Can Nigerian nationals hold dual British and Nigerian citizenship?

Yes. Nigeria permits dual nationality, and the UK allows British citizens to hold other nationalities. You do not need to renounce your Nigerian citizenship when you become British. You can hold both passports and travel on whichever is most convenient.

What documents do Nigerian nationals need for a UK citizenship application?

You need your current and previous Nigerian passports, your UK BRP, proof of English language ability, evidence of your Life in the UK test pass, proof of continuous residence, and two referees. If any Nigerian documents are not in English, you need certified translations.

How long does it take for a Nigerian national to become a British citizen?

The typical path is 5 years on a qualifying visa, then indefinite leave to remain, then 12 months with ILR before applying for citizenship. The citizenship application itself takes around 6 months to process in 2026. The total journey from first arriving in the UK is usually 6 to 7 years minimum.

Do I need to inform the Nigerian government if I become British?

Nigeria does not require you to formally notify the government when you acquire another citizenship. However, if you intend to continue using your Nigerian passport, ensure it remains valid. Some Nigerian nationals choose to inform the Nigerian High Commission in London for their own records.

British Citizenship for Nigerian Nationals: Complete Guide

Nigerian nationals can become British citizens through naturalisation after meeting the standard residency and eligibility requirements. Nigeria permits dual nationality, so you do not need to give up your Nigerian passport. This guide covers the full process, Nigeria-specific document requirements, and practical considerations.

Dual Nationality: Nigeria and the UK

One of the most important facts for Nigerian nationals is that both Nigeria and the UK permit dual nationality. This means you can become a British citizen without giving up your Nigerian citizenship. You can hold both passports simultaneously and use whichever is most convenient for travel.

This is a significant advantage. Some countries require their nationals to renounce their original citizenship before acquiring a new one. Nigeria does not. The Nigerian Constitution, as amended, recognises that Nigerian citizens may hold other nationalities.

The Path to British Citizenship

The standard route to British citizenship for Nigerian nationals follows the same steps as for all non-EEA nationals:

Qualifying visa: Arrive in the UK on a visa that leads to settlement, such as a Skilled Worker visa, spouse visa, or other qualifying route.
Indefinite leave to remain (ILR): After 5 years of continuous residence on a qualifying visa, apply for ILR. Some routes, such as the spouse visa, allow ILR after a shorter period.
Citizenship: After holding ILR for at least 12 months, apply for British citizenship through naturalisation.

The minimum total time from arrival to citizenship is typically 6 years (5 years to ILR plus 1 year with ILR), though some routes may be shorter.

Documents You Will Need

Nigerian nationals should prepare the following documents for their citizenship application:

Current Nigerian passport and any previous passports used during your time in the UK
Biometric Residence Permit (BRP) showing your current immigration status
Birth certificate: Your Nigerian birth certificate. If it is not in English, you will need a certified translation
Life in the UK test certificate
English language evidence: A qualifying test pass or degree taught in English. See our guide on English for citizenship
Proof of residence: Bank statements, utility bills, payslips, or HMRC tax records covering the qualifying period
Two referees who meet the Home Office requirements. See our referees guide

English Language Requirement

Although English is the official language of Nigeria and widely spoken, the Home Office does not automatically exempt Nigerian nationals from the English language requirement. You must demonstrate your English ability through one of the following:

A degree taught or researched in English (including degrees from Nigerian universities where the medium of instruction was English, provided the degree is recognised by UK ENIC)
A SELT (Secure English Language Test) at B1 level or above
Being a national of a majority English-speaking country is not sufficient on its own for citizenship applications, unlike for some visa categories

Many Nigerian nationals use their Nigerian university degree to meet this requirement. Check that your institution and qualification are recognised by UK ENIC.

Absence Rules

Many Nigerian nationals travel back to Nigeria regularly to visit family. Be careful with your absences, as the citizenship residency requirements are strict:

No more than 450 days outside the UK in the 5 years before your application
No more than 90 days outside the UK in the 12 months before your application

Track your travel carefully. Each trip to Nigeria counts, including short visits. Use our residence calculator guide to check your eligibility before applying.

If you have exceeded the limits, you may still be able to apply using the Home Office's discretion. See our guide on discretionary absences.

The Good Character Requirement

The Home Office assesses whether you are of "good character" as part of the citizenship application. This includes checking:

Criminal records in the UK and Nigeria
Immigration history (any breaches of immigration conditions)
Financial soundness (including tax compliance)
Deception in previous applications

Minor traffic offences or old, spent convictions are usually not a problem. However, any serious criminal convictions, ongoing criminal investigations, or evidence of immigration fraud can result in refusal. Be completely honest in your application.

Applying for Citizenship

The application is made online through the GOV.UK naturalisation page. The current fee is £1,344, which includes the £130 ceremony fee. This fee is non-refundable even if your application is refused.

Processing times in 2026 are typically around 6 months, though this varies. For faster processing, see our guide on the priority service.

After Becoming a British Citizen

Once you receive your citizenship certificate at your ceremony, you can:

Apply for a British passport
Register to vote in all UK elections
Travel more freely with your British passport
Access the full range of public services without conditions

You should also consider the tax implications of dual nationality, particularly if you have income, property, or assets in Nigeria.

Nigerian Community in the UK

The Nigerian diaspora in the UK is one of the largest and most established. Major Nigerian communities exist in London (particularly Peckham, Woolwich, and Barking), Manchester, Birmingham, and other cities. These communities offer valuable support networks for new citizens.
