Indefinite leave to remain is how you settle in the UK. It’s also called ‘settlement’. It gives you the right to live, work and study here for as long as you like, and apply for benefits if you’re eligible. You can use it to apply for British citizenship.
There are different ways to apply for indefinite leave to remain based on your circumstances.
If you or your family member are an EU, EEA or Swiss citizen, you may be able to apply for settled status under the EU Settlement Scheme instead.
