What Is Dual Citizenship?

Dual citizenship means you’re legally recognized as a citizen by two or more countries at the same time. It gives you the right to hold multiple valid passports, enjoy residency rights in both nations, and benefit from visa-free travel — if the countries involved recognize your dual status.

⚠️ Not all countries allow dual citizenship. Some, like China or India, require you to give up your original citizenship if you acquire another.

Dual vs. Second Citizenship: What’s the Difference?

• Dual citizenship means mutual legal recognition between countries. You don’t have to renounce your original nationality.

• Second citizenship may simply mean holding two passports — but one or both countries don’t formally recognize the dual status. This can affect taxes, military obligations, or consular protection.

✅ Example: The U.S. allows dual citizenship. But Singapore, Japan, and Saudi Arabia may revoke your original citizenship if you acquire citizenship in another country.

Can You Hold More Than Two Passports?

Yes — if all involved countries allow it. This is referred to as multiple citizenship, and it’s legal in many places.

Dual vs Multiple Citizenship: Can you be a Citizen in Multiple Countries?

Another common question: Can you be a citizen in multiple countries? The answer is yes—if the laws of all countries involved allow it. Dual citizenship refers to two nationalities. Multiple citizenship means holding three or more.

While it’s rare, some individuals can hold 4 or more passports, typically through birth, descent, and investment combined.

How to Get Dual Citizenship in 2025: 3 Legal Paths to Become a Dual Citizen

There are multiple ways to acquire a second citizenship depending on your origin, circumstances, or financial capability. Here’s how most people gain dual or multiple citizenship legally:

You can get dual citizenship through descent (ancestry), investment, or naturalization—each with different eligibility requirements and timelines.

Here’s how each route works:

1- Citizenship By Investment (Fast-Track Dual Citizenship Programs)

Ideal for high-net-worth individuals who want a second passport without residency.

These programs legally grant citizenship by investment (CBI) in exchange for a donation, property purchase, or government bond. Popular CBI countries in 2025:

💡 These programs are legal and government-approved. You retain your original citizenship if your home country permits dual nationality.

• Timeline: 3–12 months
• Cost: $100,000+

2. By Naturalization (Residency + Application)

Standard path for expats, spouses, or long-term residents.

Naturalization usually requires you to live in the country for several years, pass a language or civics test, and renounce your original citizenship—unless dual citizenship is allowed.

Examples:

• Portugal: 5 years of residency (no requirement to live full-time)

• Spain: 10 years (2 for Latin Americans)

• Mexico: 5 years (or 2 years through marriage or descent)

🔁 U.S. citizens applying in Mexico can keep their US citizenship, as both countries recognize dual nationality.

• Timeline: 2–10 years
• Cost: Low to moderate

3. Citizenship By Descent (Citizenship Through Parents or Grandparents)

Fastest and cheapest way—if you’re eligible.

Many countries automatically grant citizenship by descent to those with parents or grandparents from that country. This process is often easier than naturalization.

✅ Countries with Strong Descent Laws:

• Italy: No generation limit (as long as records are intact)

• Ireland: Through parents or grandparents

• Poland, Hungary, Germany: Citizenship through ancestry available

• Mexico: If one or both parents are Mexican-born, you can reclaim citizenship

🧾 Example: A U.S. citizen with a Mexican parent can apply at a Mexican consulate using proof of birth and lineage to obtain dual citizenship.

• Timeline: 3–12 months
• Cost: Usually minimal (document fees only)

Does the U.S. Allow Dual Citizenship?

Yes, the United States allows dual and even multiple citizenships.
Americans can legally acquire another nationality without giving up their U.S. citizenship. However, U.S. citizens must:

• Use their U.S. passport to enter and exit the U.S.

• Comply with all U.S. laws, including worldwide tax reporting

• Ensure the other country also allows dual citizenship to avoid renunciation risks

There’s no legal cap on how many nationalities a U.S. citizen can hold—so long as each country involved accepts it.

And a common question is: “How many citizenships can you have in the U.S.?”

