Apply for Naturalisation as a British Citizen - Expert Naturalisation Solicitors

Naturalisation is the legal process through which a person who already holds Indefinite Leave to Remain (ILR) in the UK can apply to become a British citizen. Once naturalised, you will obtain the full rights of British citizenship, including the ability to apply for a British passport and live permanently in the UK without immigration restrictions.

Most applicants must wait 12 months after receiving ILR before applying for naturalisation as a British citizen.

However, if you are married to or in a civil partnership with a British citizen, you may apply for naturalisation immediately after obtaining ILR, provided you meet all other eligibility requirements.

To qualify for naturalisation after ILR, applicants generally must:

• Be 18 years or older
• Hold Indefinite Leave to Remain or Settled Status
• Meet the residency requirements
• Pass the Life in the UK Test
• Demonstrate English language ability
• Be of good character
• Intend to continue living in the UK

A specialist immigration solicitor at Premium Solicitor can assess your eligibility before submitting the application.

Applicants must meet strict residence requirements:

If not married to a British citizen:

• Must have lived in the UK for at least 5 years
• Must not have spent more than 450 days outside the UK during those 5 years
• Must not have spent more than 90 days outside the UK in the last 12 months

If married to a British citizen:

• Must have lived in the UK for 3 years
• Must not have spent more than 270 days outside the UK during those 3 years
• Must not have spent more than 90 days outside the UK in the last 12 months

Yes. Unless an exemption applies, most applicants must pass the Life in the UK Test, which demonstrates knowledge of British history, culture, and values.

If you passed the test previously when applying for ILR, you do not need to take it again.

Yes, unless you are exempt. Applicants must show knowledge of English by:

• Passing an approved English language test at the B1 level or above, or
• Holding a degree taught in English, or
• Being from a majority English-speaking country

The good character requirement is an important part of the naturalisation application. The Home Office will consider factors such as:

• Criminal convictions
• International crimes, terrorism and other non-conducive activity
• Immigration history
• Tax compliance
• Financial conduct or financial soundness
• Previous breaches of UK immigration law
• Deception and dishonesty
• Illegal entry in the UK

Any issues should be carefully addressed before submitting the application.

The good character requirement applies to applications for registration and naturalisation from those who are aged 10 or over at the time the application is made. The requirement for a person to be of good character in order to naturalise as a British citizen is set out in Schedule 1 to the British Nationality Act (BNA) 1981. Section 41A of the BNA 1981, as introduced by section 58 of the Immigration, Asylum and Nationality Act 2006, extended the good character requirement to specific routes to registration as a British citizen.

To be successful in their application for naturalisation as a British Citizen, an applicant must meet the good character requirement. While the British Nationality Act 1981 does not explicitly define good character, guidance provided by the Home Office UK Visas and Immigration (UKVI) outlines the types of conduct that are considered when assessing an individual's character.

Home Office caseworkers take into account various aspects of a person's character, including both negative factors such as criminal history, breaches of immigration laws, and instances of deception, as well as positive factors such as contributions to society. It's important to note that this list of factors is not exhaustive, and each case is assessed on its individual merits. Each application must be carefully considered by the Home Office UKVI on an individual basis on its own merits. The Home Office UKVI must be satisfied that an applicant is of good character on the balance of probabilities. 

Following recent changes to requirements for good character, applications for naturalisation as a British Citizen made after 10 February 2025 that include illegal entry will ‘normally’ be refused citizenship, regardless of when the illegal entry occurred.

The application is submitted to the UK Home Office using Form AN. Applicants must:

• Complete the online application
• Pay the Home Office application fee
• Upload supporting documents
• Attend a biometric appointment
• Wait for the Home Office decision

If successful, you will be invited to attend a citizenship ceremony.

Most naturalisation applications are decided within 3 to 6 months, although processing times may vary depending on the complexity of the case and Home Office workload.

Yes. A British citizenship application may be refused if the applicant does not meet the eligibility criteria, particularly the residence requirements, good character requirement, or immigration compliance.

Seeking advice from experienced UK immigration solicitors at Premium Solicitors can significantly reduce the risk of refusal.

