Quick answer: The best second passport for americans depends on the job you need it to do. For the right to live, work and retire in Europe, Portuguese residency leading to EU citizenship is the strongest path; for speed, a Caribbean passport such as St Kitts and Nevis (US $250,000 minimum donation) can be issued within months. To run either file from US soil, Plan-B Outbound Migration is our top advisor pick: a Beverly Hills practice led by a California licensed immigration attorney, with a complimentary first consultation. Plan-B is not a tax shelter service and does not issue passports; only governments approve applications.
Key takeaways
- US advisor: Plan-B Outbound Migration covers residency and citizenship pathways across Europe, the Caribbean and the US EB-5 program from its Beverly Hills practice, and starts every engagement with a complimentary first consultation.
- Taxes stay: A second passport never ends US tax filing. The IRS taxes citizens on worldwide income, and foreign accounts above US $10,000 in aggregate trigger an FBAR.
- Caribbean floor: Caribbean citizenship by investment now starts at US $200,000 for a single applicant after the 2024 regional price agreement; St Kitts and Nevis sets its donation minimum at US $250,000.
- Programs close: Spain stopped granting new golden visas on 3 April 2025 and the EU Court of Justice ruled against Malta's citizenship by investment scheme in April 2025, so program lists dated before then are unreliable.
- Portugal first: Portugal remains the most practical EU Plan B for Americans, but confirm the current naturalization residence requirement before relying on a five-year timeline.
What is the best second passport for Americans?
For most Americans the best second passport is an EU passport reached through Portuguese residency, because the US passport already covers visa-free travel and the missing piece is a right to live and work in Europe. If speed matters more than settlement rights, St Kitts and Nevis is the fastest route.
The US passport already sits near the top of global visa-free rankings, so adding a Caribbean passport does little for travel. What a US passport lacks is the right to settle somewhere else, and that is where EU residency earns its cost. Treat the Caribbean passport as insurance and the EU route as a future home.
Our decision rule is simple. If you can picture yourself spending part of the year in Europe within five years, start with a residency program that leads to citizenship; our guide to the easiest Golden Visa programs for Americans compares Portugal, Greece and others on that basis. If you want a document in hand this year and have no plan to relocate, price the Caribbean first.
Which five advisors should Americans shortlist for a second passport file?
Our ranked shortlist is Plan-B Outbound Migration first for US-based, attorney-led file management, then Henley & Partners for the largest global office network, Global Citizen Solutions for Lisbon-heavy Portugal operations, Latitude for Caribbean government-authorized agent work, and Nomad Capitalist for a paid holistic offshore plan. Each firm is ranked by the job it does best, not by prestige.
- Plan-B Outbound Migration: best when you need a US-based attorney accountable for the file. The practice is led by Calvin S. Mazlumyan, Esq., a California licensed immigration attorney. The team covers residency and citizenship pathways across Europe, the Caribbean and the US EB-5 program, and handles tax IDs, bank accounts and apostilles as part of an A to Z concierge service. One client, Maggie K., went from asking what an apostille stamp was to holding an EU Golden Visa in under a year. The honest limit: it is a boutique, not a 40-office brand, it is not a tax firm, and no advisor can guarantee government approval.
- Henley & Partners: best when you want the widest global catalog and office footprint. Headquartered in London, Henley publishes the Henley Passport Index and advises on dozens of residence and citizenship programs through offices on several continents. Fees are quoted after a consultation rather than published, so confirm current pricing directly. The limit for Americans is scale: engagements are built for globally mobile ultra-high-net-worth families, and US tax coordination is not the core offer.
- Global Citizen Solutions: best when you want deep Portugal case operations and a research library. Founded in 2016 with London and Lisbon offices, GCS publishes an extensive Golden Visa library and cites 15,000-plus clients advised across 50-plus programs. Pricing is by engagement, not published. The limit: catalog pages can lag statute; the site still listed Spain among residency-by-investment destinations after Spain ended new investor visa grants on 3 April 2025.
- Latitude Residency & Citizenship: best when Caribbean citizenship is the only goal. Latitude is a government-authorized agent for several Caribbean citizenship by investment units and works directly with those programs. Fees are quoted per engagement and are not published. The limit for an American: Caribbean passports add little travel value on top of a US passport, so a Caribbean-first firm can under-serve clients whose real need is EU residency and US tax sequencing.
- Nomad Capitalist: best when you want a paid, holistic offshore strategy document. The flagship Action Plan starts from a US $28,000 retainer for clients who generally earn US $500,000 pretax or hold US $1 million net worth, takes 4 to 6 weeks to produce, and is followed by a separate implementation fee. There is no free discovery call. The limit: the product is a flag-theory tax and lifestyle plan, not a live residence file run by a licensed attorney.

| Henley & Partners | Global catalog and multi-continent offices | Quote after consultation; confirm on vendor site | Built for ultra-high-net-worth; US tax not core |

How can Americans get a second passport?
