Does US Allow Dual Citizenship? A Complete Guide for Americans in 2025

For U.S. citizens considering dual citizenship, the perks are hard to ignore: visa-free travel, global business flexibility, and a legal fallback abroad. But beneath the surface lies a maze of tax obligations, legal limitations, and potential conflicts between countries.

One of the most common questions is: Does US allow dual citizenship?
Yes, the United States does permit dual citizenship, but it comes with strings attached. The U.S. won’t make you renounce your citizenship if you acquire another, but you’re still bound by American tax laws, military draft policies, and passport rules—no matter where you live.

From FATCA filings and FBAR reporting to restrictions on federal employment and limited consular protection overseas, holding dual nationality can sometimes feel more like a burden than a benefit—especially if you’re not prepared.

We will break down how U.S. law treats dual citizenship, the hidden risks most Americans overlook, and how to navigate the process legally and strategically.

Common Concerns We Address

• Will obtaining another passport make me lose U.S. citizenship?
• Can my U.S. citizen child travel using only a foreign passport?
• Which countries allow dual citizenship with the U.S.?
• How do taxes and military service work for dual nationals?
• What happens if I hold U.S. and foreign nationality but live abroad?

If you are considering applying for a second citizenship, or already hold it, this guide will help you understand your position, make informed decisions, and remain compliant with both U.S. and foreign laws.

What Is Dual Citizenship and How Does It Work?

Definition of Dual Citizenship vs. Second Citizenship

Dual citizenship (also referred to as dual nationality) means that a person is legally recognized as a citizen of two countries at the same time. Dual citizens hold the rights, responsibilities, and protections of both nations and are often allowed to hold two valid passports.

Second citizenship, in contrast, typically refers to holding a second nationality that may not be fully recognized or supported by the original country. For example, some nations automatically revoke citizenship if a citizen voluntarily acquires a second one, making it effectively a second but not a dual citizenship.

Multiple Citizenship vs. Permanent Residency: What’s the Difference?

Dual citizenship provides broader legal standing and benefits than permanent residency, but also comes with increased responsibility and complexity, especially in legal and tax matters.

Legal Status and Rights Under Dual Citizenship

• Freedom of Movement: Travel freely between both countries using respective passports.
• Work & Residency: Eligible to live and work without a visa in either country.
• Legal Obligations: Must comply with both nations’ laws, including taxation and military service.
• Protection Abroad: Access to consular services may be limited in your second country of nationality.
• U.S. Passport Use: All U.S. citizens—including dual nationals are legally required to enter and exit the U.S. using a valid U.S. passport.

Does the United States Allow Dual Citizenship?

The U.S. Government’s Stance on Dual Nationality

The United States allows dual citizenship under current law. There is no statute in the Immigration and Nationality Act (INA) that explicitly prohibits holding citizenship in another country while being a U.S. citizen. In fact, Section 101(a)(22) of the INA simply defines a U.S. national as someone who either:

• Is a U.S. citizen, or
• Owes permanent allegiance to the United States (e.g., persons born in American Samoa)

This legal framework makes it clear that U.S. citizens may acquire foreign nationality by birth, descent, naturalization, or citizenship by investment without having to renounce their American citizenship, provided they do not do so with the intention of giving it up.

The U.S. Supreme Court has consistently supported this stance. In Kawakita v. United States (1952), the Court stated:

“A person may have and exercise rights of nationality in two countries and be subject to the responsibilities of both.”

This means dual citizens are legally recognized and protected, but also expected to follow the laws of both nations.

Oath of Allegiance and Renunciation Myths Explained

One of the most misunderstood elements in the citizenship process is the Oath of Allegiance, which all naturalized U.S. citizens must take. The oath includes a clause about renouncing “all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty.”

However, this language is symbolic and ceremonial, not a legally binding act of renunciation under international law. U.S. immigration authorities do not enforce this clause by requiring proof of renunciation of your former citizenship. Many naturalized citizens retain their original nationality unless their home country requires otherwise.

