How can I get British citizenship through marriage?


we are often asked "can I apply for British citizenship after 3 years of marriage to a UK citizen?" If you are lawfully married to a British national, you may be eligible to apply for British citizenship by marriage after holding Indefinite Leave to Remain (ILR) or settled status, with no requirement to wait 12 months after ILR approval.

 

Key requirements include:


•    Physically present in the UK exactly three years before the submission date
•    No more than 270 days of absence from the UK in the last 3 years
•    No more than 90 days absence in the last 12 months
•    Must pass the Life in the UK Test and the B1 English language requirement
•    Free of immigration restrictions at time of application
•    Must satisfy the ‘Good Character’ requirement

 

How long do I Need ILR before applying for British Citizenship?


If you are not married to a British citizen, you can apply after residing lawfully in the UK for five years and holding ILR for at least 12 months.

 

You must meet the following:


•    Present in the UK exactly five years prior to applying
•    Fewer than 450 days of absence during those five years
•    Fewer than 90 days of absence in the last 12 months
•    No breach of immigration rules during the qualifying period
•    Must pass the Life in the UK Test and B1 English exam
•    Satisfy the ‘Good Character’ criteria
•    Must intend to make the UK your permanent residence

Whether applying via the spouse route or independently, the following must be evidenced:

​

  • Legal immigration history with no infractions

  • Proof of residence and absence thresholds compliance

  • Passing of both the SELT B1 English test and the Life in the UK Test

  • Disclosure of any past convictions or conduct affecting your good character status

  • Intent to remain in the UK permanently

  • Fulfilment of biometric enrolment within 45 days of submission

British Citizenship for EEA and EU Nationals
​

EEA nationals and family members must hold Settled Status (or prior permanent residence) for 12 months before application. No separate document is required, but sufficient evidence must be submitted. Nationals granted ILR through other UKVI routes may also be eligible, provided they meet the full 12-month threshold post-ILR and satisfy character, testing, and residence criteria.

British Citizenship by Marriage to UK National & Applying Straight After ILR?
​

If you are married to a UK National, you can apply as soon as you have been granted ILR.  You will need to satisfy all of the other criteria as outlined above.  If you are not married to a UK national, you will need to have been free of immigration control restrictions for at least 12 months immediately preceding your submission.  This means that you will be eligible 12 months after being granted Indefinite Leave to Remain to apply.

 

​Absence & Travel Considerations
​

What are the residence requirements for UK Citizenship and how many days can I be outside the UK when applying for citizenship?

​

You must not exceed:

  • 90 days outside the UK in the 12 months before your application

  • 270 days over 3 years (spouse route)

  • 450 days over 5 years (Indefinite Leave to Remain route)

 

Travel during the application is permitted, but you must:

​

  • Submit a certified passport copy

  • Retain your original passport 

  • Ensure valid re-entry rights (Indefinite Leave to Remain/e-visa)

  • Attend biometric appointment within 45 days of submission

 
What is the good character requirement for British Citizenship?
​

Naturalisation applications include good character assessment for UK citizenship. The British Nationality Act 1981 requires any person who wishes to naturalise as a British Citizen to be of ‘good character’. ‘Good character’ is not defined in the Act, but Home Office nationality policy guidance explains how ‘good character’ requirement is assessed.  This contains a non-exhaustive list of conduct that will mean that an applicant is not of ‘good character’ including criminality, terrorism, financial soundness, notoriety, deception and dishonesty and immigration rule breaches.

​

It is important the requirements are given careful consideration as any application for British Citizenship where there is any possible or apparent doubt (harmless or not) can lead to refusal.  Advice from an immigration adviser is recommended to ensure any potential issues are identified and properly addressed as part of your submission needs.

 

SELT English Language Test for British Citizenship
 

If English is not your native tongue you will need to meet language test criteria there are 3 different levels you need to pass to become eligible and you will need to pass the B1 language test.

 

  1. SELT level A1 applies for Entry clearance (UK Spouse visa)

  2. SELT level A2 applies for FLR (UK Spouse visa)

  3. SELT level B1 applies for Indefinite Leave to Remain

Life in the UK Test Requirement
​

Before you can submit your application you will have to completed the "Life in the UK Test" and achieve a pass, Life in the UK test certificates doesn't have an expiration date. For more information about "Test for UK Citizenship" checkout our post.​​​​

​

Referees for British citizenship applications?

 

​Referees: Who Can Vouch for You?

​

Two referees are required:

​

  • One must be a British citizen aged over 25 or a person of professional standing

  • The second can be of any nationality but must hold professional status and must not be involved in your application

​​

Examples include doctors, lawyers, ministers, teachers, or civil servants.

 

Cost?

​

The Home Office application fee for an application to become a British National is £1,330.  You will need to spend a further £80 to attend your British citizenship ceremony.  

 

How long does it take?
​

Applications for Naturalisation as a British Citizen normally take up to 6 months to process by the Home Office.  But the application process can be streamlined submitting through an immigration adviser who understands the nuances that can delay an application decision.    

 

Leaving the UK while your application is under consideration?
​

You can apply for British Citizenship and travel outside the UK while your application is being considered.  When you apply for British Citizenship, you can submit a full certified copy of your passport and keep your original passport with you.  You can then use your original valid passport to travel overseas, however you should only do so if you have evidence of your Indefinite Leave to Remain, or other valid immigration status to re-enter the UK again. But bare in mind you will need to enrol your biometric information within 45 days of submitting your British citizenship application. Failure to provide biometric information when required will invalidate your application.

 

Attending your ceremony?
​

If your application is successful, you will have to attend a citizenship ceremony where you will give your oath of allegiance to the king. At the end of the ceremony you will receive your certificate of naturalisation as a British citizen.  You can then use it to apply for  your 1st British passport.

​

BOTC’s, BNO’s, BOC’s & BPC's?
​

If you are a British Overseas Territories Citizen, a British National (Overseas), a British Overseas citizen, a British subject, or a British protected person you are not a British citizen yet; you will likely have to apply for British citizenship through registration instead.
