Compare second passports for Swiss citizens, from São Tomé and Nauru to the Caribbean. Explore costs, dual citizenship, tax considerations and your Plan B.
If you hold a Swiss passport, you are starting from a position many people spend years trying to reach.
You have a country you can return to, a valuable travel document, and institutions that give people good reasons to plan their lives in Switzerland. You might be perfectly happy in Zurich, Geneva, Zug, or Lugano. Your business works. Your children are settled. Moving is not on the agenda.
Why think about a second citizenship?
Because being happy with your current position and wanting more options can coexist.
A second passport can give you another country where you belong, another government responsible for issuing your travel documents, and another place to build a future if your circumstances change. You can add those options while keeping the Swiss citizenship you already value.
For Swiss citizens, that is the strongest argument. Your existing passport already handles most ordinary travel needs. A second citizenship should add something meaningful beyond another cover in the drawer.
My view is that Swiss applicants should focus on geographic diversification, family rights, and the practical value of having a Plan B. Start with the gap in your current position, then choose the country that fills it.
São Tomé and Príncipe and Nauru are useful starting points for a comparatively affordable additional nationality. Vanuatu offers another Pacific option. St. Kitts and Nevis, Dominica, Antigua and Barbuda, and Grenada belong in a Caribbean comparison. El Salvador and Turkey are worth considering when you have a clear reason to want those countries specifically.
The right answer depends on what you want to add to your Swiss citizenship, how much you are comfortable spending, and what ongoing commitments your family can realistically manage.
The figures below are starting contributions or qualifying investments in US dollars. They exclude licensed agent fees and are not all-in application prices. Government charges, document costs, passport fees, and other applicable expenses are additional.
| Country | Starting contribution or investment | Why a Swiss citizen might consider it | Main consideration |
|---|---|---|---|
| São Tomé and Príncipe | $90,000 contribution for one applicant | A comparatively affordable additional nationality outside Europe | Assess the practical value of the citizenship beyond its price |
| Nauru | $90,000 contribution under the temporary 2026 offer | No residence requirement and a process compatible with staying in Switzerland | Promotional pricing has a deadline; additional fees apply |
| Vanuatu | $130,000 Development Support Program contribution | A Pacific citizenship without a conventional residence period | In-person passport biometrics and limits on travel access |
| Dominica | $200,000 contribution for one applicant | A lower starting contribution among established Caribbean programs | Compare the completed family cost and current travel rights |
| Antigua and Barbuda | $230,000 National Development Fund contribution | An option worth assessing for families | A short physical-presence obligation applies |
| Grenada | $235,000 National Transformation Fund contribution | A Caribbean nationality and possible future base | Swiss citizens already have US E-2 treaty nationality eligibility |
| St. Kitts and Nevis | $250,000 Sustainable Island State Contribution | An established program with a long operating history | Higher contribution and evolving presence requirements |
| Turkey | $400,000 qualifying property investment | Citizenship in a country where you may also want an asset or a home | Three-year property holding period and investment risk |
| El Salvador | $1 million Freedom Passport contribution | A country-specific choice for founders and families interested in Central America | Substantial non-refundable cost and absence rules for naturalized citizens |
Nauru's official contribution schedule identifies the $90,000 amount as a temporary offer for qualifying filings before December 31, 2026. Budget using the terms that apply when your application will actually be submitted.
A contribution and a property investment also need different financial treatment. The former is money you spend. The latter ties up capital in an asset whose eventual value and sale are uncertain.
You do not need to convince yourself that Switzerland is a bad place to live before a second citizenship makes sense.
That is an unhelpful way to approach the decision. If you enjoy your life in Switzerland, keep building it. A Plan B gives you more freedom to adapt later.
Your reasons might be personal rather than political. A spouse could want to spend more time near family overseas. Your children could eventually build their careers elsewhere. A business opportunity could move your attention to another region.
Citizenship can give those future decisions a different starting point. You would already have a legal relationship with another country instead of beginning every conversation as a prospective immigrant.
Swiss citizenship is valuable. It is also a single nationality, tied to one state and its decisions.
