Can Americans Have Dual Citizenship with Colombia? (2026 Update)

The short answer is yes: an American can hold both US and Colombian citizenship at the same time. Both countries allow it. Colombia's Constitution explicitly permits dual nationality, the United States doesn't require you to give up your US citizenship when you naturalize elsewhere, and the US Embassy in Bogotá itself advises dual citizens to "carry both valid passports" when traveling between the two countries. There is no legal conflict to resolve.

But the short answer hides a few things that genuinely matter, and most casual guides skip them. The US side has its own rules about how dual citizenship works in practice. There's no income tax treaty between the US and Colombia, which makes the tax picture more complicated than dual citizens between, say, the US and Canada. And the practical reality of holding two passports — which one you show at which border, which one you file taxes with, what happens with banking — has rules of its own.

This guide answers the question properly for Americans considering Colombian citizenship: the constitutional and legal answer, what the US side actually requires, the tax reality, the practical "two passports, now what?" mechanics, and the genuine risks to be aware of. It pairs naturally with the Colombian Citizenship Through Naturalization and Permanent Residency vs. Citizenship guides in this series.

This is general informational guidance, not legal or tax advice. Naturalization and US tax compliance are individually fact-specific. For an actual decision, work with a qualified Colombian immigration attorney and a US expat tax accountant.

The 30-Second Answer

Yes, Americans can hold US-Colombian dual citizenship, with the following key points:

• Colombia explicitly recognizes dual citizenship in Article 96 of its 1991 Constitution, and naturalized Colombians are not required to renounce their original citizenship.
• The United States legally recognizes dual nationality and does not require US citizens to choose. Naturalizing as a Colombian does not automatically cost you your US citizenship.
• You'll use your US passport for US borders and your Colombian passport for Colombian borders, and carry both when traveling between them.
• The catch is tax: US citizens remain US taxpayers for life, regardless of where they live or what other citizenships they hold. The US has no income tax treaty with Colombia, so cross-border tax planning matters more than usual.

The Colombian Side: It's Written into the Constitution

Colombia's position on dual citizenship is unusually clear and generous.

Article 96 of the 1991 Colombian Constitution explicitly recognizes that:

• Acquiring another nationality does not cause loss of Colombian citizenship.
• Colombians by birth can never be stripped of their nationality.
• Naturalized Colombians are not obligated to renounce their citizenship of origin.

In plain English: Colombia does not force you to choose. When you naturalize as a Colombian, you keep your American citizenship intact from Colombia's side. The same holds for Americans whose Colombian citizenship comes through descent or birth on Colombian soil — Colombia recognizes them as fully Colombian regardless of any other passport they hold.

This is reinforced by Ley 2332 de 2023, the current law governing acquisition, loss, and recovery of Colombian nationality (which replaced Ley 43 de 1993 effective September 25, 2023). Under that law, naturalization is a discretionary act of the state, but the dual-citizenship principle remains constitutional and is not waived in the naturalization process.

For Americans the practical path to Colombian citizenship is the M-visa → R-visa → naturalization sequence laid out in the Colombian Citizenship Through Naturalization guide. The short version: hold a qualifying M visa, then accumulate residency on the Resident (R) visa (5 years standard; 2 years if married to a Colombian, partnered, or with Colombian children), then apply for naturalization, pass the knowledge and (for non-native Spanish speakers) language exams, and take the oath. At no point in that process does Colombia ask you to give up your US passport.

The US Side: Legally Recognized, Not Officially "Promoted"

The US position on dual citizenship is more nuanced than Colombia's, but the bottom line is the same: it's allowed.

The US State Department officially recognizes that dual nationality exists. The State Department's guidance is explicit that US citizens may naturalize in another country, and doing so does not automatically cause loss of US citizenship — provided there is no intent to relinquish it. In fact, since a 1990 administrative policy change, the State Department has applied a strong presumption that a US citizen intends to retain their US citizenship when they naturalize elsewhere, take routine foreign oaths of allegiance, or accept non-policy-level foreign government employment.

That said, the US doesn't actively promote dual citizenship. A few practical wrinkles to know about:

• The naturalization oath in the other direction. When foreigners naturalize as US citizens, the Oath of Allegiance includes a renunciation clause. But in practice, the US doesn't enforce that renunciation against the other country, and most countries (Colombia included) don't recognize it. The result: most new US citizens keep their original citizenship in practice. This is the reverse of what most American-to-Colombian dual citizens face, but it shapes how the US system thinks about dual nationality.
• Loss of US citizenship requires intent. US citizenship is genuinely difficult to lose accidentally. You'd have to perform a "potentially expatriating act" (a defined list under US law) with the specific intention of giving up your US citizenship, and that intent has to be formally documented before a US consular officer. Simply naturalizing in Colombia and going on with your life does not meet that bar.
• Formal renunciation is a separate, deliberate process. If you actually wanted to give up US citizenship, you'd have to make a State Department appointment at a US consulate, sign formal renunciation paperwork, and (if you meet "covered expatriate" thresholds) potentially pay an exit tax under IRC Section 877A. This is not something that happens by accident.

