Fastest EU Citizenship for Founders in 2026: France's 5 Years vs Portugal and Spain's 10

If you are choosing a founder visa in 2026 partly for the passport at the end of it, the three countries Relovisa files in no longer line up the way most guides still claim. France is now the only one of the three with a sub-decade path to citizenship: 5 years of residence, or just 2 if you hold a French higher-education diploma. Portugal raised its standard naturalisation wait to 10 years (7 for nationals of countries where Portuguese is an official language and for EU citizens) with Lei Orgânica n.º 1/2026, in force 19 May 2026, and Spain has long required 10 years for anyone outside its Ibero-American fast track. So the headline is simple, France 5, Portugal and Spain 10, but the founder-relevant detail is in the fine print: France's 5-year edge only counts if you actually live there and clear a tougher B2-plus-civic-exam bar introduced on 1 January 2026; Spain still makes most applicants renounce their current passport; and Portugal and France both let you keep dual nationality. This is general information, not legal advice: confirm your own timeline with a qualified lawyer in the country you choose.

The 2026 comparison at a glance

The table below is the spine of the decision. Read the "reduced route" row carefully: each country's shortcut applies to a different, narrow group, and for most founders moving from outside the EU and Latin America, the standard column is the one that governs.

Two things fall out of this immediately. First, the gap between France and the Iberian pair doubled in 2026: it used to be 5 years everywhere bar Spain's standard route; now it is 5 versus 10. Second, the number of years is not the whole cost: Spain's renunciation requirement and France's raised exams are real frictions that a bare "5 vs 10" comparison hides.

France: 5 years, the real edge, and its real conditions

French naturalisation par décret requires five years of habitual residence in France (Article 21-17 of the Code civil). That drops to two years if you have earned a diploma from a French higher-education institution after at least two years of study: a genuinely useful shortcut for founder-operators who did, or could do, a French master's. France also permits dual citizenship, so you are not asked to surrender your existing passport.

That is the upside, and after Portugal's reform it is a meaningful one: France is the fastest route to an EU passport among the three programmes we file. But two 2026 conditions decide whether the five years actually deliver.

First, the language and civic bar rose on 1 January 2026. Under Décret n.º 2025-648 du 15 juillet 2025 (with the implementing arrêté of 10 October 2025), naturalisation now requires French at level B2 in both speaking and writing, one full CEFR level above the old B1 standard, plus a civic exam: a 40-question multiple-choice test on French history, culture and society, passed at 80% (32 of 40). This is not a formality you clear at the counter; it is a test you prepare for.

Second, and more strategically: naturalisation rests on assimilation and habitual residence, France being the genuine centre of your material and family interests. This sits in direct tension with a common founder structure, holding a French residence permit while keeping tax residency elsewhere. You can do the latter for the permit (we explain how in France residence permit without French tax residency), but you cannot run that structure for five years and expect a clean naturalisation file at the end. If citizenship is the goal, France has to be where you actually live. Treat the permit play and the passport play as two different decisions.

For founders, the on-ramp is the Talent - porteur de projet permit (the French Tech Visa for founders), valid up to four years and renewable, which we cover end-to-end in the French Tech Visa for Founders 2026 guide. It is the residence base from which the five-year clock runs.

Weighing France for the citizenship horizon specifically? The five-year path is the strongest on the continent for founders right now, but only if the residence is real. Talk to us about the France Talent route before you optimise yourself out of it.

Portugal: 10 years now (7 on the language/EU track), and the clock starts at the card

Portugal used to be the EU's headline "5 years to a passport" story for founders. That ended on 19 May 2026, when Lei Orgânica n.º 1/2026, de 18 de maio (Diário da República n.º 95/2026, Série I) entered into force and raised standard naturalisation to 10 years, with 7 years for nationals of countries where Portuguese is an official language and for citizens of EU member states (article 6(1)(b) of the amended Lei 37/81). For a founder relocating from the US, UK, Russia or most of the world, the figure that applies is 10.