You can recognize the strengths of Switzerland while choosing to spread some of that dependence. Business owners do this elsewhere in their lives: they build financial reserves, maintain alternative suppliers, and avoid unnecessary reliance on a single customer.
A second citizenship applies a similar principle to where you can belong.
It will not eliminate geopolitical risk. The new country has risks of its own. What it can do is give you another set of rights in a different place, so that fewer of your future choices depend entirely on one government.
Swiss citizens are not EU citizens merely by virtue of being Swiss. Switzerland's European arrangements have their own legal basis.
The Swiss government's EU/EFTA entry and residence guidance explains the opportunities and conditions available to Swiss nationals through the relevant agreements. Those existing rights should be included in any assessment of what you need next.
If your goal is to live in a nearby European country, you may already have a workable route. If your goal is to establish an option beyond Europe, another nationality in a different region may be more relevant.
Start with the geography you actually want to add. Buying overlapping rights simply because a passport has a familiar name is not much of a strategy.
Citizenship applications take time. Documents must be collected, funds explained, and government checks completed. Family eligibility can also change as children grow older.
Those are good reasons to plan early. They are not reasons to rush into the first program you see.
The advantage of preparing while life is calm is that you can compare carefully. You can choose an appropriate budget, visit a possible destination, and ask the questions that are easy to overlook when everything feels urgent.
Yes. The State Secretariat for Migration confirms that Switzerland has recognized dual nationality without restriction since January 1, 1992. Acquiring another nationality does not, in itself, require a Swiss citizen to give up Swiss citizenship.
That makes the starting position relatively straightforward compared with countries that generally withdraw nationality when an adult voluntarily acquires another.
Still, check the rules of the country you plan to join. Swiss permission to hold multiple nationalities does not determine the other country's position.
A Swiss applicant may have a spouse who holds a more restrictive nationality. A child may already have citizenship through the other parent. You may personally hold another nationality alongside your Swiss one.
All of those relationships matter.
Use the CitizenX Dual Citizenship Index as a starting point, then resolve any nationality-specific restrictions before applying. Do not assume everyone in the household has the same legal position because everyone lives at the same address.
If your family later lives overseas, maintaining civil-status records becomes particularly important.
The Swiss government's guidance on loss of nationality explains that a child born abroad to a Swiss parent who also holds another nationality can lose Swiss citizenship at age 25 unless the relevant registration or declaration has been made.
The practical lesson is to register births and keep family records current. Do not assume a child's nationality will remain secure simply because a parent has a Swiss passport.
This is especially relevant when a second citizenship is intended to benefit future generations. Preserving the Swiss side of the family's rights deserves as much care as acquiring the new nationality.
São Tomé and Príncipe deserves attention from Swiss citizens who want an additional nationality without committing several hundred thousand dollars.
Its official National Transformation Fund schedule lists a $90,000 contribution for a single applicant and $95,000 for a family of two to four. The schedule separately lists a $5,000 submission fee per application and $750 in citizenship-document charges per applicant.
For one person, those published components total $95,750 before licensed agent fees and other applicable expenses. The starting contribution alone is not the finished price.
Your Swiss passport may already cover nearly all of your ordinary travel needs. That gives you room to evaluate another citizenship on a different basis.
You might want another place where you have citizenship rights, a legal connection outside Europe, or an option that does not depend on maintaining a foreign job or residence permit.
For that objective, the financial commitment and practical administration become more important than adding another long list of visa-free destinations.
The program's published guidance states that physical residence or relocation is not required during or after the application process. You can therefore investigate citizenship without first planning a multiyear departure from Switzerland.
Be clear about whether São Tomé is a nationality you want to hold, a country you might eventually live in, or both.
If relocation is part of your plan, investigate healthcare, schools, transport, and connectivity. Spend time understanding everyday life. A passport does not tell you whether a place works for your family.
Also separate approval from passport production and delivery when discussing the timeline. A fast decision and a travel document in your hand are different milestones.
My view: São Tomé is a sensible first comparison for a Swiss citizen seeking a comparatively accessible second nationality. Its value should come from the option it adds, rather than assumptions about what the country will become.
Nauru offers another route worth comparing early, particularly if you want to continue living in Switzerland.