Net-net: an American naturalizing as a Colombian, in the ordinary course, keeps both citizenships.

The Tax Reality: The Part Americans Underestimate

Here is the section that matters more than any other for Americans, and the one most "yes, dual citizenship is allowed" articles skip entirely.

US citizens are taxed on worldwide income for life, regardless of where they live or what other citizenship they hold. The United States is one of only a handful of countries in the world (along with Eritrea) that uses citizenship-based taxation. So becoming a Colombian citizen does not in any way reduce your US tax obligations: you still file an annual US return, you still report your global income, and you still face the IRS.

A few specific consequences a US-Colombia dual citizen needs to know:

You file in both countries if you're a Colombian tax resident. Colombia taxes residents on worldwide income once you cross 183 days of physical presence in any 365-day window (a rule that depends on where you live, not what passport you hold). At that point you're filing returns in both the US and Colombia.

Top Colombian rates are high. Colombia's top personal income tax rate is 39%, with non-residents on Colombian-source income facing a flat 35%. Dividends paid to non-resident foreign shareholders are subject to a 20% withholding, and standard VAT is 19%. So if you become a Colombian tax resident, you're not in a low-tax jurisdiction.

There is no US-Colombia income tax treaty. This is the single most consequential fact for US-Colombia dual citizens, and it surprises many of them. The two countries have never signed a comprehensive income tax treaty, so the standard "your tax treaty protects you" reasoning that works for US-Canada or US-UK dual citizens does not apply here. What protects US-Colombia dual citizens from double taxation are unilateral US tools:

• The Foreign Earned Income Exclusion (FEIE) — for the 2025 tax year filed in 2026, $130,000$USD per qualifying individual; for the 2026 tax year, $132,900$USD.
• The Foreign Tax Credit (FTC) — a dollar-for-dollar credit against US tax for income taxes paid to Colombia.
• These two tools together cover most cases reasonably well, but the math is more complicated than it would be under a treaty, and high-income or investment-heavy situations need real planning.

FBAR and FATCA filings are mandatory. Once you have Colombian bank accounts, you're typically also obligated to file:

• FBAR (FinCEN Form 114) — required when the aggregate value of your foreign accounts exceeds 10,000$USD at any point in the year.
• FATCA (Form 8938) — required when your foreign financial assets exceed expat thresholds (generally 200,000$USD for single filers abroad at year-end, 400,000$USD for married joint filers, with higher mid-year thresholds).

Penalties for missed FBAR and FATCA filings can be severe even if no tax is owed, which is why most US-Colombia dual citizens work with an accountant who specializes in expat returns.

Colombian banking can become harder. Because of FATCA, many foreign banks have reduced their willingness to serve US-person clients to avoid the compliance burden. Most Colombian banks still serve dual citizens, but expect more documentation than a non-American foreigner would face.

The bottom line on tax: dual citizenship is fully legal, but the cross-border tax compliance is real, ongoing work. Budget for an annual conversation with a US expat tax accountant who knows Colombia. The cost is typically a few hundred dollars; the cost of getting compliance wrong is much higher.

The Practical Mechanics: Two Passports, Two Borders, Two Lives

A few specific practical rules you'll live with as a US-Colombia dual citizen.

Use the right passport at the right border. By law, US citizens — including dual nationals — must enter and exit the United States on a US passport. You cannot use your Colombian passport at the US border. For Colombian borders, the standard practice is to use your Colombian passport for entering and leaving Colombia (which avoids any confusion in Migración records and means you don't need an entry stamp). So a typical international round trip looks like: US passport at US immigration, Colombian passport at Colombian immigration. Carry both passports when traveling between the two countries — the US Embassy in Bogotá specifically advises this.

Two valid passports, two renewal cycles. You'll need to keep both passports current. The US passport renews on its US cycle (typically 10 years for adults); the Colombian passport renews on its Colombian cycle. They're independent.

Your kids' situation. Children born to a US citizen abroad generally acquire US citizenship at birth (subject to specific physical-presence requirements for the US parent before the birth — confirm with a US immigration attorney), and children born in Colombia to Colombian parents are Colombian by birth. So children of a US-Colombia couple usually qualify for both citizenships from the start. They can also use both passports the same way: US passport for the US, Colombian passport for Colombia.

Voting rights. As a US citizen, you retain your right to vote in US elections (federal and, depending on state, state and local) — for which absentee voting is well-established. As a Colombian citizen, you gain the right to vote in Colombian elections, including at Colombian consulates abroad. Naturalized Colombian citizens face some narrow restrictions on holding certain public offices for a defined period after naturalization, but for voting rights and ordinary civic participation, you have both.

