Applying for citizenship in UK
To acquire British citizenship, you will have had to spend a certain period of time in the UK. The specific time requirement is based on your current immigration status, prove their English language and pass the Life in the UK test.
Ways to obtain British Citizenship are as follows:
- You were born in the UK
- By Descent – you may be recognized as a British national if you were born in the UK after 1st January 1983 or if you were born abroad, outside the UK from at least one British parent who is a British citizen or settled person.
- By Marriage – as the spouse or civil partner of a UK citizen, you must first have spent at least 3 years in the UK as a settled person (by holding Indefinite Leave to Remain or EU Settled Status).
- 5-year route – After 5 years of residence in the UK, applicants are eligible for Indefinite Leave to Remain. After a year, as a settled person, you are permitted to submit a British citizenship application to process for British nationality. The same applies to EU and EEA citizens on the EU Settled Scheme.
- Citizenship for “stateless” individuals – If you are considered “stateless” (not a national of any state) you may be eligible to become a British citizen. The British citizen application process will depend on the country where you were born.
- Nationality for people who renounced it. If you renounce your British Citizenship, you may be allowed to resume your status as a British citizen.
Requirements to obtain UK citizenship
As per legislation under the British Nationality Act, anyone who wants to pursue a British citizenship application must:
- Be 18 years or over
- Have spent at least 5 years of continuous residence in the UK, not extending 450 days outside the UK
- Have Indefinite Leave to Remain, ILR status, in the UK for at least 12 months.
- Reach the English language requirements (if applicable)
- Pass the Life in the UK test, showing you understand British nationality, British culture, customs, and traditions.
- Meet the ‘Good Character’ requirement
- Intention to reside in the UK
Tests for citizenship in UK
Life in the UK test
You need to pass the Life in the UK Test before you apply for British citizenship. The test asks questions about UK laws and the legal system, working, and other details of life in the UK. The minimum mark required to pass is 75%.
You can do the test any time before you apply for citizenship and can do it as many times as it takes to pass, but you’ll have to pay a fee every time. The cost for the Life in the UK test is £50.
You don’t need to take the Life in the UK Test if you have already passed it in the past, are under 18 or over 65 years old, or if you have a medical or physical condition that permits you from taking the test, confirmed by a doctor’s note.
Knowledge of English language
Applicants for UK citizenship must generally prove their English language ability.
You can do this by either passing an approved English language test at English level B1, B2, C1 or C2, or by showing proof of an academic qualification that was mostly taught or researched in English.
If you previously used a test result to verify your application for indefinite leave to remain and the qualification has run out, you still may be able to use it as long as you can prove that it was accepted when you applied for settlement in the UK.
You will not need to prove your English language ability if you’re aged 65 or over, unable to due to a long-term physical or mental condition, or if you’re from one of the exempt majority English-speaking countries.
"Good Character" requirement for British citizenship
To be eligible for British citizenship, you must prove that you are of “good character”.
There is no formal criteria for this term and applications are always taken on a case-by-case basis at the discretion of the Home Office caseworker.
However, according to Home Office guidance, caseworkers generally look at the following types of information when assessing whether a person is of good character or not. These include (but are not limited to):
- If the applicant has a criminal record or has reasonable grounds to suspect them of criminal activity
- If they have been associated with international war crimes, crimes against humanity, genocide or terrorism
- If they are financially stable, such as not having accrued significant debt or having failed to pay taxes
- If they have been found to be guilty of deception or dishonesty, such as lying to the UK government in official immigration or benefits forms
- If they have previously breached immigration rules
- If they have previously been deprived of citizenship before
Caseworkers can still refuse citizenship applications if there are general doubts about an applicant’s character. Assessments may also be made via in-person interviews.

British citizenship absence rules
Generally, you must have spent at least 5 years living continuously in the UK prior to your application for citizenship.
You also should not have spent more than 450 days outside the UK during the 5 years before your application, and not spent more than 90 days outside the UK in the last 12 months.
You also must not have broken any UK immigration rules during your whole stay in the UK.
Note that your application for citizenship may be refused if you were not in the UK for exactly 5 years when the Home Office receive it.
Referee for British citizenship
You must have your citizenship application endorsed by two referees.
One referee can be of any nationality but must be working as a professional in a verified job occupation. The other referee must hold a UK citizen passport and either a professional person or over the age of 25.
Acceptable professional job roles include medical professionals, social workers, civil servants, bank or building society officials, accountants or teachers.
Each referee must have known you for at least 3 years and must not be related to you, the other referee, a solicitor or agent representing you, or a Home Office employee.
What documents do I need to apply for British citizenship?
Completing and submitting the correct documents is imperative as part of the British citizenship application form. Having the correct documents will also speed up the processing time of the home office.
Evidence required includes:
- Evidence of identity and permanent residence statuses – such as your passport, birth certificate, or any other valid travel document.
- Biometric Residence Permit (BRP), residence card, or other proof that you hold Indefinite Leave to Remain or EU Settled Status.
- Previous immigration status and right to remain in the UK, including any visa that you held before you settled in the UK.
- Proof of English language requirement
- Passing the Life in the UK test
- Evidence of lawful residential presence in the UK during the qualifying period.