The Economic and Climate Resilience Citizenship Program connects contributions with the country's development and climate-resilience needs. Its temporary 2026 principal-applicant contribution is $90,000, with separate application and other charges.
The official program FAQ confirms that no residence period is required. Principal applicants must attend an interview, which can be conducted virtually or at an approved location. The oath remains part of the process, with specified alternatives available when it cannot be taken in person.
For a business owner in Zurich or a family with children at school in Geneva, the main cost of a citizenship process may include time and attention as well as money.
A route that avoids years of residence can be easier to fit around an established life. You can progress the application without moving your business, changing schools, or maintaining a foreign property simply to qualify.
That is a meaningful benefit, but it still needs to be weighed against the nationality's actual use to you.
Look at where you travel, where you might live, and what you want another nationality to accomplish. A passport ranking does not answer those questions.
If you retain your Swiss citizenship, you may continue using Swiss documents for much of your travel. Nauru would add another nationality and a different geographic connection.
The program FAQ also provides for passport renewal through the program office or diplomatic channels without a local address. For someone planning to remain abroad, a workable renewal process is part of the decision.
My view: Nauru is particularly relevant when you want another citizenship with little disruption to your existing life. Compare its completed household cost with São Tomé before deciding between them.
Vanuatu remains relevant to Swiss citizens considering a second nationality outside Europe.
CitizenX's Vanuatu program guide lists a $130,000 starting contribution for a single applicant under the Development Support Program. There is no conventional residence qualification, but passport issuance involves an in-person biometric appointment.
Confirm the authorized enrollment locations and attendance requirements for every family member. An application that is managed remotely can still require you to travel for a specific step.
Vanuatu's older travel benefits should not be carried into a current comparison.
The European Council ended Vanuatu's visa exemption in December 2024. The UK introduced a visa requirement for Vanuatu nationals in 2023.
Those changes matter if you want the second passport to function independently for European and UK travel. They may be less central if you retain your Swiss nationality and mainly want another citizenship for different reasons.
You should still understand the limitation before paying. A benefit becoming less important to your case does not make it a benefit the passport still provides.
Ask for an end-to-end timeline covering document preparation, government review, citizenship formalities, biometrics, and passport delivery.
A published approval estimate is not a promise that you can board a flight with your new passport on that date. Family coordination and appointment availability also matter.
My view: Vanuatu can be useful when you want a Pacific nationality and the practical process suits you. It should be chosen with a clear understanding of current travel rights and the completed application cost.
St. Kitts and Nevis has operated its citizenship-by-investment program since 1984. Its Sustainable Island State Contribution starts at $250,000, before additional applicable charges.
For applicants who prefer a program with a long operating history, it belongs on the shortlist.
A Swiss applicant might place value on a country they can imagine visiting regularly, a program that fits the family they want to include, and a second passport they could use independently when needed.
Those can be reasonable reasons to spend more. The question is whether St. Kitts delivers benefits that matter to your circumstances.
You already have a strong Swiss nationality. There is little reason to pay a premium solely because an advertisement describes another passport as powerful.
Compare the actual destination rules, family provisions, administrative process, and ongoing obligations. The difference should be useful to you.
The St. Kitts and Nevis government announced residence and biometric reforms in January 2026. That announcement should not be mistaken for a complete explanation of how every requirement applies to a particular application.
Obtain the current implementation terms before submitting. Ask separately about biometric enrollment and any residence or connection obligation.
My view: St. Kitts is worth comparing when an established Caribbean program is a priority and you are comfortable with the higher contribution. Make the premium earn its place in your plan.
Dominica's Economic Diversification Fund route starts at $200,000 for one applicant. Older references to a $100,000 contribution are outdated.
For a Swiss citizen considering the Caribbean, that makes Dominica a useful price comparison with the other established programs.
A single-applicant minimum is only the beginning of the comparison. A spouse, adult children, or parents can change the contribution and the additional charges.
Build the comparison around the same household in every country. Otherwise you can end up comparing one program's individual price with another program's family amount.
The people you want to include also need to qualify. Dependency definitions and age limits can be more decisive than the difference between headline prices.
Dominica's passport does not carry all the privileges described in older marketing. The UK's July 2023 rule changes introduced a visa requirement for Dominican nationals.
