From Golden Visa to Citizenship: Portugal, Greece, Spain, and Malta Pathways Compared

Golden visa programmes — residency-by-investment schemes operating across Europe — are frequently marketed as pathways to EU citizenship. The reality is more nuanced: a golden visa confers residency, not citizenship, and converting that residency into a passport requires meeting the naturalisation conditions of the host country, which vary significantly in their demands on the applicant.

For HNW investors who want EU citizenship as the ultimate objective, understanding the full journey from initial investment to passport — the time, the presence requirements, the language tests, and the discretionary elements — is essential to making the right programme choice.

This guide compares the naturalisation pathways available through Portugal, Greece, Spain, and Malta, the four principal European investment migration routes to EU citizenship.

Naturalisation rules in all European countries are subject to change by legislation, policy, and administrative practice. The requirements described here reflect the position as of June 2026 but may be altered. Always verify current requirements with a qualified immigration lawyer in the relevant country before making any planning decision.

Portugal: The Pathway (Residency Requirement Extended in 2026)

Portugal's golden visa programme, in operation since 2012, has been the most popular investment migration route to EU citizenship globally. Despite significant changes in 2022–2023 — most notably the removal of Lisbon, Porto, and coastal areas from the eligible real estate investment zones — the programme continues to operate with investment in low-density inland areas, approved real estate investment funds, and certain qualifying business investments.

Important 2026 change: Portugal's revised Nationality Law (approved April 2026 and in force from May 2026) extended the qualifying residence period for naturalisation from five years to ten years for nationals of most countries (and to seven years for EU and CPLP/Portuguese-speaking nationals). The widely-cited "five-year path to a Portuguese passport" no longer reflects the standard rule for new non-EU applicants. Transitional arrangements for existing golden visa holders and pending applications were the subject of debate as the law passed; investors who began the process under the old regime should take specific Portuguese legal advice on exactly which residence period applies to them.

The Investment

The fund investment route — placing €500,000 into a qualifying Portuguese investment fund — has become the most frequently used route for international investors following the property zone restrictions. Direct real estate investment remains available in qualifying areas.

The Residency Period

Golden visa holders must maintain their residency permit by meeting the minimum physical presence requirements — currently seven days in the first year and 14 days in each subsequent two-year renewal period. Permanent residency remains available after five continuous years of legal residence (with a clean criminal record). Citizenship by naturalisation, however, now requires ten years of legal residence for most non-EU applicants under the 2026 Nationality Law (seven years for EU/CPLP nationals), subject to any transitional treatment of applicants already in the pipeline.

Physical Presence Requirements

Portugal's minimum physical presence requirements for golden visa holders are significantly lower than for standard visa categories — seven days in the first year, 14 days per two-year renewal period. This makes Portugal attractive for investors who cannot or do not wish to relocate to Portugal full-time.

However, for naturalisation purposes, the applicant must demonstrate a genuine connection to Portugal, which AIMA and the Ministry of Justice assess more broadly than simply counting nights. In practice, investors who have spent the absolute minimum 14 days per renewal period may find their naturalisation applications subject to more scrutiny than those with documented longer stays, Portuguese financial activity, or demonstrable ties.

Language Requirement

Naturalisation in Portugal requires Portuguese language proficiency to A2 level (elementary) as assessed by an approved test (typically the CIPLE exam, certified by CAPLE at the University of Lisbon). A2 represents the ability to understand and use familiar everyday expressions and basic phrases. This is achievable with dedicated study — typically 80–150 hours of instruction for most adult learners — but it is a genuine requirement, not a formality. (Nationals of Portuguese-speaking countries, and those educated in Portuguese, are generally exempt.)

Language tuition can begin from the date the golden visa is granted. Many investors begin studying from day one, giving ample time to reach A2 standard. Online tuition and intensive courses are widely available.

Criminal Record and Good Conduct

A clean criminal record — from Portugal and from every country the applicant has resided in — is required. Evidence of integration into Portuguese society (bank account, tax registration, property ownership, voluntary engagement, professional activity) supports the application.

Renunciation Requirements

Portugal does not require applicants to renounce their existing citizenship(s) on naturalisation. Portugal permits dual and multiple nationality. This is one of Portugal's most significant advantages — EU citizenship through Portugal involves no trade-off with existing status.

Timeline (Realistic)

• Year 0: Golden visa investment and initial application (3–6 months to approval)
• Years 1–10: Minimum physical presence maintained; periodic renewals; language study (permanent residency available from year 5; naturalisation now from year 10 for most non-EU applicants under the 2026 law)
• After the qualifying residence period: Naturalisation application — typically 12–24 months from submission to passport in hand (AIMA processing times have been slow; improvements are ongoing)

Total realistic timeline from investment decision to EU passport: around 11–12 years for new non-EU applicants under the 2026 Nationality Law (previously 6–8 years; investors already in the pipeline should confirm whether transitional provisions preserve a shorter period for them).

Greece: The Seven-Year Pathway

Greece's golden visa — the entry investment threshold has been raised progressively: from €250,000 to €400,000 in certain areas, and to €800,000 in Athens, Thessaloniki, Mykonos, and Santorini — is a residency permit granted for five years and renewable indefinitely provided the investment is maintained.

