Dual citizenship of Russia and Spain: is it possible in 2026

Updated: 22 August 2026 · Verified by the EuroGarant team against official sources

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 and second citizenship: the difference that decides everything

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.

What Spain requires at naturalization

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.

What happens to the Russian passport

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.

Residence periods before the naturalization application

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 categoryRequired residenceRenunciation required?
Citizens of Russia and most third countries10 yearsYes, a declaration at the Registro Civil
Spouse of a Spanish citizen1 yearYes
Recognized refugees5 yearsYes
Ibero-America, Portugal, Andorra, the Philippines, Eq. Guinea2 yearsNo — 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.

A Russian citizen's route: card → permanent residence → passport

  1. First residence permit. DNV, NLV, studies or family reunification — choosing the right ground is covered in the overview of options available to Russians.
  2. Renewals without gaps. Any gap between cards resets the continuity of your residence record.
  3. Long-term residence. The right opens after a minimum period of residence: 5 years — the conditions are gathered on the page on permanent residence in Spain.
  4. Exams. DELE A2 (language) and CCSE (constitution and society) — taken before filing the application.
  5. Application and oath. Then comes the wait for a decision and the act at the Registro Civil.

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.

Taxes: passport and residency are different things

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.

Common mistakes

Quick answers

What counts as your second country in the eyes of a consulate?

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.

Will the Russian passport be taken away after the oath?

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.

Is there a shorter path than the general period?

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.