That may have limited impact on a Swiss citizen who retains and uses their Swiss passport. It remains relevant if your objective includes travelling independently on the new nationality.
My view: Dominica is worth examining for applicants who want a Caribbean citizenship at a comparatively lower contribution. Judge it against your own Plan B requirements, with current travel rules and a completed quote.
Antigua and Barbuda's National Development Fund contribution starts at $230,000.
Its family provisions make it worth reviewing alongside the other Caribbean options. The right comparison includes every person you want in the application and all the charges attached to that household.
The official passport guidance links first renewal to spending a total of five days in Antigua and Barbuda during the first five years after obtaining citizenship. Applicable exemptions should be checked for individual family members.
For a Swiss family able to arrange a visit, this may be a modest commitment. It is still an obligation to plan and document.
If you need a route with no physical presence at all, Antigua deserves a different assessment from a program that expressly has no residence requirement.
A visit requirement can also prompt a useful conversation. Would you actually enjoy spending time there? Could your work continue? Would the family be comfortable if you wanted to stay longer?
Those questions help turn an abstract passport purchase into a practical choice.
My view: Antigua should be compared at the household level. A small difference in the contribution can become much less important once you account for who qualifies, what each person costs, and how the family would use the citizenship.
Grenada's National Transformation Fund route starts at $235,000 under the Investment Migration Agency's published program terms.
For a Swiss audience, one of its most frequently advertised benefits needs context.
Switzerland already appears on the US State Department's E-2 treaty-country list.
If you want to establish or acquire a business in the United States, assess whether you can pursue the E-2 route using your existing Swiss nationality. You still need to meet the visa's business, investment, and other requirements, but an additional citizenship is not generally necessary to satisfy the nationality element.
A person relying on treaty nationality acquired through financial investment also generally faces a three-year continuous-domicile requirement under the US E-2 rules, subject to the applicable exceptions.
Buying a passport and waiting three years while living elsewhere does not itself establish that domicile.
You may want Grenadian citizenship because the country appeals to you, its family eligibility fits, or it adds the geographic option you want.
Those are reasons to evaluate it on its own merits. They do not depend on presenting US treaty eligibility as something a Swiss citizen lacks.
Grenada's residence reform also requires attention. Its August 2026 official circular deferred implementation pending regional arrangements and a formally agreed commencement date.
My view: consider Grenada as a Caribbean nationality and potential future base. For Swiss applicants, the E-2 pitch should rarely be the starting point.
El Salvador's Freedom Passport pathway requires a $1 million non-refundable contribution. CitizenX's El Salvador program overview describes the route and contributions in Bitcoin or USDt.
That price puts it in a different category from the more accessible programs in this comparison.
A Swiss founder or Bitcoin holder might be interested because they already spend time in El Salvador, have business relationships there, or want a future base in Central America. Those are more persuasive reasons than a generic promise of freedom.
Switzerland already offers many of the things people seek when planning internationally. A million-dollar contribution should add something you value enough to justify it.
Perhaps the answer is a community you want to join or a country where you can imagine your family's next chapter. If the answer is simply “another passport,” start by comparing less expensive routes.
The expedited naturalization framework in Decree No. 918 provides a route for qualifying participants in government investor or donor programs. It is distinct from waiting through an ordinary residence-based naturalization period.
El Salvador's rules for naturalized citizens matter if you intend to keep your life in Switzerland.
Article 94 of the Salvadoran Constitution contains loss-of-nationality provisions after more than two consecutive years residing in the country of origin or more than five consecutive years absent from El Salvador, unless permission is granted under the law.
Have Salvadoran counsel resolve how those provisions apply to you and what permission is needed. An occasional visit should not be assumed to answer every part of the rule.
My view: El Salvador can be compelling for the right person. The decision should rest on a clear country-specific reason and a documented plan for retaining the citizenship while living where you choose.
Turkey, officially Türkiye, offers an investment route rather than relying only on a non-refundable contribution.
The Turkish government's guidance sets a minimum of $400,000 for qualifying real estate, with a restriction on resale for at least three years. Investment certification, the relevant residence permission, and government approval form part of the exceptional citizenship process.
