After you have lived legally in the UK for a certain length of time, you may be able to apply for permission to settle here. This is known as 'indefinite leave to remain'.
Your right to apply for settlement will depend on your current immigration category. You should read the UKVI section for your category to find out whether and when you can currently apply for settlement.
Following the UK withdrawal from the European Union (EU), if you are eligible for pre-settled, or settled status, this remains the most straightforward and cost-effective way for you to evidence your right to work in the UK.
EU citizens already living in the UK prior to 31 December 2020 can apply to the EU Settlement Scheme, the deadline for applications is 30 June 2021, but you should apply as soon as possible.
What is my immigration status while my application is being decided?
If you make an application before your authorised stay ends, your existing immigration status will continue until your application is decided, even if the decision is not made until after the end of your permitted stay. If your existing visa or other permission to stay here allows you to work, you can continue to do so until your case is decided.