The documents required for a naturalisation application may vary depending on the applicant's circumstances. Typical supporting documents include:

• Passport and travel documents
• Proof of Indefinite Leave to Remain
• Evidence of residence in the UK
• Life in the UK Test certificate
• English language certificate (if required)
• Two referees confirming identity
• Proof of lawful residence

Yes. Applicants must provide two referees who confirm your identity and suitability for British citizenship. One referee must be a professional person, and the other must hold a British passport.

If your application is approved, you must attend a British citizenship ceremony organised by your local council. During the ceremony, you will:

• Take an Oath or Affirmation of Allegiance
• Receive your Certificate of Naturalisation

You can then apply for a British passport.

No, you cannot submit your naturalisation application through Priority / Super Priority Service; the only option is to apply through standard service.

Criminal convictions may affect eligibility for naturalisation depending on their nature and severity. Serious convictions may impact eligibility, while minor offences may not necessarily be a barrier. It's essential to disclose all criminal convictions as part of the application process.

Family members, such as spouses and dependent children, can sometimes be included in a naturalisation application under certain circumstances. Each family member's eligibility will be assessed individually based on their circumstances.

The UK generally allows dual citizenship, meaning individuals can hold multiple citizenships simultaneously. However, it's essential to check the laws and regulations of your current country of citizenship to understand any implications of acquiring British citizenship.

A citizenship ceremony is a formal event organised by the local council or authority to welcome new citizens into the British community. It serves as a symbolic rite of passage where individuals who have successfully completed the naturalisation process take a solemn oath or affirmation pledging allegiance to the United Kingdom and its values.

Becoming a British citizen through naturalisation opens up a world of opportunities and benefits, including the right to live and work in the UK indefinitely, access to public services and benefits, the ability to vote and stand for public office, and the freedom to travel visa-free to many countries around the world.

Naturalisation as a British citizen is a significant milestone that offers countless opportunities for personal and professional growth. 

You must be aged 18 or over at the time of application to apply for naturalisation as a British Citizen.

Unless you apply for naturalisation based on crown service or as a member of HM forces, you cannot apply for naturalisation as a British Citizen until you have obtained Indefinite Leave to Remain (ILR).

The following can be used as evidence of residence in the UK:

• passports or travel documents which have been stamped to show arrival in the UK and entry and departure from other countries.
• if the applicant does not have passports to cover the qualifying period, other evidence such as employers’ letters or tax and National Insurance letters
• If there are gaps in a person’s evidence of residence and it is clear from the information available that they could not have travelled, the Home Office caseworker must accept this. Examples of this might include a refugee who has no means of travel or where immigration records confirm continuous residence.

A person who is married to a British Citizen is only required to show 3 years of residence to apply for naturalisation as a British Citizen. However, the applicant must also have Indefinite Leave to Remain (ILR) at the time of submitting the naturalisation application. In most categories, you cannot get Indefinite Leave to Remain (ILR) in the UK until you have lived in the UK for at least 5 years.

The future intention requirement for naturalisation as a British Citizen refers to the applicant's commitment to continue living in the United Kingdom indefinitely. It is a crucial aspect of the eligibility criteria that individuals must meet when applying for British citizenship through naturalisation.

The future intention requirement requires that the applicant intends to make the UK their permanent home and demonstrates a genuine desire to become an integrated member of British society. The Home Office typically assesses this Commitment as part of the naturalisation application process.

Yes, you can travel abroad after submitting your online application for naturalisation. You do not have to send your original BRP card and passport/travel document with the application. You can travel abroad while your application for naturalisation is pending with the Home Office UKVI.

However, you should not leave the UK in such a way that your intention to make the UK your main home is doubted by the Home Office UKVI. The Home Office UKVI can refuse your application for naturalisation if you have moved the centre of your life to another country after the online submission of your application.