There’s no official limit on how many citizenships a U.S. citizen can hold. As long as the other countries involved also permit dual or multiple citizenship, an American may legally maintain three, four, or more nationalities at once.

For example, someone could:

• Be born a U.S. citizen

• Inherit Italian citizenship through ancestry

• Acquire St. Kitts citizenship by investment

• Naturalize in Canada after residency

That individual would legally hold four passports—provided none of the involved countries require renunciation.

Can You Regain Citizenship After Giving It Up?

In some cases, yes—especially if:

• You were born in the country

• Your parents are citizens

• You meet special return criteria (e.g., Germany, India via OCI)

But in others, renunciation is permanent and hard to reverse.

Do You Have to Pay Taxes in Both Countries With Dual Citizenship?

Yes — if you’re a U.S. citizen, you must file taxes on global income, even if you live abroad. Most dual citizens are required to file tax returns in both countries, but that doesn’t necessarily mean they’ll owe taxes to both.

U.S. Dual Citizens: Global Tax Responsibilities

The U.S. is one of the few countries that uses citizenship-based taxation. That means:

• You must file a U.S. tax return every year—no matter where you live.

• You may owe U.S. taxes on your global income, even if taxed elsewhere.

How to Avoid Double Taxation

Dual citizens can legally reduce their U.S. tax burden using:

• Foreign Earned Income Exclusion (FEIE) – Excludes up to ~$120,000 of foreign income

• Foreign Tax Credit (FTC) – Credits for taxes paid to another country

• Foreign Housing Exclusion – Deducts qualifying housing costs abroad

To qualify, you must pass either:

• The Bona Fide Residence Test, or

• The Physical Presence Test

Tip: Always consult an international tax expert before applying for dual citizenship or investing overseas. Penalties for misfiling are severe.

What Legal Duties Come With Dual Citizenship?

Dual nationals must obey the laws of both countries even when those laws overlap or conflict.

Here are the most common legal obligations:

Military Service

Some countries require mandatory military service, even for dual nationals:

• South Korea (especially males aged 18–35)

• Israel

• Greece

Jury Duty and Civic Participation

You may also be called to:

• Serve on a jury

• Vote in local elections

• Participate in political or community service

Asset and Tax Reporting

If you hold foreign bank accounts or assets:

• U.S. citizens must report under FATCA and FBAR rules

• Other countries may require disclosure of offshore income or inheritance

⚠️ Failure to comply can lead to fines, legal charges, or passport revocation. Know your obligations before obtaining a second citizenship.

3 Major Risks of Dual Citizenship You Should Know

1. Conflicting Laws

You may face clashing laws between two governments:

• Double taxation

• Conflicting military service expectations

• Property ownership restrictions

2. Limited Consular Protection

When you’re in one of your home countries, your second country usually cannot intervene. That means:

• No diplomatic help during legal trouble

• Local laws take precedence—even if they conflict with your other citizenship

3. Travel Restrictions and Passport Conflicts

Dual citizens may face:

• Difficulty entering countries that don’t recognize the other citizenship

• Border delays or passport confiscation

• Entry bans in politically sensitive regions

Before traveling, always:

• Use the passport of the country you’re entering

• Review exit/entry rules for both nationalities

🇪🇺 Can EU Citizens Hold Dual Citizenship?

Yes—but the rules vary. Some EU countries fully allow it, while others only permit it under strict conditions.

Tip: Citizenship through Malta or Cyprus offers full EU rights and is the most investment-friendly.

Can You Hold Three or More Citizenships?

Yes, you can have 3 or more nationalities—

The number of citizenships you can hold depends on each country’s laws—some permit multiple or even triple citizenships, while others impose strict limitations.

There’s no international law limiting the number of passports you can hold.

Examples:

• Someone born in the USA to an Italian and Israeli parent may hold all three.

• Investors may gain additional passports through citizenship by investment without losing their original one.

Combine ancestry, naturalization, and investment routes to build your passport portfolio—legally.
