Once you』ve applied online, proved your identity and provided your documents, you』ll usually get a decision within 8 weeks.
You』ll be contacted if your application will take longer, for example because:
your supporting documents need to be verified
of your personal circumstances, for example if you have a criminal conviction

You can ask to cancel your application. You』ll only get your fee refunded if UKVI has not started processing your application.
You』ll get an email containing the decision on your application. This will explain what you need to do next.

If your application is approved, you』ll be able to prove your right to live and work in the UK online.
If you』re given a BRP when your application is approved, you can also use that BRP to prove your right to live and work in the UK.