When applying for naturalisation as a British citizen, it's essential to provide references or referees who can attest to your character, residency, and suitability for citizenship. 'Acceptable professional persons’ to act as a referee for an application for naturalisation as a British Citizen include:

Accountant | Airline pilot | Articled clerk of a limited company | Assurance agent of a recognised company | Bank or building society official | Barrister | British Computer Society (BCS) - professional grades which are Associate (AMBCS), Member (MBCS), Fellow (FBCS) | Broker | Chairman or Director of a limited company | Chemist | Chiropodist | Christian Science practitioner | Commissioner for Oaths | Councillor: local or county | Civil servant (permanent) | Dentist | Designated premises supervisors | Director or Manager of a VAT-registered charity | Director, manager or personnel officer of a VAT-registered company | Driving instructor (approved) | Engineer (with professional qualifications) | Fire service official | Funeral director | Insurance agent (full-time) of a recognised company | Journalist | Justice of the Peace | Legal secretary (members and fellows of the Institute of Legal Secretaries) | Local government officer | Manager or Personnel officer (of a limited company) | Member of Parliament (MP) | Member of Her Majesty’s Armed Forces | Merchant Navy officer | Minister of a recognised religion | Nurse (RN, SEN or holder of a BA in nursing) | Officer of the armed services (active or retired) | Optician | Paralegal (certified or qualified paralegals, and associate members of the Institute of Paralegals) | Person with honours (such as OBE, MBE and so on) | Personal licensee holders | Photographer (professional) | Police officer | Post Office official | President or secretary of a recognised organisation | Salvation Army officer | Social worker | Solicitor | Surveyor | Teacher, lecturer | Trade union officer | Travel agency (qualified) | Valuers and auctioneers (fellow and associate members of the incorporated society) | Warrant officers and chief petty officers

Naturalisation as a British citizen for members of HM Forces allows eligible foreign or Commonwealth nationals serving in the UK armed forces to apply for British citizenship even if they are exempt from immigration control. This route recognises the contribution of military personnel serving in the British Army, Royal Navy, or Royal Air Force and provides a pathway to citizenship under the British Nationality Act 1981.

A foreign or Commonwealth national is generally considered exempt from immigration control if they are serving members of HM Forces and therefore do not require leave to enter or remain in the UK under immigration law. This exemption applies to certain military personnel and their dependants while they are serving.

Yes. Members of HM Forces who are exempt from immigration control may be able to apply for naturalisation without first obtaining Indefinite Leave to Remain (ILR). Their exemption status can be treated similarly to settled status for the purpose of naturalisation, provided all other requirements are satisfied.

To qualify for naturalisation, applicants must usually:

• Be aged 18 or over
• Be serving or have served in HM Forces
• Be exempt from immigration control
• Meet the good character requirement
• Intend to continue living in the UK or serving the Crown
• Satisfy the English language requirement
• Pass the Life in the UK Test (unless exempt)

Each application is assessed individually under the British nationality legislation.

Yes. Applicants generally need to demonstrate a qualifying residence period, typically 5 years, before the application date. However, time spent serving overseas with HM Forces may still count toward residence requirements in certain circumstances.

Yes. Periods spent outside the UK due to military service may be treated as residence in the UK. This recognises that members of HM Forces may be posted abroad as part of their duties.

In most cases, applicants must pass the Life in the UK Test unless they fall within an exemption category, such as being aged 65 or over or having a medical condition that prevents them from taking the test.

Yes. Applicants normally need to demonstrate English language proficiency through an approved test or qualification unless they are from a majority English-speaking country or fall within an exemption category.

Applicants must show they meet the good character requirement, meaning they have complied with UK laws and financial obligations. The Home Office may consider factors such as:

• Criminal convictions
• Immigration history
• Financial conduct
• Military discipline records

Failure to meet this requirement can lead to refusal.

Yes. Spouses, civil partners, and children of HM Forces personnel may be eligible for British citizenship through different immigration or nationality routes, depending on their immigration status and residence in the UK.

Processing times can vary, but most naturalisation applications are decided within 3 to 6 months. Delays may occur if the Home Office requires further checks or additional documents.

The documents required for the application for naturalisation as a British citizen may vary depending on the applicant's circumstances. Typical supporting documents may include:

• Proof of military service in HM Forces
• Evidence of exemption from immigration control
• Residence history
• English language qualification
• Life in the UK Test certificate
• Referee declarations
• Valid passport or identity documents

Professional legal guidance can help ensure all required evidence is properly prepared.

