In short: there is no dual citizenship treaty between Spain and Russia. When naturalizing, Spanish law requires you to declare renunciation of your previous nacionalidad before the Registro Civil (civil registry), while Russia terminates its citizenship only through its own separate renunciation procedure. In practice people often end up keeping two passports — but that is a "second citizenship," not dual citizenship recognized by both countries, and your obligations remain in force in each jurisdiction.
Dual citizenship in the strict sense is a construct of an international treaty: two countries agree to mutually recognize both passports and divide taxes, military service and consular protection between themselves. Spain has signed such agreements only with Ibero-American countries. There is no such treaty with Russia, and none is planned in the foreseeable future.
Second citizenship is the factual situation where a person holds two valid passports, but each country sees only "its own." To Spain you are Spanish; to Russia, Russian. This is the regime the vast majority of naturalized people from Russia actually live under. Hence the practical takeaway: plan not for a "dual status" but for two separate sets of obligations.
The final step is an act at the Registro Civil: an oath of allegiance to the Constitution and the Crown plus a declaración de renuncia — a declaration renouncing your previous nationality. Without this formality, the record of your new status is not made.
The key nuance: the Spanish registry records your declaration but does not ask the Russian authorities to confirm that the renunciation procedure has actually been completed. Formally, the requirement is deemed fulfilled by the declaration itself. At the same time, the Spanish Civil Code leaves the state a lever: a naturalized citizen may lose Spanish status if, within the period set by the code after the oath, they use exclusively the citizenship they declared renounced. The rule is rarely applied, but it exists — and that is an argument against the advice to "just sign and forget."
Exempt from renunciation are citizens of Ibero-American states, Portugal, Andorra, the Philippines and Equatorial Guinea, as well as certain categories by origin. Russia is not on this list.
The oath in Madrid or Valencia does not by itself terminate Russian citizenship: Russia recognizes only its own procedure of voluntary renunciation through a consulate. Until it is completed, to Russia you remain a Russian citizen, required to enter and leave the country on your Russian international passport.
The second consequence: Russian citizens are obliged to notify the MVD (Ministry of Internal Affairs) of holding a foreign passport or residence permit. The procedure and deadlines are set by the citizenship law; separate rules apply to those permanently residing abroad — check the current wording on the ministry's official portal before traveling to Russia.
Spain counts not "years in the country" but years of legal, continuous residence on a residence card. For nationals of Russia, Belarus, Ukraine and Kazakhstan the general period applies.
| Applicant category | Required residence | Renunciation required? |
|---|---|---|
| Citizens of Russia and most third countries | 10 years | Yes, a declaration at the Registro Civil |
| Spouse of a Spanish citizen | 1 year | Yes |
| Recognized refugees | 5 years | Yes |
| Ibero-America, Portugal, Andorra, the Philippines, Eq. Guinea | 2 years | No — dual citizenship treaties |
Processing of the application itself takes another 1–2 years — this period should also be built into your plan. The procedure and exams are covered in detail on the page on Spanish citizenship.
Keep a separate eye on your absences: for long-term status the limit for a continuous absence is 6 months, and for total absences — 10 months. The Registro Civil judge assesses actual residence even more strictly; the topic is covered in the article on long absences from the country.
The calculator will show when you become eligible for long-term residence and when for the naturalization application: enter the month of your first card, your ground and family status — preferential categories are factored in automatically.
A common misconception is that a Spanish passport "switches" your taxes. In reality, tax status is determined by presence in the country: the threshold is 183 days in a calendar year, plus the center of economic interests. A resident declares worldwide income under IRPF (Spanish personal income tax) regardless of how many passports sit in the drawer. Rates and deductions are covered in the article on personal taxes, and the mechanics of residency — in the article on the 183-day rule. The special flat-rate regime for incoming workers 24% has no bearing on naturalization and by this stage has usually already run its course.
The generator will compile a personalized list of papers with apostilles and translations — based on your status ground and family composition, with no unnecessary items.
The full list of papers for the application is given in the answer on documents for a Spanish passport.
Each state sees only its own status: the Spanish consulate deals with you as a Spaniard, the Russian one as a Russian citizen, regardless of the second document.
No. Termination of Russian status is possible only upon your own renunciation application through a consulate; the act at the Registro Civil does not affect it.
Yes: marriage to a Spanish citizen — 1 year of residence, refugee status — 5 years. For all other Russian citizens the general period applies.
How the whole journey looks — from the first card to the passport — is shown in the article on the path from residence to naturalization, and all current thresholds and timelines are gathered in the 2026 figures summary.