This can suit someone who wants citizenship and independently has a reason to own property in Turkey.
I would evaluate the citizenship first and the investment second.
Does Turkish citizenship provide rights you want? Does the property make sense at the price? Can you manage the asset, accept the holding period, and tolerate the possibility of an unfavorable sale?
A future resale can recover capital. It does not guarantee that the citizenship has cost you nothing. Transaction expenses, taxes, maintenance, exchange rates, and market conditions all affect the result.
For a Swiss investor used to assessing assets carefully, the nationality benefit should not become an excuse to accept a weak property purchase.
My view: Turkey belongs on the shortlist when you want that country and are comfortable with the investment. For a simple additional nationality with limited administration, a contribution route may be a better fit.
The Federal Tax Administration's overview of the Swiss tax system explains the roles of the Confederation, cantons, and communes. Your tax position depends on the applicable rules and your circumstances, rather than simply the passports you hold.
If you continue living in the same Swiss home and managing the same business, acquiring a foreign citizenship does not by itself change that position.
If you later move abroad, the departure needs its own assessment. Your continuing Swiss connections, property, business interests, and the destination country's rules can all matter.
Keep the citizenship decision focused on the rights it adds. Obtain a separate analysis of any proposed relocation and tax consequences before acting.
A Swiss resident concerned primarily about domestic living costs or taxes should examine their actual options within Switzerland as well as abroad.
Moving within the country, changing residence internationally, and acquiring another citizenship are different decisions. One does not automatically accomplish the others.
If your real goal is geographic independence, citizenship may fit. If your immediate goal is to improve a specific financial situation while remaining Swiss-resident, begin with that problem and the advice it requires.
I would not spend six figures on a passport to solve something that does not depend on nationality.
Acquiring another citizenship does not automatically exempt a Swiss citizen from military or related obligations.
Swiss official guidance on military service abroad describes distinct rules for living overseas, returning to Switzerland, and dual nationals who have already completed service elsewhere. Swiss men subject to service who deregister and plan to spend more than twelve consecutive months abroad must address the relevant overseas exemption procedure with their cantonal command.
The practical point is to resolve your status through the responsible authority. A second passport is not a substitute for doing so.
Also check whether the new citizenship could create obligations of its own for you or your children. Age, residence, naturalization status, and the applicable law can affect the answer.
A bank will still assess your residence, tax status, source of wealth, business activities, and other relevant circumstances.
Your second nationality can be part of that profile. It does not guarantee an account or allow you to present an inaccurate picture of where you live and pay tax.
If a particular banking relationship is central to your plans, investigate it directly. Avoid buying citizenship on an assumption that a specific institution will accept you afterward.
Write down what you want the additional citizenship to do.
Perhaps you want a place outside Europe where you can live indefinitely as a citizen. Perhaps you want another nationality for your family without relocating now. Perhaps you already feel connected to a country and want that relationship to become permanent.
A precise objective makes the comparison easier. It also makes it easier to reject benefits you do not need.
You do not need to acquire a second nationality every time you want to live abroad. Your Swiss citizenship may already support a suitable residence application in your preferred destination.
If the immediate goal is to move, assess the residence route directly. Citizenship may still be valuable as a longer-term option, but it should earn its place in the plan.
The country whose citizenship you obtain and the country where you choose to live do not have to be the same. Keeping that possibility open can help you choose each for the right reason.
List the people you want to include, their ages, existing nationalities, and dependency circumstances.
Then ask how each program treats that household. An adult child or an older parent can change which route is practical. A spouse's nationality can introduce restrictions that do not apply to you.
Also ask what happens after a later birth or marriage. Transmission to children, registration procedures, and any generational limits should be understood rather than summarized as “citizenship forever for everyone.”
Consider appointments, visits, investment holding periods, passport renewals, and any permissions needed to remain abroad.
For some families, an occasional Caribbean trip is easy. For others, coordinating travel with work, school, and care responsibilities is a significant burden.
Choose based on the life you actually have. A slightly cheaper program is not necessarily the better choice if its practical requirements consistently create problems.
A Plan B should add resilience to your life. It should leave you with enough liquidity to use the option if you ever need it.
