When you're not subject to 'immigration control'
You're not subject to immigration control if any of the following applies:

you’re a UK national
you’re from the EEA or Switzerland
you’ve claimed asylum and you have been told by the Home Office that you can stay in the UK as a refugee
the Home Office has told you that you are allowed to stay in the UK indefinitely – known as 'indefinite leave to remain'
