INTRODUCING UK NATURALISATION VISA
Unless you are British by descent, to become a UK citizen you have to apply to the Home Office through the process of British Naturalisation. With British citizenship, you can apply for a British passport, vote, and live and work in the UK free from immigration controls.
Requirement of Naturalisation Visa
If you are married to a British citizen, you can apply for British Citizenship by Naturalisation as soon as you have been granted Indefinite Leave to Remain. You will need to satisfy all of the other requirements for British Citizenship by Naturalisation outlined above. If you are not married to a British citizen, you will need to have been free of immigration time restrictions for at least 12 months immediately preceding the date of your application. This means that you will be eligible to apply for British Citizenship by Naturalisation 12 months after being granted ILR.
In order to qualify for UK Citizenship, you will need to have spent not more than 90 days outside the UK during the 12 month period immediately before the date of your application for British Citizenship by Naturalisation. If you are not married to a British citizen, you will also need to have not been away from the UK for more than 450 days days during the preceding 5 years. If you are married to a British citizen, you will need to have spent not more than 270 days outside the UK in the previous 3 years.
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 the ‘good character’ requirement will be 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-related matters.
