How to Get a Second Passport in 2026: Every Legal Route Explained

The quickest legal way to get a second passport in 2026 is citizenship by investment: five Caribbean states grant citizenship for a government contribution from USD 200,000 (Dominica) to USD 250,000 (St Kitts and Nevis), usually within months rather than years. Without investment, the main routes are descent, marriage or naturalisation, which typically take several years of residence.

What is a second passport, and is it legal to hold one?

A second passport is the travel document of a second citizenship, held lawfully alongside your first, and it is legal whenever both countries permit dual nationality. The passport is only the proof: the asset is the citizenship behind it, which gives you the right to live in that country, to pass nationality to your children and to consular protection abroad.

Legality depends on two laws, not one. The country granting the new citizenship must allow you to keep your existing nationality (all the investment programmes in this guide do), and your current country must allow you to acquire another one. Germany, for example, has permitted dual nationality without special approval since its nationality reform of June 2024, while India and China do not recognise dual nationality for their citizens. Before choosing any route, confirm the position in your home country, because that rule decides whether a second passport adds options or replaces your first.

People pursue a second citizenship for practical reasons: easier travel, a residence option for the family, access to a wider banking and business network, and the reassurance of a lawful alternative if circumstances change at home. Mirabello Consultancy calls this disciplined planning a Plan B, and it works best when it is arranged calmly, years before it is needed.

What are the legal routes to a second passport?

The legal routes to a second passport are citizenship by descent, by marriage, by naturalisation after residence, by investment, by residence by investment followed by naturalisation, and by exceptional grant. Each route is defined in the granting country's nationality law, and the right one depends on your family history, your timeline and your budget.

For most internationally active families, the realistic choice is between investment, which is fast and does not require relocation, and residence-based naturalisation, which is slower but often leads to a passport inside a larger bloc such as the European Union. Descent and marriage are excellent where they exist, but they cannot be chosen: you either have the family link or you do not.

How does citizenship by descent work?

Citizenship by descent recognises that you already hold a nationality, or are entitled to it, because a parent or grandparent was a citizen. Citizenship by descent is usually the least expensive route to a second passport, but it depends entirely on documents: birth, marriage and naturalisation records that prove an unbroken line to the ancestor.

Rules vary widely. Some countries recognise only children of citizens, others extend to grandchildren, and several European states tightened their generation limits in recent years, so a claim that was valid a decade ago may need fresh review. Caribbean states also offer descent routes: Mirabello Consultancy advises on St Kitts and Nevis citizenship by descent and Grenada citizenship by descent, where the starting point is always the ancestor's civil records. If you suspect a family link, it is worth investigating before considering investment, because a valid descent claim can save a significant sum.

Can you get a second passport through marriage?

Marriage to a citizen can lead to a second passport, but almost no country grants citizenship automatically on marriage. Spouses normally apply after a qualifying period of marriage, and many countries also require a period of residence, language knowledge and evidence that the relationship is genuine.

Within the Caribbean, Mirabello Consultancy handles St Kitts and Nevis citizenship by marriage, Grenada citizenship by marriage and Antigua and Barbuda citizenship by marriage. A practical note for families using investment instead: every Caribbean and Pacific programme in this guide lets a spouse and dependent children qualify in the same application, so a family does not need a separate marriage route to secure citizenship together.

How long does citizenship by naturalisation take?

Citizenship by naturalisation typically takes 5-10 years of lawful, actual residence, followed by language, integration and good-character requirements. Naturalisation is the most widely available route to a second passport, but it requires you to genuinely live in the country, which makes it a relocation decision rather than a planning tool.

Two European examples show how demanding the timelines have become. Portugal's Lei Orgânica 1/2026 raised the naturalisation period to 10 years of legal residence for most nationalities, or 7 years for EU and CPLP nationals, and added knowledge of Portuguese language and culture. Greece requires 7 years of actual residence, a language examination and demonstrated integration; holding a residence permit while living elsewhere does not count. Anyone planning a European passport through residence should therefore budget a decade, not a few years.

What is citizenship by investment and which countries offer it in 2026?

Citizenship by investment (CBI) is a legal route in which a country grants full citizenship to an applicant who passes enhanced due diligence and makes an approved economic contribution or investment. In 2026, CBI programmes operate in five Caribbean states, Vanuatu, Türkiye and Nauru, and in Argentina, whose programme launched on 2 October 2026.

CBI is not a purchase of a passport. Each application is assessed by a government unit, background checks are run on every adult applicant, and citizenship is granted under the country's own nationality law, with the same rights as any other citizen. Short definitions of each programme follow.

What is Antigua and Barbuda citizenship by investment? Antigua and Barbuda grants citizenship for a National Development Fund contribution from USD 230,000, which covers a family of up to four, with an approved real estate route from USD 300,000. Citizens must spend 5 days in the country within the first 5 years. See our Antigua and Barbuda programme page.

