Nigerian Dual Citizenship: Complete 2026 Guide for Nigerians in the Diaspora

Nigerian dual citizenship is an important topic for Nigerians living abroad who have acquired, or are considering acquiring, citizenship in another country. Whether you live in the United Kingdom, United States, Canada, South Africa, Australia, or elsewhere, understanding Nigerian dual citizenship laws can help you protect your rights, manage your Nigerian passport, maintain your identity documents, and stay connected to Nigeria.

For many Nigerians in the diaspora, becoming a citizen of another country does not necessarily mean giving up Nigerian citizenship. However, the rules depend on how you became a Nigerian citizen and the laws of the other country.

This 2026 Nigerian dual citizenship guide explains the legal framework, passport rules, children born abroad, NIN requirements, travel, taxes, property, name changes, and other important issues Nigerians abroad should understand.

Does Nigeria Allow Dual Citizenship?

Yes, Nigeria allows dual citizenship in certain circumstances.

Under the 1999 Constitution of the Federal Republic of Nigeria, Nigerian citizens by birth can acquire the citizenship of another country without automatically losing their Nigerian citizenship.

This means a Nigerian citizen by birth may become a British, American, Canadian, Australian, or other foreign citizen while retaining Nigerian citizenship, provided the laws of the other country also permit dual or multiple citizenship.

This is the foundation of Nigerian dual citizenship for millions of Nigerians living outside the country.

Who Can Have Nigerian Dual Citizenship?

The constitutional rules are particularly important for people who are Nigerian citizens by birth.

Nigeria’s citizenship framework distinguishes between citizenship acquired by:

• Birth
• Registration
• Naturalisation

If you became a Nigerian citizen through registration or naturalisation rather than by birth, different rules may apply.

Therefore, before acquiring another nationality, it is important to understand the legal basis on which you hold Nigerian citizenship.

Nigerian Dual Citizenship and Multiple Nationalities

Can a Nigerian have three citizenships?

Potentially, yes. A Nigerian citizen by birth may retain Nigerian citizenship while holding citizenship in two or more other countries, depending on the laws of those countries.

For example, someone could potentially hold:

• Nigerian citizenship
• British citizenship
• Canadian citizenship

However, Nigerian law is only one part of the picture. Each additional country has its own rules regarding multiple citizenship. Before applying for another nationality, check the citizenship laws of every country involved.

Nigerian Dual Citizenship: How Other Countries Treat It

Although Nigerian dual citizenship is recognised under Nigerian law in relevant circumstances, other countries may have very different rules. Some countries allow multiple citizenship freely, while others impose restrictions.

Your second country may have requirements concerning:

• Passport use
• Entry and exit
• Military service
• Taxes
• Political rights
• Disclosure of other citizenships
• Retention of citizenship

Understanding both Nigerian law and the law of your other country is essential.

Nigerian Dual Citizenship in the UK and Canada

The United Kingdom and Canada generally permit dual or multiple citizenship. This means eligible Nigerians who become British or Canadian citizens can generally retain their Nigerian citizenship if they are Nigerian citizens by birth.

If you are relocating to North America, you can learn how to relocate to Canada via the Express Entry route. For active community support, check out the top Facebook groups for Nigerians living in Canada and the UK.

However, Nigerian dual citizens should still understand the passport and immigration requirements of both countries. Keep your passports valid and check the latest rules before travelling.

Nigerian Dual Citizenship and the United States

The United States recognises dual nationality.

However, American citizens, including people with Nigerian dual citizenship, are generally required to enter and leave the United States using a valid U.S. passport. A U.S. citizen cannot simply use a Nigerian passport as a substitute for a U.S. passport when entering or leaving the United States.

U.S. citizens are also not eligible to apply for a U.S. visa as an alternative to travelling as a U.S. citizen. If you have Nigerian dual citizenship and U.S. citizenship, it is important to understand the passport rules before travelling.

For official information, read the U.S. Department of State guidance on dual nationality.

Nigerian Dual Citizenship and South Africa

South Africa has also experienced important legal developments relating to dual citizenship.

In 2025, South Africa’s Constitutional Court ruled on provisions relating to the automatic loss of South African citizenship after acquiring another nationality without prior permission.

Because South African citizenship law and administrative procedures can change, Nigerians living in or connected to South Africa should confirm the latest requirements with South African authorities before acquiring another nationality. The important lesson for Nigerians with Nigerian dual citizenship is simple: never assume that the rules of one country automatically apply to another.

Which Passport Should a Nigerian Dual Citizen Use?

One of the most common questions about Nigerian dual citizenship is which passport to use when travelling. There is no single rule that applies to every country; the correct passport depends on the laws of the country you are entering or leaving.

