British citizenship
Becoming a British citizen comes with many benefits. British citizenship will grant you permanent residence in the UK but you will also be entitled to the same rights as all other British citizens. This means that as well as permanent residence there are other benefits that you do not get with Indefinite Leave to Remain. This includes being able to vote in all UK elections and being able to apply for a British passport which can be used to travel freely in and out of the country.
With British citizenship you will be free of immigration restrictions, this means you can leave the UK for as long as you like and still maintain your right to permanent residence. Having citizenship means that you can also claim public funds.

Becoming a British citizen is usually a complex process no matter which route you use, but there are several routes available. The right route for you will depend on your circumstances, you can become a British citizen using any of the following routes:
- Naturalisation – for overseas nationals who have lived in the UK for 5 years and hold Indefinite Leave to Remain or settled status

When applying for naturalisation you will also need to prove your identity by having your biometric details (photograph and fingerprint scans) collected at your nearest UKVCAS centre.
If your application to become a British citizen is approved, you must then attend a British citizenship ceremony.

- You were born on or after 1 July 2006 and at least one of your parents was a British citizen or had settled status at the time of your birth
If you do not qualify as an automatic citizen by meeting any of the above criteria, you could still be eligible to register as a British citizen if any of the following apply:
- You were born after 31 December 1982 and before 1 July 2006 and both of your parents were not British citizens or settled in the UK, or your father was a British citizen or had settled status in the UK and was not married to your mother
- You were born on or after 1 July 2006 and neither of your parents had British citizenship or settled status at the time of your birth