What is St Kitts and Nevis citizenship by investment? St Kitts and Nevis, the oldest programme, starts from a USD 250,000 Sustainable Island State Contribution covering up to four family members, and its real estate route starts from USD 325,000. National biometric enrolment launched on 14 April 2026. Details are on our St Kitts and Nevis page.

What is Dominica citizenship by investment? Dominica grants citizenship for an Economic Diversification Fund contribution from USD 200,000 for a single applicant, with a family of four from USD 250,000, and sets no residence requirement before or after citizenship. Read more on the Dominica programme page.

What is Grenada citizenship by investment? Grenada grants citizenship for a National Transformation Fund contribution from USD 235,000 for a single applicant or a family of up to four, with approved tourism real estate from USD 270,000. Grenada is the only one of the five Caribbean programmes whose citizens can apply for the E-2 treaty investor visa of the United States. See the Grenada programme page.

What is St Lucia citizenship by investment? St Lucia grants citizenship for a National Economic Fund contribution from USD 240,000 for an applicant with up to three dependants, with a government bond route from USD 300,000. Our St Lucia page sets out every option.

What is Vanuatu citizenship by investment? Vanuatu grants citizenship for a Development Support Program contribution from USD 130,000 for a single applicant and is typically the fastest of the established programmes. The Vanuatu passport does not currently give visa-free access to the Schengen Area. See the Vanuatu programme page.

What is Nauru citizenship by investment? Nauru's Economic and Climate Resilience Citizenship Programme accepts a contribution of USD 90,000 for a principal applicant until 31 December 2026, after which the standard USD 115,000 applies; government fees are payable on top. Visit our Nauru programme page.

What is Türkiye citizenship by investment? Türkiye grants citizenship to investors who buy real estate from USD 400,000, held for at least three years, or who place USD 500,000 in a qualifying bank deposit or fixed capital investment. See the Türkiye programme page.

What is Argentina citizenship by investment? Argentina's programme, launched by the Ministry of Economy on 2 October 2026, grants citizenship for a non-refundable National Treasury contribution of USD 350,000 or a USD 800,000 programme government bond, with applications opening in the fourth quarter of 2026. No official end-to-end processing time is published; Decreto 524/2025 requires the National Directorate of Migration to decide within 30 days of receiving the report of the Agency for Citizenship by Investment Programmes. Our Argentina page and our guide to Argentina's citizenship by investment launch cover the details.

How much does a second passport cost in 2026?

A second passport through investment costs from USD 90,000 in Nauru (a limited-time price until 31 December 2026) and from USD 200,000 in the Caribbean, before government fees and due diligence. The headline contribution matters less than the total for your family, because programmes price spouses, children and adult dependants differently.

On top of the contribution, budget for government application, due diligence and passport fees, which vary by programme and by the age of each dependant, plus professional fees. Real estate routes cost more upfront but leave you with an asset that can be resold after the statutory holding period. For a side-by-side view of price and speed, read our guide to the most cost-effective and fastest second passports in 2026.

What is the fastest way to get a second passport?

The fastest way to get a second passport is citizenship by investment, and Vanuatu is typically the quickest programme. Among published government timelines, Nauru states three to four months from submission to approval, and St Kitts and Nevis decides within 120 to 180 days of acknowledgement. Every timeline assumes a complete file, because missing or inconsistent documents cause most delays.

Speed should not be the only criterion. Vanuatu is the fastest, but its passport carries fewer visa-free destinations and no Schengen visa-free access. Many families therefore accept a few extra weeks for a Caribbean passport with broader mobility. Due diligence is the step no adviser can shorten: every adult applicant is screened, and a clean, documented source of funds is what keeps a file moving.

Can a golden visa lead to a second passport?

A golden visa can lead to a second passport, but only indirectly: it grants residence, and citizenship follows only if you later meet the country's full naturalisation rules. In the European Union that now means 7-10 years of legal residence plus language and integration requirements, so a golden visa is a long-term path, not a quick passport.

What is the Portugal Golden Visa? The Portugal Golden Visa is a residence permit available from EUR 250,000 through arts and cultural heritage support, or EUR 500,000 through qualifying funds. Holders spend 7 days in Portugal in the first year, but naturalisation requires 10 years of legal residence for most nationalities under the 2026 reform. See the Portugal Golden Residence Permit page.

What is the Greece Golden Visa? The Greece Golden Visa is a residence permit linked to real estate or startup investment, with thresholds set by zone and property type. The Greece Golden Visa does not lead to citizenship on its own: Greek naturalisation requires 7 years of actual residence in Greece, a language examination and integration. See the Greece Golden Visa page.

European golden visas are designed for non-EU nationals; EU, EEA and Swiss citizens already have free movement and are not the audience for them. For a structured comparison of the two strategies, read our comparison of all five Caribbean programmes and the golden visa hub.