To actually lose U.S. citizenship, a person must:

• Voluntarily perform an expatriating act (such as foreign naturalization), and
• Do so with the intention of giving up their U.S. citizenship

Unless both are clearly proven, U.S. citizenship remains intact.

Common Misunderstandings About U.S. Dual Citizenship Policy

Misconception 1: You automatically lose U.S. citizenship if you get another passport.
→ False. You only risk losing it if you explicitly intend to relinquish your U.S. citizenship during the process.

Misconception 2: You cannot work for the U.S. government if you have dual nationality.
→ Partially true. Dual citizenship may affect eligibility for certain security clearance-required roles, but many public positions remain open to dual citizens.

Misconception 3: My child can enter the U.S. with a foreign passport.
→ False. By law, all U.S. citizens, including children, must enter and exit the United States using a valid U.S. passport. They are not eligible for a U.S. visa under any circumstances.

Misconception 4: Dual citizens are fully protected by the U.S. in their other country of nationality.
→ Not always. The U.S. may have limited ability to assist dual nationals if they are present in the country of their other nationality.

Benefits of Holding U.S. Dual Citizenship

Benefits for Travel, Work, and Global Mobility

Holding dual citizenship with the United States can open up significant advantages, especially for those engaged in international business, frequent travel, or family reunification abroad. Key Benefits of Dual Citizenship:

1. Expanded Travel Freedom: Dual citizenship often provides access to a broader range of visa-free or visa-on-arrival countries via the second passport. This can streamline global travel, reduce visa-related delays, and lower associated costs.

2. Right to Live and Work in Two Countries: Dual citizens generally enjoy full residency, employment, healthcare, and property ownership rights in both countries. This opens the door to broader job markets and lifestyle options without the need for lengthy visa applications or work permits.

3. Educational Access and Cost Savings: Dual citizens may qualify for domestic tuition rates, government-funded scholarships, and simplified admission processes at institutions in both countries—offering significant educational and financial advantages.

4. Easier Family Sponsorship: U.S. citizens can already sponsor immediate relatives for permanent residency. A second nationality may allow individuals to sponsor other family members more easily under different immigration systems, supporting broader family reunification.

5. Strategic Business Expansion: For entrepreneurs and investors, dual citizenship can unlock access to foreign markets, streamline the process of registering international businesses, and provide more favorable tax treatment or regulatory frameworks abroad.

These benefits are particularly attractive for U.S. citizens working remotely, planning for retirement abroad, or managing international investments.

Rights and Responsibilities of American Dual Citizens

While dual citizenship expands your freedoms, it also carries additional legal and civic duties in both nations.

Rights as a U.S. Dual Citizen:

• Vote in all U.S. elections
• Hold a U.S. passport and travel freely in/out of the U.S.
• Access federal benefits and protections
• Petition for family immigration
• Apply for public office (with some security clearance exceptions)

Responsibilities of Dual U.S. Citizens:

• Use a U.S. Passport to enter or leave the United States (mandatory under U.S. law)
• File U.S. Taxes annually, regardless of residence
• Register for Selective Service (males age 18–25)
• Serve on a jury if summoned
• Comply with the laws of both countries, including military service if applicable

These responsibilities may overlap or conflict with the obligations of your other nationality, which is why legal and tax planning is often essential for dual nationals.

Potential Drawbacks: Taxes, Military Service, and Legal Conflicts

A second passport may offer freedom and flexibility—but it also comes with strings attached. Many dual citizens are caught off guard by hidden obligations that can affect their taxes, legal standing, and even career options. Before securing dual nationality, it’s critical to understand the potential downsides that come with holding two allegiances.

1) U.S. Global Taxation

The United States is one of the few countries that impose taxes based on citizenship, not residence. As a result:

• You must file U.S. tax returns every year, even if you live abroad.
• You may owe taxes on foreign-earned income, unless tax treaties or IRS exclusions apply.
• Reporting requirements (e.g., FBAR, FATCA) apply to foreign bank accounts.

2) Military Service

If your second country mandates compulsory military service, you may be required to serve, regardless of U.S. citizenship. In some countries, this applies immediately upon entry, or upon reaching adulthood.