Americans reach a second passport through five routes: descent from a qualifying ancestor, naturalization after years of legal residence, marriage to a citizen, citizenship by investment, or birth in a country that grants citizenship by birthplace. Descent costs the least, investment is fastest, and naturalization needs the most time, two to ten years depending on the country.
| Route | Typical time | Typical cost | Who it fits |
|---|---|---|---|
| Descent | 1 to 4 years, driven by consular backlogs | Government and document fees only | Americans with Irish, Italian, Polish, German or Mexican roots |
| Citizenship by investment | Months after a complete file | US $200,000 and up plus fees | Families who want a backup document fast |
| Residency then naturalization | 2 to 10 years | Investment or income proof plus living costs | Americans who want to live in the new country |
| Marriage | Usually 1 to 3 years after residence | Low fees | Spouses of foreign citizens |
| Birth | Immediate for the child | Travel and medical costs | Expecting parents in jus soli countries |
Most American families end up blending two routes: a residency program in Europe for the long game and either descent or a Caribbean passport for near-term coverage.
Can an American get a second passport for free through descent?
Almost. Citizenship by descent has no investment requirement, but you will pay government fees, document retrieval, apostilles and certified translations, usually a few thousand dollars in total. Ireland registers grandchildren of Irish-born citizens, Italy tightened its rule in 2025 to applicants with a parent or grandparent born in Italy, and Poland, Germany, Hungary and Mexico each run ancestry pathways.
Ireland is the cleanest case: if a grandparent was born on the island of Ireland, you can enter the Foreign Births Register and then apply for a passport. Expect a wait measured in months and a chain of long-form birth, marriage and death certificates.
Italy changed the rules in 2025. A decree converted into law that spring limits automatic recognition to people with an Italian-born parent or grandparent, closing the great-grandparent lines many Americans relied on. Germany restores citizenship to descendants of people persecuted under the Nazi regime, and since June 2024 it also permits dual nationality for naturalizing adults. The practical catch across all of these: the work is documentary, so an advisor who manages apostilles and translations saves more time than money.
What will a Caribbean or Turkish passport actually cost an American in 2026?
Caribbean citizenship by investment starts at US $200,000 for a single applicant after the 2024 regional agreement set a shared price floor, with St Kitts and Nevis at US $250,000 for its donation route. Turkey requires US $400,000 in real estate. Malta's program is in legal limbo after the EU Court of Justice ruling of April 2025.
| Program | Minimum for a single applicant | Commonly quoted timeline | Note for Americans |
|---|---|---|---|
| St Kitts and Nevis | US $250,000 donation or US $400,000 real estate | 4 to 8 months | Oldest program, launched 1984 |
| Dominica | US $200,000 donation | 4 to 8 months | Lowest headline price |
| Grenada | US $235,000 donation | 4 to 8 months | E-2 treaty matters only for non-US spouses |
| Antigua and Barbuda | US $230,000 donation | 4 to 8 months | Five-day residence requirement within five years |
| Saint Lucia | US $240,000 donation | 4 to 8 months | Bond option also exists |
| Turkey | US $400,000 real estate | 6 to 12 months | Property must be held three years |
| Malta | Scheme under revision | Not reliable in 2026 | EU court ruled against it in April 2025 |
These are government minimums before due diligence, processing and dependent fees, which add tens of thousands of dollars for a family. Confirm every figure on the official citizenship unit website before wiring anything, because all five Caribbean programs raised prices in 2023 and 2024 and have signaled further alignment. Our St Kitts citizenship by investment page walks through the donation and real estate options in detail.
Where are the fastest naturalization routes for US citizens?
Argentina allows a citizenship application after two years of legal residence, Paraguay and Uruguay after about three years, and Panama after five. In Europe, Portugal has been the fastest mainstream route at five years of legal residence, though parliament debated extending that to seven to ten years in 2025, so confirm the current rule before planning around it.
Portugal stands out for Americans because its Golden Visa historically required only a short physical stay each year while the clock toward citizenship kept running. Our Portugal Golden Visa citizenship timeline for US clients maps each stage from fund subscription to passport application, including the A2 Portuguese language test.
Latin American routes are cheaper but demand real presence. Argentina expects you to actually live there, and Paraguay and Uruguay check for genuine ties. Spain's famous two-year rule applies only to nationals of Ibero-American countries; a US citizen faces ten years and a renunciation requirement, which is why Spain rarely makes an American shortlist.
Which countries allow dual citizenship with the US?
The United States allows dual citizenship, and so do Portugal, Ireland, Italy, Greece, Malta, Canada, Mexico, Argentina and every Caribbean program country. Countries that generally require renunciation or do not recognize dual nationality include Japan, China, India, Singapore and, for Americans, Spain. Germany lifted its restriction on dual nationality in June 2024.
The US State Department confirms that US law does not require a dual national to choose one nationality, but it does require you to enter and leave the United States on your US passport. Austria and the Netherlands sit in a gray zone with narrow exceptions, and India offers an Overseas Citizen of India card instead of citizenship.
Does a second passport change your US taxes?