Do you have to live in the country to keep a second passport?

Most investment-based second passports require little or no residence: Grenada, Dominica and St Lucia set no presence requirement, and Antigua and Barbuda requires 5 days within the first 5 years. Naturalisation routes are the opposite, because years of actual residence are the qualifying condition itself.

The regional picture is changing, but slowly. The Eastern Caribbean Citizenship by Investment Regulatory Authority (ECCIRA) was created by an agreement signed in September 2025 and established in December 2025, with an office in Grenada. ECCIRA is not yet operating; the Eastern Caribbean Central Bank expects it to begin operating later in 2026, and no start date has been announced. Proposals discussed for the region, including 30 days' presence in the first 5 years, an initial 5-year passport and mandatory regional biometrics, are not in force. National rules already in place include St Kitts and Nevis biometric enrolment, launched on 14 April 2026, with existing CBI citizens asked to enrol by 31 July 2027. Our country-by-country guide to the Caribbean rules in force and our ECCIRA explainer track every change.

Which second passport gives the best visa-free access?

Among investment programmes, the Argentine passport offers the widest access, with 170 visa-free destinations. In the Caribbean, St Kitts and Nevis leads with 157, followed by Antigua and Barbuda with 154, Grenada with 147, Dominica with 145 and St Lucia with 144.

Raw counts hide the destinations that matter most to you. All five Caribbean passports currently give visa-free short stays in the Schengen Area. For the United Kingdom, Antigua and Barbuda, St Kitts and Nevis and Grenada citizens visit without a visa using an Electronic Travel Authorisation, while Dominica citizens have needed a visa since 19 July 2023 and St Lucia citizens since 5 March 2026. Vanuatu citizens have needed a UK visa since 19 July 2023, and Vanuatu has no Schengen visa-free access. If one destination drives your decision, check it first, then compare cost.

What does the application process look like, step by step?

A citizenship by investment application follows five steps: eligibility and suitability review, document preparation, submission through a licensed agent, government due diligence, and approval followed by the investment and oath or passport issue. Most of the elapsed time is due diligence, so the quality of the file drives the timeline.

1. Strategic assessment: your nationality, family, travel needs and tax position decide which route and programme fit.
2. Documents: passports, birth and marriage certificates, police certificates, medical reports and a full source-of-funds file, with certified translations where needed.
3. Submission: Caribbean and Pacific programmes accept applications only through government-licensed agents.
4. Due diligence: government units commission background checks on every adult, and some programmes hold interviews, often remotely.
5. Approval and investment: in the Caribbean and Pacific contribution programmes, you make the contribution or complete the investment only after approval in principle (Türkiye is the exception: the qualifying investment comes first), then receive the certificate of citizenship and passports.

Does a second passport change your tax position?

A second passport does not by itself change your tax position, because most countries tax on residence, not citizenship. Your obligations follow where you live, where your income arises and where you are tax resident, so citizenship planning and tax planning must be advised together, with qualified tax counsel in each relevant country.

Banks and tax authorities exchange account information under the OECD Common Reporting Standard, and financial institutions ask for your tax residence, not your passport. The OECD also publishes a list of residence and citizenship by investment schemes it considers potentially high-risk for reporting purposes; in practice this means a bank may ask for additional evidence of where you are tax resident. Anyone considering emigration-related tax events, such as an exit tax, should take specialist advice before any change of residence.

Which route suits your nationality and situation?

The right route to a second passport depends on your current nationality, where you live, your family and what you want the passport to do. Business owners in the Gulf, for example, often prioritise speed and family inclusion, while European families planning a relocation may prefer residence and eventual naturalisation.

• Gulf and Middle East residents: many prefer Caribbean programmes that cover a family of four in one contribution and require no relocation. See our Caribbean comparison.
• UK nationals: British citizens already travel widely, so the value of a second citizenship lies in residence rights and family planning; the UK visit rules above matter for family members who are not British.
• German nationals: since the June 2024 reform, Germans can acquire another citizenship without losing German nationality, which opens every route in this guide.
• Families who want to live abroad: residence programmes such as the UAE Golden Visa provide a home base, while a CBI passport provides travel and a fallback citizenship.

How do you choose a trustworthy second passport adviser?

A trustworthy second passport adviser is licensed as an authorised agent where programmes require it, transparent about every government fee, honest about eligibility and never promises approval. Professional memberships, anti-money-laundering certification and a clear explanation of due diligence are the signals that separate advisers from sales intermediaries.

Ask any adviser how fees are paid (government contributions should go directly to the government's designated account), who carries out due diligence, and what happens if an application is refused. Mirabello Consultancy is a Swiss advisory firm with offices in Zurich, Dubai and Hong Kong SAR, a member of the Investment Migration Council (IMC) with ACAMS-certified compliance expertise, and advises in 11 languages. We recommend a programme only when it genuinely fits your family.
