Am I still required to register with the police within 7 days of arriving in the UK or receiving my new BRP?
If you have been identified as an individual who has to register with the police, and you live in the London area, you are normally required to register with the Overseas Visitor Records Office (OVRO). However, due to the coronavirus outbreak these offices are closed until further notice. The OVRO recommend that you keep a record of contact wth them to show that you were unable to register during the period of temporary closure. For all other areas in the UK, you will still be required to register with your local police force.
