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 from 5 to 10 years (7 for CPLP and EU nationals) 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.

	France (Talent)	Portugal (D2 / D3 / D8)	Spain (Startup / DNV)
Standard naturalisation	5 years	10 years	10 years
Reduced route	2 years — French higher-ed diploma (≥2 years’ study)	7 years — CPLP or EU nationals	2 years — Ibero-American, Andorra, Philippines, Eq. Guinea, Portugal, Sephardic Jews
When the clock starts	Habitual residence in France	Issuance of your first residence permit	Legal and continuous residence
Dual citizenship?	Allowed	Allowed	Generally no — must renounce (except Ibero-Americans, Andorra, Philippines, Eq. Guinea, Portugal)
Language + civic test	B2 (oral + written) + civic exam, since 1 Jan 2026	A2 + new history/civic test (regulation pending)	DELE A2 + CCSE (nationals of Spanish-speaking countries exempt from DELE)
Permanent residence milestone	Carte de résident at 5 years	PR at 5 years (unchanged by the reform)	Long-term residence at 5 years

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 for CPLP and EU) — 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 from 5 to 10 years, with 7 years for nationals of CPLP (Portuguese-speaking) countries and EU member states. For a founder relocating from the US, UK, Russia or most of the world, the figure that applies is 10.

Three mechanics matter, and we unpack them fully in the dedicated Portugal 10-year citizenship clock, per route:

• The clock starts at residence-permit issuance — the day AIMA issues your card, not the day you filed at the consulate. With AIMA running months behind, the gap can be the better part of a year.
• The route does not change the number. D2, D7 and D8 are all on the same 10/7-year clock; the permit you pick is a question of who qualifies, not of speed to citizenship (see D2 vs D7 vs D8 for 2026).
• Almost nobody is grandfathered. Only citizenship applications already lodged with the IRN on or before 18 May 2026 keep the old 5-year regime. Holding a permit from 2023–2025 does not. Whether residence time accrued before 19 May 2026 counts toward the new 10 years is, as of June 2026, unsettled — a 90-day implementing regulation (Article 4 of the law) was still pending and the transition regime is being challenged politically and in petitions.

What did not change: permanent residence at 5 years, and Portugal’s acceptance of dual citizenship. So Portugal is now a 10-year passport play, but a 5-year settle-permanently play — and you keep your original nationality at the end.

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. If the five-year French path fits your life, the on-ramp is the Talent founder permit — start the France Talent conversation here, and we will tell you honestly whether your residence plan supports a citizenship file or just a permit.

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 CPLP and EU nationals, 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.