- Any details of time outside the UK
- You meet the good character requirement and you have never been in breach of any UK immigration laws
- References from two people: your application requires two referees of your choice. Their role is to confirm that the information you have provided on your form is correct. Without your referees’ signatures, your request cannot be valid, and it will be rejected. Both your referees must both have known you for at least three years, and they cannot be related to you or to each other. In addition, they must not have had any criminal convictions within the last ten years.
How to apply for British citizenship?
Applications for British citizenship can be made online via the official gov.uk website or on paper if you live outside of the UK.
The complete steps in order to apply are as follows:
- Confirm your eligibility against the official criteria and ensure that you meet all the points necessary, including the residency, language and good character requirements.
- Fill in the application form fully and accurately.
- If applying online, upload your supporting documents and pay the application fee. If applying on paper, ensure you have securely bundled your form and documents together along with the payment slip.
- Attend your biometrics appointment to give your fingerprints and photo.
- Await your decision from the Home Office.
- If your application is approved, attend a citizenship ceremony and receive your certificate of naturalisation.
Note that you will be legally obligated to return any physical biometric residence permits you still own to the Home Office within five working days of receiving your certificate.
British citizenship application form
The form that UK citizenship applicants will have to fill in is known as Form AN.
You will have to ensure that you are filling in the correct form when applying, as not doing so will cause your application to be null and void.
Form AN is available either online via the Home Office website where it can be filled in using the interactive form tool, or as a PDF where it can be printed out and filled in physically.
British citizenship ceremony
As per the British Nationality Act, applicants over 18 that have a successful British citizenship application are required to take part in a Citizenship ceremony, to fully welcome them to the British community.
Ceremonies have to be booked within 3 months of the date you received an invitation from the Home Office. You are permitted to bring one guest to your service. However, these ceremonies are not open to the public.
You must bring with you your Home Office letter of invitation and written confirmation from the Register Office.
During the citizenship ceremony, you will be asked to take an Oath of Allegiance and pledge of loyalty to the United Kingdom government. After this rite, you will receive your British nationality certificate and an information pack to learn more about your new rights and responsibilities as a UK citizen.
Once you have satisfied all the requirements for British Citizenship and gotten your certificate of Naturalization or British citizenship registration status at your citizenship ceremony, you can apply for a British passport.
It usually takes around six weeks, and the UKVI may invite you to a separate interview for this.
British citizenship application fee
It costs £1,605 to apply for British citizenship by naturalisation. If applying for your child, the fee is slightly reduced at £1,214.
If applying to naturalise as a British overseas territory citizen, the fee is £1,070.
You may also have to pay an additional £130 to attend a citizenship ceremony, though this is normally included within the application fee.
UK citizenship processing time after biometrics
Applications for UK citizenship typically take up to around 6 months to be processed.
Your application may take longer if it is complex or if the Home Office needs to reach out to you for further information. You will normally be informed before the 6 month period is up if your application will take longer.
Note that you must also attend a citizenship ceremony within 3 months of your application being approved and you being sent an application from the Home Office.
What if my citizenship application is refused?
If your application for citizenship is refused, you will unfortunately have no right of appeal.
However, you may have the option to request a reconsideration. Reconsiderations should only be requested if you genuinely believe that there has been an error in the processing of your application or your case has been judged unfairly due to certain circumstances.
Circumstances where this may apply include if you believe not all supporting evidence was taken into account when processing your application, if the application was not judged on the correct criteria, or if you were accused of not responding to enquiries when you actually did provide a response.
If you do not wish to request a consideration, you will have the option to submit a new application for citizenship. However, you must ensure that you have fully addressed the original reasons for your application being refused. You will also have to pay the application fee again.
British passport after citizenship in UK
After you have attended your citizenship ceremony and received your certificate of naturalisation, you can submit an application for a British passport immediately afterwards.
Applications for passports can be made online or on paper. You will need the information on your certificate of naturalisation in order to apply.
It costs £94.50 to apply for an adult passport online, or £107 to apply for an adult passport by post.
Registering a child as a British citizen
Applicants must be 18 years old before they are eligible to apply for naturalization, but you can register your children for citizenship at any age. If your family has IRL status, you can include them in your application.
Children 13 or older, qualify for Naturalization if they have been living in the UK for at least two years prior to their application for naturalisation.
Children born in the UK before you obtained ILR or EU Settled Status, for example may acquire an entitlement to be registered for citizenship as soon as you obtain your settlement status.
Any child born in the UK from non-British parents who are already settled in the former mother’ country automatically acquires citizenship at birth.

Frequently Asked Questions
For obtaining British citizenship for those over 18 it costs £1,605 or for those under 18 £1,214
Dual citizenship means that you have British citizenship and another country of your choice. The UK allows for its citizens to hold more than one nationality. You don’t need to register for dual citizenship according to the UK rules, but the other country may have its own requirements.
If you have previous offences and/or convictions, they will likely affect your eligibility for citizenship, although this does depend on the type of conviction or offence and their seriousness.
You should ask people who you have known for at least three years and they must be over 25 years old. While one of them must be a UK citizen, the other can be of any nationality provided that he or she is a professional (i.e. police officer, accountant, doctor, or lecturer).