First, get the date right. The law was published in Diário da República n.º 95/2026, Série I, on 18 May 2026 and entered into force the following day. You will still see "1 April 2026" and "signed 3 May 2025" circulating in guides and forum threads: those refer to earlier stages of the legislative process, not the in-force date. Use 19 May 2026.

The clock starts at the card, not at the consulate

The new regime counts your residence from the issuance of your first residence permit: the date AIMA actually issued the card. Not the date you submitted your visa file at the consulate, not the date your business plan or income was approved, and not the date you later sit down to apply for nationality.

That has a practical sting. AIMA processing has run months behind its statutory targets through 2026, and every month between your consular submission and your card issuance is a month that does not count. The gap between "I started this process" and "my clock started" can be most of a year, which is why filing cleanly and getting the card issued without avoidable back-and-forth is worth more here than picking a clever route.

Whether residence time you accrued before 19 May 2026 still counts toward the new ten-year total remains unsettled. Article 4 of the law set a 90-day deadline (16 August 2026) for the updated Regulamento da Nacionalidade; that deadline passed with nothing published in the Diário da República, and the consolidated text there still stops one amendment short of Lei Orgânica n.º 1/2026. The deadline is a prazo ordenador, a target rather than a mandatory one, so missing it does not suspend or annul the 10/7-year rule itself: the new timeline is in force regardless. What it does mean is that the procedural edge cases, including the pre-reform-time question, are still open. Do not bank on a favourable answer in either direction; put your own start date to a Portuguese lawyer.

Per route: D2, D7, D8 and the Golden Visa are identical

This is the part founders expect to differ by permit, and it does not. The clock-start rule and the number of years are the same across every Portuguese residence route. That sameness is the information.

If you are weighing the Portuguese permits against each other on speed to a passport, the citizenship clock is not the tie-breaker: they are identical on it. The choice comes down to who fits which permit and how you intend to live and earn, which we cover in D2 vs D7 vs D8 for 2026 and, for the freelancer-tax angle, D3 vs D8.

The Golden Visa deserves one line of its own, because the claim that it kept a shorter path is still widely repeated. It did not: Autorização de Residência para Investimento moved to 10 years (7 on the language/EU track) like everyone else. Its one genuine structural advantage is unrelated to the number of years, and it is the minimal physical-presence requirement that lets the naturalisation clock run while you live outside Portugal. A D2, D7 or D8 holder, by contrast, is expected to actually reside there.

The transitional rule nearly every guide gets wrong

A widespread claim, especially in third-party and Russian-language guides, is some version of "any residence-permit holder from before the cutoff keeps the shorter path." That is false, and it is the single most expensive misreading of this reform.

The transitional provision protects exactly one group: nationality applications already submitted to the IRN (Instituto dos Registos e do Notariado) on or before 18 May 2026, which continue to be decided under the prior Lei 37/81 regime. There is no provision protecting people who merely held a residence permit but had not yet filed for citizenship. So the test is not "did I have a permit before 19 May 2026?" but "had I already lodged my nationality application by 18 May 2026?" If you have not filed, then even a D2, D7, D8 or Golden Visa card issued in 2023, 2024 or early 2025 puts you on the ten-year (or seven-year) clock.

The litigation picture is easy to garble, so here is the honest version. The Constitutional Court did rule on the reform in December 2025 (Acórdão n.º 1133/2025), but that was a preventive (a priori) review requested by 50 members of parliament, not a case brought by investors, and it upheld the 10-year timeline while striking four of seven contested provisions for an inadequate transitional regime, which is exactly why Parliament redrafted the text that became Lei Orgânica n.º 1/2026. The years themselves therefore survived constitutional review. What remains genuinely open is the post-enactment wave: collective actions being prepared by Golden Visa investors and an Ombudsman (Provedor de Justiça) complaint, both arguing legitimate expectations and the AIMA backlog. If you hold an ARI permit specifically for the citizenship horizon, that ongoing litigation, not the settled December ruling, is what to track with counsel.

