Question to the Home Office:

To ask the Secretary of State for the Home Department, if she will set out the the routes to British citizenship open to people who secure indefinite leave to remain having arrived in the UK by an irregular route after the 10 February 2025; and what estimate she has made of the cost of applying for naturalisation to this process.

An individual can apply for British citizenship if they believe they meet the requirements. Those wishing to naturalise will need to meet the statutory requirements set out in the British Nationality Act 1981, including to be of good character. Applications will be considered on a case-by-case basis, but a person who has entered the UK on irregular routes will not normally meet the good character requirement.

Details of fees for immigration and nationality applications, including the estimated unit costs, can be reviewed via the following link: https://www.gov.uk/government/publications/visa-fees-transparency-data.