If the application is successful, the applicant will be invited to attend a British citizenship ceremony, where they will:

• Take an Oath or Affirmation of Allegiance
• Receive a Certificate of Naturalisation

After the ceremony, they can apply for a British passport.

If an application is refused, it may be possible to:

• Request reconsideration of the decision
• Submit a fresh application
• Seek legal advice on available options

Each case depends on the reasons for refusal.

Naturalisation as a British citizen based on Crown service allows individuals who have been employed by the UK government or serving the Crown overseas to apply for British citizenship under special provisions of the British Nationality Act 1981.

Applicants who are engaged in Crown service outside the UK may qualify for British citizenship even if they do not meet the standard residence requirements normally required for naturalisation.

Specialist immigration solicitors at Premium Solicitors can assess your eligibility and guide you through the naturalisation application process.

Crown service generally refers to employment under the UK government or the Crown, including roles carried out overseas on behalf of the United Kingdom.

Examples may include:

• Employment with UK government departments
• Service with the British Armed Forces
• Diplomatic or consular service
• Employment with certain British government agencies overseas
• Other official roles carried out in the service of the Crown

Eligibility will depend on whether the employment qualifies as Crown service under UK nationality law.

You may be eligible to apply for naturalisation based on Crown service if:

• You are aged 18 or over
• You are of good character
• You are currently serving the Crown or have done so in the past
• Your service was outside the United Kingdom
• The Secretary of State is satisfied that granting citizenship is appropriate in your circumstances

Each case is assessed individually, and the Home Office has discretion when deciding these applications.

Holding Indefinite Leave to Remain (ILR) based on Crown Service is not a mandatory requirement, and the Home Office may exercise discretion in Crown service cases, particularly where the applicant has spent significant time serving the UK overseas.

Our British citizenship solicitors at Premium Solicitors can assess whether you meet the settlement requirement.

Standard naturalisation applications normally require applicants to:

• Have lived in the UK for at least 5 years
• Meet strict absence limits

However, for applicants serving the Crown overseas, the Home Office may waive or modify residence requirements due to the nature of the service.

This means time spent outside the UK while serving the Crown may still count towards eligibility.

In some circumstances, spouses, civil partners, or dependants of Crown servants who have been living overseas due to Crown service may also benefit from discretionary provisions when applying for British citizenship.

Each application is assessed individually, and applicants must still satisfy:

• Good character requirements
• English language requirements
• Life in the UK Test (if applicable)

The documents required for the application for naturalisation based on Crown Service may vary depending on the applicant's circumstances.  Typically, applicants applying for British citizenship based on Crown service may need to provide documents such as:

• Passport and identity documents
• Evidence of Crown service employment
• Letters from the relevant government department
• Proof of immigration status or ILR
• Residence and travel history
• Evidence of English language ability
• Life in the UK Test certificate

Proper documentation is essential to avoid delays or refusal.

Applicants must demonstrate that they are of good character. The Home Office may consider:

• Criminal convictions
• Immigration history
• Compliance with UK laws
• Financial conduct, such as bankruptcy or tax issues
• Any deception in previous immigration applications
• Illegal entry in the UK

Failure to meet the good character requirement can lead to a refusal of the naturalisation application.

British citizenship applications based on Crown service usually take around 3 to 6 months to be decided by the Home Office.

Processing times can vary depending on:

• Complexity of the case
• Verification of Crown service
• Additional checks by the Home Office

If your naturalisation application is approved, you will receive an invitation to attend a British citizenship ceremony.

At the ceremony, you will:

• Take an Oath or Affirmation of Allegiance
• Receive your Certificate of Naturalisation

After this, you can apply for a British passport.

Yes, the Home Office may refuse an application if:

• Eligibility requirements are not met
• The good character requirement is not satisfied
• Insufficient evidence of Crown service is provided
• Immigration rules have been breached

If your application is refused, you may be able to request reconsideration or submit a fresh application.