What did not change: permanent residence at 5 years, and Portugal's acceptance of dual citizenship. So Portugal is now a ten-year passport play but a five-year settle-permanently play, and you keep your original nationality at the end. Keep those three clocks separate, because conflating them is the commonest reader error: PR eligibility (5 years), naturalisation (10, or 7 on the language/EU track), and the narrow grandfather (pre-filed nationality applications only). The language and civics side has its own open question, which we track in Portugal's citizenship civic test.

Spain: 10 years, continuous residence, and you give up your old passport

Spain has always required 10 years of legal and continuous residence for standard naturalisation. Its fast track, 2 years, is real but narrow: it covers nationals of Ibero-American countries, Andorra, the Philippines, Equatorial Guinea, Portugal, and Sephardic Jews. A founder arriving on the Spain Startup visa or the digital nomad visa from outside that list is on the full ten years.

Two features make Spain's ten heavier than Portugal's ten for many founders:

• Renunciation. Spain generally requires you to renounce your prior nationality on naturalising. The dual-nationality exemption is narrower than the fast-track list: only natural-born nationals of Ibero-American countries, Andorra, the Philippines, Equatorial Guinea and Portugal keep both passports (by treaty). Sephardic Jews get the 2-year residence track but are not on that treaty list, so they must, in principle, still renounce. If keeping your current passport matters, and for most founders it does, Spain's citizenship is a different proposition from France's or Portugal's dual-friendly one.
• Continuity. The ten years must be continuous; long absences can break the clock, which is a live risk for founders who travel heavily or split time across markets. You also sit the CCSE civics test and, unless exempt, the DELE A2 Spanish exam.

As in the other two countries, long-term residence at 5 years is a separate, earlier milestone, and for founders whose Spanish interest is primarily tax (the Beckham regime) rather than a passport, that question is best kept apart from citizenship entirely; we compare the tax angle in IFICI vs Beckham Law.

So which visa should a founder pick in 2026?

Citizenship horizon should inform the choice, not dictate it, but here is the honest read:

• Want the fastest EU passport and willing to truly live in France? France Talent is the clear winner: 5 years (2 with a French degree), dual nationality kept. Budget for B2 French and the civic exam, and for genuinely centring your life there.
• Want flexibility, dual nationality, and a strong 5-year settlement (not citizenship) milestone? Portugal. The passport is now 10 years out, but PR at 5 and dual citizenship remain, and the entry permits (D2/D3/D8) are founder-friendly.
• Optimising for the business and tax setup more than the passport? Spain can still be right, the Startup visa and Beckham regime are excellent, but go in clear-eyed that citizenship is 10 years away and costs you your current nationality unless you are Ibero-American.

For most founders choosing today with a passport in mind, the decision has genuinely shifted toward France since Portugal's reform.

FAQ

Which EU country gives founders the fastest path to citizenship in 2026? France: 5 years of habitual residence, or 2 years with a French higher-education diploma. Portugal and Spain are both 10 years for the typical non-EU, non-Ibero-American founder.

Did Portugal really raise citizenship from 5 to 10 years? Yes, Lei Orgânica n.º 1/2026, in force 19 May 2026: 10 years standard, 7 for nationals of Portuguese-official-language countries and EU citizens, clock from permit issuance. Only IRN applications filed by 18 May 2026 keep the old 5-year rule.

Does Spain make you give up your current passport to naturalise? For most applicants, yes: Spain generally requires renunciation. The dual-nationality exemption (by treaty) covers Ibero-American countries, Andorra, the Philippines, Equatorial Guinea and Portugal; Sephardic Jews get the 2-year residence track but must in principle still renounce. France and Portugal both allow dual citizenship.

Does the France 5-year clock work if I don't pay tax in France? Not reliably. Naturalisation needs habitual residence and assimilation, France as the centre of your interests, which conflicts with structuring to avoid French tax residency. The permit and the passport are two different goals.

Is the France citizenship language requirement really B2 now? Yes, since 1 January 2026 (Décret n.º 2025-648 of 15 July 2025): B2 oral and written, plus a 40-question civic exam passed at 80%.

When does each country's citizenship clock start counting? France: habitual residence. Portugal: AIMA's issuance of your first residence permit. Spain: legal and continuous residence. Permanent residence at 5 years is a separate, earlier milestone in all three.