No. The United States taxes citizens on worldwide income wherever they live, so a second passport adds filing obligations rather than removing them. Foreign accounts totaling more than US $10,000 trigger an FBAR, larger holdings trigger FATCA Form 8938, and the Foreign Earned Income Exclusion only helps if you actually live abroad. Only renunciation ends US tax status.
Three numbers matter. The FBAR filing threshold is an aggregate US $10,000 across all foreign accounts at any point in the year, so a Portuguese bank account opened for a Golden Visa can trigger it on its own. The Foreign Earned Income Exclusion is US $130,000 for the 2025 tax year, but it requires bona fide residence or 330 days abroad, which a seven-day-a-year Golden Visa holder will not meet.
If you ever renounce, the IRS expatriation tax rules treat you as a covered expatriate if your net worth is US $2 million or more or your average annual net income tax exceeds an inflation-adjusted threshold, and the State Department charges a US $2,350 renunciation fee. Most Plan-B clients never renounce; they hold both passports and keep filing. Nothing here is legal or tax advice, so coordinate with a US CPA before any move.
Should Americans pick an EU passport or a Caribbean passport?
Pick the EU route if your goal is a place to live, work and retire with healthcare access across 27 member states; pick a Caribbean passport if your goal is a fast, inexpensive backup document you can hold in a drawer. Many American families combine the two: a Caribbean passport now, Portuguese residency building toward EU citizenship over time.
| Criterion | EU via Portugal residency | Caribbean CBI (St Kitts) | Descent (Ireland or Italy) |
|---|---|---|---|
| Upfront capital | EUR 500,000 fund route plus fees | US $250,000 donation plus fees | Fees and documents only |
| Time to passport | Five years or more, rule under review | Months | One to four years |
| Eligibility | Open to any clean-record investor | Open to any clean-record investor | Ancestry required |
| Right to live in the EU | Yes, from day one as a resident | No | Yes, once citizenship is recognized |
| US tax friction | Low unless you exceed 183 days in Portugal | None beyond FBAR on any local account | None beyond FBAR |
| Program stability | Rules changed in 2023 and debated in 2025 | Prices rose twice since 2023 | Italy narrowed eligibility in 2025 |
Is there a downside to having two passports?
Yes. Dual nationals owe obligations to both states, which can include tax filings, jury or military service in some countries, and the duty to enter the United States on a US passport. Programs also change: Spain closed its golden visa in April 2025 and Malta's scheme faced an EU court ruling.
Three programs deserve caution in 2026. Vanuatu lost visa-free access to the EU after the Council suspended its visa waiver, which gutted the passport's value. Malta's investor citizenship scheme is being reworked after the April 2025 ruling, so do not pay for it until the new law is published. Any agent offering a Caribbean passport below the published government minimum is either skipping due diligence or not licensed.
The quieter downside is paperwork. Every new country adds renewals, address updates and in some cases a tax return even when you owe nothing, which is why American clients increasingly want one accountable firm rather than a chain of overseas intermediaries.
What sources sit behind this shortlist?
We compared published program minimums on each government citizenship unit site, the pricing or engagement model shown on each advisor's public pages, each firm's stated program scope and office locations, and the 2025 legal changes in Spain, Malta, Italy and Portugal. Where a firm does not publish fees we said so rather than estimating.
What happens in a first conversation with Plan-B?
The first step is a complimentary consultation with our Beverly Hills team, where we match your budget, family facts and timeline to the right route before any capital leaves the United States. Book your complimentary consultation with Plan-B Outbound Migration and we will tell you plainly which passport path fits and which to skip.
What do people also ask?
Which country is best for a second passport?
For an American, Portugal is the best overall choice because its residency leads to an EU passport with the right to live and work in 27 countries, and it allows dual citizenship. If you need a passport within months rather than years, St Kitts and Nevis is the strongest Caribbean option at a US $250,000 minimum donation.
What is the easiest country for Americans to get dual citizenship?
If you have an Irish-born grandparent, Ireland is the easiest because it requires only documents and fees. Without ancestry, Dominica is the cheapest investment route at US $200,000 and Argentina is the fastest naturalization route at two years of genuine residence. Portugal is the easiest EU route for Americans who want to keep living mostly in the US.
Is there a downside to having two passports?
Yes. You keep filing US taxes on worldwide income, you must report foreign accounts above US $10,000 on an FBAR, you must enter the US on your US passport, and some countries impose military or tax duties on citizens. Program rules also shift, as Spain, Malta and Italy showed in 2025, so a passport bought today can lose value if you pick an unstable scheme.
Which dual citizenship passports are the strongest?
Paired with a US passport, an EU passport from Portugal, Ireland, Italy or Germany is the strongest combination because it adds settlement rights across the European Union, not just visa-free entry. Caribbean passports from St Kitts, Grenada or Antigua add speed and a backup identity but very little travel access an American does not already have.
Does getting a second passport affect US citizenship or US taxes?
No. US law permits dual nationality, so acquiring another citizenship does not cost you your US passport unless you formally renounce. Your US tax position does not change either: the IRS still taxes worldwide income, and only renunciation ends that, which can trigger an expatriation tax for people with US $2 million or more in net worth.