3) Legal Conflicts and Limited U.S. Protection

When a dual national is in the territory of their second country, U.S. consular protection may be limited or denied altogether. In addition:

• You may face exit bans, legal proceedings, or travel restrictions.
• You must obey local laws, which may differ significantly from U.S. norms.

4) Restricted Job Access

Some sensitive government jobs in the U.S. may be off-limits to dual nationals, especially if they require a high-level security clearance.

How to Obtain Dual Citizenship in the USA

The path to becoming a U.S. dual citizen varies depending on how you acquire your second nationality. The U.S. government does not offer a special “dual citizenship” application. Instead, you become a dual citizen when you legally acquire a second nationality while retaining your U.S. citizenship, or vice versa.

Citizenship By Birth (Jus Soli and Jus Sanguinis Explained)

There are two primary legal principles by which citizenship can be granted at birth:

• Jus Soli (Right of the Soil): If you are born on U.S. soil, you are automatically a U.S. citizen—even if your parents are foreign nationals.
• Jus Sanguinis (Right of Blood): If you are born abroad to U.S. citizen parents, you may automatically acquire U.S. citizenship under certain conditions.

You can also be a dual citizen at birth if:

• You are born in the U.S. to parents from another country (you acquire U.S. citizenship by birth and potentially your parents’ nationality by descent).
• You are born abroad to one or two U.S. citizen parents, and the other country grants citizenship by place of birth.

Example: A child born in Germany to a U.S. mother and a German father may be a dual citizen of both countries from birth.

Citizenship by Naturalization

Foreign nationals who legally reside in the United States—usually on a green card—can become U.S. citizens through the naturalization process, without being required by U.S. law to renounce their original citizenship.

Eligibility for U.S. Naturalization Includes:

• Having a green card (lawful permanent residency)
• Living in the U.S. for at least 3–5 years (depending on circumstances)
• Demonstrating good moral character
• Passing English and civics tests
• Taking the Oath of Allegiance (which does not invalidate your original citizenship unless your country requires renunciation)

Important: The U.S. permits dual nationality, but your original country must also allow it. Some countries—like Japan, China, and India—do not.

Citizenship By Marriage to a Foreign National

If you are a U.S. citizen married to a foreign national, your spouse may be eligible for U.S. citizenship after obtaining a green card and living with you in the U.S. for three years.

Likewise, if you marry a citizen of another country that permits spousal naturalization, you may be able to apply for their nationality without giving up your U.S. citizenship.

Example: Spain allows U.S. citizens to apply for Spanish nationality after one year of marriage to a Spanish citizen and residence in Spain.

Via Citizenship-by-Investment Programs

Some countries grant citizenship in exchange for an investment in real estate, bonds, or national development funds.

This route does not exist in the U.S., but many Americans seek second citizenship by investment programs in countries such as:

• Turkey Citizenship by Investment
• Saint Kitts and Nevis Citizenship by Investment
• Dominica Citizenship by Investment
• Malta Citizenship by Investment
• Portugal citizenship by Investment (via Golden Visa, then naturalization) 

Such programs may offer faster processing and don’t require residency in the country.

Fast-Track Options for U.S. Expats and Retirees

Several countries offer simplified paths to dual citizenship for Americans, particularly retirees or long-term residents.

Top examples include:

• Argentina – Just 2 years of legal residence
• Paraguay – Citizenship possible after 3 years
• Portugal – Citizenship after 5 years, no language test for Brazilian nationals
• Italy or Ireland – If eligible through ancestry

These countries are popular among U.S. citizens seeking a tax-favorable, travel-friendly second citizenship.

Full List of Countries with Dual Nationality Restrictions

Below is a list of countries that generally do not allow dual citizenship or impose strict limitations:

*Note: Laws in some countries are subject to change. Always confirm with your country’s embassy or consulate before applying for another citizenship.

What Happens If You Hold U.S. Citizenship and Apply Anyway?