Budget beyond the application. If relocation is a serious possibility, accommodation, insurance, schooling, and a financial buffer may matter as much as the citizenship contribution.
One carefully chosen nationality and a workable relocation plan can be more valuable than several passports acquired without a clear purpose.
Review your Swiss citizenship, any other nationality you hold, and the position of each dependent. Establish whether the chosen program accepts your circumstances and whether an application could affect another existing citizenship.
Get a written breakdown showing the qualifying contribution or investment, government charges, licensed agent fees, document expenses, and expected appointment costs.
Understand when payments are due and which are non-refundable. Compare the same household across the shortlist.
Typical applications involve passports, birth and marriage records, police certificates, and evidence of lawful funds. Translation and legalization requirements depend on the country and the documents involved.
An entrepreneur should be ready to explain how business wealth became the personal funds used in the application. Digital-asset proceeds should also have a clear, documented history.
Government review is a substantive part of the process. Having enough money and holding a Swiss passport do not guarantee approval.
Provide accurate information, including any matters the application asks about that could require explanation. Your adviser can assess the facts properly only if they have the full picture.
Some contribution programs request the main contribution after approval in principle. Investment routes may require the qualifying asset to be acquired earlier.
Follow the rules for the route you have chosen. A sequence that applies in one country should not be assumed to apply in another.
An oath, civil registration, biometric appointment, or passport application may remain outstanding after the main approval.
Treat citizenship approval and passport delivery as separate stages. Make travel plans around documents you actually hold and can use.
Keep certificates safe, maintain renewal reminders, and record any continuing requirements.
If your second country is part of an emergency or retirement plan, learn how life there would work. Identify realistic accommodation, medical services, and routes for reaching it. The legal right is the foundation; preparation makes it useful.
São Tomé and Nauru are strong starting points for a comparatively affordable additional nationality. Caribbean programs deserve comparison when their family provisions and practical benefits justify the cost. El Salvador and Turkey make more sense when you specifically want those countries. Vanuatu can suit applicants comfortable with its current travel rights and appointment requirements.
Acquiring another nationality does not by itself require you to give up Swiss citizenship. Switzerland permits dual nationality. Check the other country's rules and any additional nationality you already hold before proceeding.
Swiss citizens already benefit from European arrangements covering movement and residence, subject to the applicable conditions. Swiss nationality is not EU nationality, but you should assess your existing rights before paying for an additional citizenship primarily for European access.
Swiss nationality already satisfies the treaty-nationality element for an E-2 application. You still need to meet all the other visa requirements. Grenada should be evaluated for the citizenship benefits it adds beyond treaty eligibility you already have.
Several economic citizenship routes do not require you to relocate for years. Some still require interviews, biometric appointments, an oath, or visits. Confirm the complete procedure and ongoing obligations for your household.
The passport alone does not change your Swiss tax residence or existing liabilities. A genuine move abroad requires separate planning based on your personal, family, business, and property circumstances.
No automatic exemption follows simply from acquiring another passport. Overseas residence, prior service in another country, and applicable agreements can affect the position. Resolve your status with the responsible Swiss authority before making plans around an exemption.
That depends on each country's nationality rules and the family's circumstances. Registration can be essential. Swiss rules concerning children born abroad who also hold another nationality deserve particular attention, including the age-25 forfeiture provision where the necessary registration or declaration has not been made.
The approach discussed here is about adding rights while retaining your Swiss nationality. Renunciation is a separate and consequential decision. It is not a routine step in building a second-citizenship Plan B.
Swiss citizens do not need to manufacture a crisis to justify thinking strategically about nationality.
You can value Switzerland, keep your life there, and still decide that your family would benefit from a second country where they belong. The two choices support each other: an additional option can make staying a more deliberate decision.
I would start by defining the rights you want to add. Compare São Tomé and Nauru for an accessible additional nationality. Examine the Caribbean when its practical benefits fit your household. Consider Vanuatu, El Salvador, and Turkey according to the specific role each could play in your life.
Then make sure the cost and obligations are proportionate. Protect your existing rights. Know how you would use the new ones.

A second citizenship should give you more room to choose your future, wherever you decide to live it.