Consular protection has nuances. When you're in Colombia, you're a Colombian citizen in Colombia — meaning the US Embassy generally cannot intervene in Colombian government matters affecting you as a Colombian. (You retain access to US consular services for things like passport renewal, but the embassy can't override Colombian authorities acting toward you as a Colombian.) Similarly, when you're in the US, Colombian consulates serve you as a Colombian for Colombian-government purposes, but cannot shield you from US authorities acting toward you as an American. This rarely matters in practice, but it's the legal reality.

Compulsory service. Colombia has a libreta militar (military service obligation) for Colombian men in certain age brackets that can intersect with naturalization. In practice, reporting suggests the authorities have been relatively lenient with naturalized adult men on this point in recent years, but it remains a formal requirement. Confirm the current position with your immigration attorney at the time you apply.

When Dual Citizenship Doesn't Make Sense

Most Americans considering Colombian citizenship benefit from keeping both. But there are honest cases where the math doesn't work:

• You don't plan to live in Colombia long-term. If you'll spend less than ~183 days a year there, you generally won't trigger Colombian tax residency, and you may not need citizenship for the rights you actually use (most of which the R-visa permanent residency already provides). See Permanent Residency vs. Citizenship in Colombia for the side-by-side.
• You have a complex US tax situation already. High-income, business-owner, or investment-heavy Americans may find that adding a Colombian tax residency on top of existing US compliance creates more cost than benefit. Talk to a tax professional before naturalizing.
• You're already on a clear US-only path. If you're firmly anchored in the US and Colombia is a "maybe someday" backup, the costs of compliance may outweigh the benefits of dual status until your situation is clearer.

Common Misconceptions

"I'll lose my US citizenship if I naturalize as a Colombian." No. The US presumes you intend to retain US citizenship unless you affirmatively renounce it before a US consular officer.

"Colombia will make me renounce my US citizenship." No. Article 96 of the Colombian Constitution and Ley 2332 de 2023 explicitly do not require renunciation.

"My US-Colombia tax bill will be sky-high." Usually not, if you use the FEIE and FTC properly. But the absence of a tax treaty means the situation needs real planning, especially for investment income, dividends, and pensions.

"I can just use whichever passport at any border." No. US citizens must enter and exit the US on a US passport, period.

"Renouncing US citizenship to escape tax is easy." It's deliberately not easy. Formal renunciation requires a consular appointment and a fee, and high-net-worth or high-tax-history "covered expatriates" face the Section 877A exit tax. This is a major decision with permanent consequences, not a casual tax-planning move.

"Colombian citizenship is faster if I marry a Colombian." It's faster, not automatic. Marriage shortens the residency clock (2 years on the R visa instead of 5), but you still go through the full naturalization process, including the exam.

Quick Checklist

1. Yes, US-Colombia dual citizenship is fully legal and is supported by both Article 96 of the Colombian Constitution and US State Department recognition of dual nationality.
2. Colombia does not require naturalized citizens to renounce their US citizenship.
3. The US does not strip you of citizenship for naturalizing in Colombia, absent specific intent to renounce.
4. Use the US passport at US borders, the Colombian passport at Colombian borders, and carry both when traveling between them.
5. US citizens are taxed on worldwide income for life regardless of dual status — citizenship-based taxation does not change.
6. There is no US-Colombia income tax treaty. Protection from double taxation comes from the FEIE (132,900$USD for 2026) and the Foreign Tax Credit, not from a treaty.
7. Colombian tax residency triggers at 183 days of physical presence; the top personal rate is 39%.
8. FBAR (foreign account aggregate > 10,000$USD) and FATCA (Form 8938) are mandatory annual filings for most US-Colombia dual citizens.
9. Children of US-Colombia couples can generally hold both citizenships from birth.
10. Work with a US expat tax accountant familiar with Colombia, the absence of a tax treaty makes this more important than usual.
11. Colombian citizenship is not automatic — it requires the M-visa → R-visa → naturalization path under Ley 2332 de 2023.

Final Thoughts

For an American genuinely building a life in Colombia, dual citizenship is one of the better legal outcomes you can reach. It cements your status in Colombia in a way no visa can, lets you vote and fully participate in Colombian civic life, gives you a passport with strong visa-free access (commonly cited as 130-plus countries including the Schengen Area), and — because both countries permit it — costs you nothing on the US side. The legal door is genuinely open.

The thing that takes the most work isn't the legal question. It's the ongoing tax compliance: filing in both countries, navigating the absence of a tax treaty, keeping FBAR and FATCA current. None of it is unmanageable, but it's real work, and it's the reason "yes you can" should always come with "and here's what to plan for."

If Colombia is a long-term home and you're committed to the path, treat dual citizenship as the natural endgame: build toward it deliberately through the visa stages, keep your US tax compliance clean from the start, line up an expat tax accountant who knows both countries, and at the end of the path you get the best of both: an American identity that doesn't go away, and a Colombian identity that makes your new home permanent.