If your home country does not allow dual citizenship, you may face the following consequences when naturalizing in the U.S.:

• Automatic Revocation: Your original citizenship may be revoked as soon as your U.S. naturalization is approved.
• Renunciation Requirement: Some countries will require you to submit a formal renunciation letter or visit a consulate to surrender your original nationality.
• Loss of Benefits: You may lose the right to vote, own property, inherit assets, or participate in national health or pension schemes.
• Reentry Restrictions: If citizenship is revoked, you may need a visa to visit your birth country in the future.

Important: These laws are country-specific. Always consult with an immigration attorney or embassy representative to avoid accidental loss of rights or travel restrictions.

Taxes and Dual Citizenship: What You Must Know

One of the most pressing concerns for U.S. citizens holding another nationality is taxation. Unlike most countries, the United States uses citizenship-based taxation—which means that U.S. citizens must file tax returns regardless of where they live or where their income is earned.

Where Do U.S. Dual Citizens Pay Taxes?

As a dual citizen, you are required to:

• File a U.S. tax return annually, even if you live abroad
• Report worldwide income, including foreign salary, property income, dividends, or capital gains
• Disclose foreign bank accounts and assets via FBAR (FinCEN Form 114) and FATCA (Form 8938)

Even if you pay taxes in your second country of citizenship, you may still owe U.S. taxes—unless certain credits or exclusions apply.

Example: A U.S. citizen living and working in Germany must still file a U.S. tax return each year—even if fully taxed in Germany.

How to Avoid Double Taxation If No Treaty Exists

Fortunately, the IRS provides several options for dual citizens to reduce or eliminate double taxation.

Foreign Earned Income Exclusion (FEIE)

This allows U.S. citizens living abroad to exclude foreign salary or earned income from U.S. taxable income.

Key points:

• You must pass the Physical Presence Test (330 days abroad in a 12-month period) or Bona Fide Residence Test (entire tax year abroad)
• The maximum exclusion is $130,000 per person for 2025
• If you’re married and both spouses work abroad, each may claim the exclusion

Foreign Tax Credit (FTC)

If you pay income taxes to another country, you may claim a dollar-for-dollar credit against U.S. taxes owed.

Key points:

• Cannot be claimed for income excluded under FEIE
• Can be more advantageous for high-income earners
• Reduces or eliminates U.S. tax liability on foreign income

Foreign Housing Deduction

This provision allows you to deduct qualified housing expenses while living abroad, such as:

• Rent
• Utilities (excluding phone and internet)
• Security expenses

Limits apply depending on the city and country you live in. The maximum is typically around 16% of the FEIE limit—approximately $1,650 per month.

Important Note: Even if you owe no tax, you must still file. Failure to do so can lead to:

• Penalties
• Loss of exclusions/credits
• Increased audit risk
• Revocation of passport (in rare cases, due to unpaid tax debt)

Pro tip: Always consult a tax advisor experienced in expat taxation to navigate these requirements and avoid costly mistakes.

Documents Required for Dual Citizenship Application

While the United States does not require a separate application for dual citizenship, individuals seeking to obtain or maintain a second nationality—either through naturalization abroad or applying for U.S. citizenship while retaining their original nationality—must provide supporting documentation. The exact requirements depend on your method of acquiring the second citizenship and the country involved.

Birth and Marriage Certificates

Proof of lineage or family connection is crucial in many countries that grant citizenship by descent or marriage.

You may need:

• A certified birth certificate
• A long-form birth certificate showing parental details
• Your parents’ or grandparents’ birth or naturalization records (for citizenship by ancestry)
• A legal marriage certificate, if applying through a spouse’s nationality

In some countries, all documents must be:

• Notarized
• Apostilled (via the Hague Convention)
• Officially translated into the destination country’s language

Proof of Residence and Identity

If you are applying for U.S. naturalization or a second nationality based on residency, expect to provide:

• Green card or permanent residency proof (Form I-551 for the U.S.)
• Passport copies (U.S. and foreign)
• Social Security Number (SSN) if residing in the U.S.
• Utility bills, lease agreements, or tax returns to prove continuous residence
• Police clearance or FBI background check (required by some countries)

For example:

• In Portugal, you’ll need to provide proof of 5 years of legal residence
• In Italy, those applying via ancestry may need to prove unbroken citizenship transmission

Country-Specific Requirements

Each country has its own legal and administrative procedures. Some examples:

• Spain: Must declare intent to retain Spanish nationality after acquiring U.S. citizenship.
• India: Does not permit dual nationality; instead offers OCI (Overseas Citizen of India) status.
• Canada: No special documents required—dual citizenship is automatically accepted.