For example, a Nigerian-American dual citizen should generally use a U.S. passport when entering and leaving the United States. For official U.S. guidance, see the U.S. Department of State’s information on dual nationality.

Can a Nigerian Dual Citizen Travel to Nigeria With a Nigerian Passport?

Yes, maintaining a valid Nigerian passport is important for Nigerians living abroad. For people with Nigerian dual citizenship, a valid Nigerian passport provides evidence of Nigerian citizenship when travelling internationally.

Before travelling to Nigeria, check that:

• Your Nigerian passport is valid.
• Your personal details are correct.
• Your NIN information is accurate.
• Your passport name matches your supporting documents.
• Your children have the necessary travel documents.

What If Your Nigerian Passport Has Expired?

Having Nigerian dual citizenship does not mean your Nigerian passport remains valid indefinitely. A passport has its own validity period and must be renewed or reissued when necessary.

If your Nigerian passport has expired:

1. Check current renewal requirements.
2. Confirm whether you are eligible for online or contactless services.
3. Contact the nearest Nigerian Embassy, High Commission, or Consulate if necessary.
4. Check your airline and transit-country requirements before travelling.

Use official channels for passport services. In Europe, be mindful of bureaucratic delays—such as the embassy trap in Italy—and do not rely on unofficial agents who promise guaranteed passport approval.

Nigerian Dual Citizenship and NIN Requirements

The National Identification Number (NIN) is an important identity requirement for Nigerians. For Nigerians abroad, maintaining accurate NIN information is particularly important when dealing with Nigerian passport services.

If you live outside Nigeria and need NIN services, see our complete guide on BVN and NIN in the diaspora for Nigerians: how to register and update your details. Always use approved enrolment channels provided by the National Identity Management Commission (NIMC).

Nigerian Dual Citizenship and Contactless Passport Services

The Nigeria Immigration Service has introduced contactless and digital passport services intended to make passport applications more convenient for eligible Nigerians living abroad. This system is particularly relevant to Nigerian dual citizens who live far from Nigerian embassies or consulates.

To use this feature, follow our guide on 5 easy steps to use the new Nigerian contactless passport system before submitting your application.

Nigerian Dual Citizenship and Data Harmonisation

Keeping your information consistent across all documents is extremely important. A Nigerian living abroad may have information stored across several systems, including:

• Nigerian passport & Foreign passport
• NIN & BVN
• Birth certificate & Marriage certificate
• Bank records & Academic certificates

Make sure your First name, Middle name, Surname, Date of birth, and Place of birth are accurate and consistent everywhere. Differences between documents can create problems with passport applications, banking, immigration procedures, property transactions, and official processes.

Nigerian Dual Citizenship After Marriage or a Name Change

Marriage is another issue that can affect Nigerians with Nigerian dual citizenship. For example, a Nigerian woman may have her maiden name on her Nigerian passport while using her married surname on her foreign passport.

If you legally change your name, keep supporting documents accessible:

• Marriage certificate / Divorce documentation
• Court documents & Affidavits (where required)
• Previous and current passports

Nigerian Dual Citizenship for Children Born Abroad

Children born outside Nigeria may be entitled to Nigerian citizenship by birth if they meet the requirements of the Nigerian Constitution. For many Nigerian families abroad, this is an important part of maintaining Nigerian dual citizenship across generations.

Parents should ensure they secure their child’s foreign birth certificate, evidence of the parents’ Nigerian citizenship, and the child’s Nigerian passport by contacting the nearest Nigerian diplomatic mission.

Nigerian Dual Citizenship and Property Ownership in Nigeria

Having Nigerian dual citizenship does not automatically prevent a Nigerian citizen from owning property in Nigeria. However, buying property from abroad requires careful due diligence.

Before purchasing land or property, read our step-by-step guides on how to safely buy a house in Nigeria from the diaspora and learn how to securely verify land titles in Nigeria from abroad. Be sure to review 5 red flags to watch out for when buying property in Lagos.

Nigerian Dual Citizenship and Inheritance

Nigerian dual citizenship does not automatically remove a Nigerian citizen’s ability to inherit assets in Nigeria. However, inheritance can involve complicated issues such as wills, probate, family law, customary law, and estate taxes. Obtain professional legal advice before transferring or selling inherited property.

Nigerian Dual Citizenship and Nigerian Taxes

Having Nigerian dual citizenship does not by itself determine whether you owe tax in Nigeria. Tax obligations depend on factors including tax residency, where income is generated, property income, and applicable tax treaties. Check our diaspora news and updates section regularly for changes in tax policies.

Can a Nigerian Dual Citizen Hold Political Office or Vote?

Nigerian dual citizenship does not automatically disqualify a Nigerian citizen by birth from participating in political life or holding certain offices. However, specific positions have strict constitutional requirements. Furthermore, voting rights are governed by voter registration requirements in Nigeria.
