special legal right available in specific circumstances set out in the Civil Code.
According to the Ministry of Justice, this right applies, among others, to:
people who are or have been under the parental authority of a Spanish national
those whose father or mother was originally Spanish and born in Spain.
This is not the same as ordinary naturalisation. It is a specific family-based route, and when it applies it can be significantly simpler than citizenship by residence.
3. Citizenship by residence (naturalisation)
For many expats, this is the route that eventually applies.
Nationality by residence requires that you have lived in Spain for the legally required period in a way that is legal, continuous, and immediately prior to the application, and that you can show both good civic conduct and sufficient integration into Spanish society.
The residence period depends on your situation.
Standard route: 10 years
This is the default rule for most applicants.
Reduced route: 2 years
This applies to nationals of many Ibero-American countries, as well as certain other categories recognised by Spanish law.
Reduced route: 1 year
This shorter residence period can apply in several special cases, including some applicants married to a Spanish citizen and some family-origin situations recognised by law.
The key point is this:
Residence-based citizenship is not just about time.
It is about lawful residence, continuity, documentation, and integration.
Citizenship by marriage: one of the fastest residence-based routes
If you are married to a Spanish citizen, Spanish law may allow you to apply for nationality after one year of legal residence in Spain, rather than waiting ten years. This is one of the fastest residence-based routes available.
It is important to note, however, that marriage and pareja de hecho are not treated the same way for nationality purposes. Marriage can reduce the residence period to one year; a registered civil partnership does not generally create that same shortcut under nationality law.
The Democratic Memory Law route has now closed
For a period of time, the Democratic Memory Law created additional nationality options for certain descendants of Spaniards.
That filing window has now closed. Spanish consular notices confirm that the deadline for requesting appointments under that route ended on 22 October 2025.
This means that for most new applicants today, that route should no longer be treated as generally open. Current strategy should focus on the routes that remain active under the Civil Code and nationality-by-residence rules.
What does the residence route usually involve?
If you are applying through residence, the process usually includes:
maintaining the required period of lawful residence
preparing civil and criminal record documents
demonstrating integration
paying the nationality application fee
completing the final oath or promise once approved.
For many applicants, integration also means completing the relevant exams, depending on whether exemptions apply.
What is the current application fee?
The Ministry of Justice states that nationality applications by residence are subject to a fee, and the current amount is €104.05.
This is just the official fee. In practice, total costs may also include translations, apostilles, criminal record certificates, exam fees, legal advice, and document renewals.
How long does the whole process take?
This is one of the most important questions — and one of the most misunderstood.
Even once you qualify to apply, citizenship is not immediate. The full process usually includes:
qualifying under the correct route
gathering and preparing documents
submitting the application
waiting for the decision
taking the oath or promise
registering the nationality and obtaining Spanish documents.
So when people say “one year” or “two years”, that usually refers to the residence qualification period, not the full end-to-end timeline.
In reality, the overall journey is often longer.
Dual nationality: can you keep your existing passport?
This depends on the route you use and the country you already hold nationality from.
Spain formally allows dual nationality in certain cases and with certain countries, while in others the rules are more restrictive. This is an area where legal theory and practical reality do not always align neatly, especially depending on your original nationality.
If dual nationality matters to you, it is wise to review this carefully before applying.
The most strategic way to think about Spanish citizenship
Before doing anything else, ask yourself three questions:
1. Do I have a family-based route?
If you have a Spanish parent, or a qualifying option route, this should be reviewed first. It may be simpler and faster than a residence-based application.
2. Am I relying on a route that has already closed?
If your claim is based on the Democratic Memory Law, check timing very carefully, because the appointment deadline passed in October 2025.
3. If I need residence, which residence route applies?
The difference between one year, two years, five years, and ten years is enormous. Getting this wrong can cost years.
In practice, what are the main citizenship routes today?
For most people, the realistic pathways now are:
descent / origin through a Spanish parent
option, where the Civil Code allows it
residence, usually after 10 years
residence after 2 years for certain nationalities
residence after 1 year for certain special cases, including some spouses of Spanish citizens.
That is the practical framework most applicants are working within today.