Physical Presence Requirements for Residency

Greece's golden visa has no minimum physical presence requirement for renewal. This makes Greece an extremely flexible option for investors who want the EU residency status without being physically present in Greece. The residency card can be renewed indefinitely.

The Naturalisation Threshold

Greek citizenship by naturalisation requires seven years of legal residence in Greece. This is measured from the date of the original residency permit, not from the date of the most recent renewal. For golden visa holders, the seven-year clock starts from the initial golden visa grant.

Physical Presence Requirements for Naturalisation

Here is where Greece's flexibility ends: Greek naturalisation requires evidence of genuine residency and ties to Greece over the seven-year period. A Greek government official may interview the applicant; evidence of engagement with Greek society (Greek bank account, tax filings, healthcare usage, community involvement) is assessed.

Unlike Portugal, where the minimum physical presence threshold for the visa itself is formally specified, Greece's assessment is more holistic but no less genuine. Investors who spent the minimum number of days in Greece (which may be zero) and then present a naturalisation application after seven years will face scrutiny on whether their residence was genuine.

Language Requirement

Greek language proficiency to B1 level is required for naturalisation. Greek is a significantly more demanding language to learn than Portuguese for most European and Asian investors. The assessment includes oral and written components. This is the most challenging aspect of the Greek pathway for many investors.

Renunciation Requirements

Greece, as an EU member state, permits dual nationality in most circumstances. Applicants are not required to renounce other citizenships to naturalise as Greek citizens in the standard case.

Naturalisation Discretion

Greek citizenship is granted by Presidential Decree, and the process has a discretionary element. An applicant who meets all formal criteria is not automatically entitled to citizenship — the competent authority retains discretion. In practice, well-documented applications with genuine ties to Greece are approved; applications that appear to treat Greece merely as a mechanism for obtaining an EU passport with minimum engagement face a harder path.

Spain: The Ten-Year Pathway

Spain closed its golden visa programme to new applicants on 3 April 2025, so the property-investment route (formerly €500,000 for real estate, with lower thresholds for certain other investment types) is no longer open. The discussion below therefore applies to investors who obtained Spanish residency before the closure, or who hold Spanish residency through another route (such as the Non-Lucrative Visa). For those already on the Spanish path, naturalisation remains the most demanding in this comparison.

The Naturalisation Requirement

Spanish citizenship by naturalization generally requires ten years of legal residence. This is the standard period — there are reductions for certain categories (nationals of Ibero-American countries, Philippines, Equatorial Guinea, and Portugal: two years; Sephardic Jews with documented Spanish connection: two years; those married to a Spaniard: one year) but for most HNW international investors, the standard ten-year period applies.

Physical Presence Requirements

Spain's golden visa renewal requires maintaining the property investment but no minimum physical presence. However, for naturalisation, genuine residence and ties must be demonstrated. Additionally, Spain applies a more stringent standard for naturalisation presence than Portugal — tax residence in Spain and substantive life connection are expected.

Language and Integration Requirements

Spanish language to A2 level (for the DELE language exam) and a knowledge test (CCSE — Constitutional and Sociocultural Knowledge of Spain) are required. Spanish is a highly accessible language for most investors; the A2 level is a modest requirement relative to Greece's B1 Greek requirement.

Timeline Reality

Ten years is a very long horizon for investors whose primary objective is EU citizenship. Spain's naturalisation pathway is best suited to investors who genuinely want to live in Spain long-term and for whom the golden visa is a route to legalising a lifestyle choice rather than a citizenship strategy.

Renunciation

Spain generally requires renunciation of other citizenships for most naturalisees — this is a critical distinction. Spain does not permit dual nationality for most foreign nationals who naturalise (exceptions apply for nationals of certain countries with bilateral treaties). An investor who naturalises as Spanish will typically be required to formally renounce their other citizenship(s).

This makes Spain's pathway significantly less attractive for investment migration purposes compared to Portugal and Greece, where no renunciation is required.

Malta: The MEIN 3-Year Pathway (With Residency)

Malta's Citizenship by Naturalisation for Exceptional Services by Direct Investment (MEIN) is technically a naturalisation programme requiring prior residency — but it is structured and priced as a citizenship acquisition, not a conventional golden visa.

The key distinction: the residency required by Malta's MEIN is 12 months (with a larger financial contribution: €750,000) or 36 months (with the standard contribution: €600,000), plus property (purchase or rental) and charitable donation.

Why Malta Is Different

Malta's MEIN is not a golden visa programme that leads to citizenship. It is a citizenship programme that requires a pre-residency period as a procedural condition. The government contribution is specifically the price of citizenship — it is non-refundable.

The Malta pathway takes 12–36 months to citizenship, compared to five to ten years for Portugal/Greece/Spain. This premium timeline is precisely what the premium price buys.

Language, Integration, Physical Presence

Malta does not impose a formal language test for MEIN applicants. The residency requirement is genuine — applicants must demonstrably be resident in Malta — but the integration standard is lower than for conventional naturalisations. Malta is Anglophone, which makes residency accessible for most investors.

Renunciation

Malta does not require renunciation. Maltese citizenship by MEIN is fully compatible with retaining existing citizenships.