Checklist for Applicants:

• Valid passports (U.S. and foreign)
• Government-issued ID cards (where applicable)
• Immigration records (U.S. Form I-94, visa records, or local equivalents)
• Tax records or proof of employment (especially for economic citizenship)
• Passport-sized photographs (per target country specs)

Always consult with the relevant embassy or consulate for exact instructions. Missing or incorrectly formatted documents may delay or void your application.

• Asset Diversification: Protect your financial holdings with access to offshore banking and legal tax residency
• Emergency Exit Strategy: Secure a backup option in case of instability or healthcare crises
• Education Access: Qualify for in-country tuition fees and government-subsidized education in countries like Germany, France, or Canada

Frequently Asked Questions

Can You Have Dual Passports?

Yes. If both the United States and your second country of citizenship allow dual nationality, you are permitted to hold two valid passports. Each passport must be used according to the entry and exit laws of the country you’re visiting.

For example, a U.S.–Canada dual citizen should enter and exit the U.S. using a U.S. passport and Canada using a Canadian passport.

How Many Passports Can a U.S. Citizen Have?

Legally, there is no limit to the number of citizenships or passports a U.S. citizen can hold, as long as each additional country permits it. The U.S. government only mandates that its citizens enter and exit the United States using a U.S. passport.

Multiple passports may help in:

• Visa-free travel to restricted countries
• Avoiding political restrictions
• Establishing residency, education, or property ownership abroad

What Countries Allow Dual Citizenship for U.S. Citizens?

Many countries allow dual citizenship with the U.S., including:

• European countries: United Kingdom, France, Germany, Ireland, Italy, Portugal
• Americas: Canada, Brazil, Argentina, Dominican Republic
• Asia: South Korea, Philippines, Turkey, Israel
• Africa: Nigeria, South Africa, Egypt
• Oceania: Australia, New Zealand

Note: Countries like India, Japan, and China do not allow dual nationality. You may automatically lose their citizenship upon naturalizing in the U.S.

Easiest Country to Get Citizenship as an American

Some countries offer fast-track naturalization or ancestry-based citizenship that make the process easier for U.S. citizens.

Top choices:

• Argentina – 2 years of residence; no language test
• Ireland – Citizenship by descent if you have Irish grandparents
• Italy – Citizenship through ancestry with no generational limits (if uninterrupted)
• Dominica citizenship by investment or Saint Lucia citizenship by investment – Citizenship-by-investment starting at $130,000
• Portugal – 5 years of residence required; known for Golden Visa program

Will I Have to Renounce My U.S. Citizenship?

No, U.S. law does not require you to give up your American citizenship when acquiring another. You would only lose U.S. citizenship if you:

1. Voluntarily apply for foreign citizenship,
2. Clearly intend to relinquish U.S. citizenship, and
3. Declare that intention to a U.S. consulate or embassy.

If these conditions are not met, your U.S. citizenship remains intact—even if your second country does not recognize it.

Can I Travel Without My U.S. Passport?

No. If you are a U.S. citizen, including a dual national, you must use a valid U.S. passport to enter and leave the United States—even if you have another valid passport. This is a legal requirement under U.S. immigration law (8 U.S.C. § 1185).

Traveling without a U.S. passport may:

• Lead to entry delays
• Result in the denial of boarding
• Violate federal travel regulations

If your U.S. passport has expired, renew it before traveling internationally.

Conclusion

The United States does allow dual citizenship, but the real key lies in whether your second country does too. For Americans, holding a second passport can unlock a world of freedom, flexibility, and financial opportunity—but only if approached strategically.

From taxes and travel to legal protection and property ownership, dual citizenship is a powerful tool when planned correctly. Whether you’re applying through ancestry, marriage, investment, or residence, it’s critical to understand your obligations—and your rights.
