UK Permanent resident card, also known as Indefinite Leave to Remain, UK permanent residence is an immigration status granted to a person without the right of abode. An individual with permanent resident status can live and work in the UK indefinitely. You will no longer have any immigration restrictions on working or business in the UK and no time limits on your stay. If you hold this immigration status, you can also become eligible to certain entitlements, such as welfare benefits and tax credits.
There is no time limit on Indefinite Leave to Remain in the UK, however it is important to note that you should not spend periods of more than two years outside the UK as this may lead to the loss of ILR. You may be eligible to apply for British Citizenship 1 year after being granted Indefinite Leave to Remain.
