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, you are normally required to register with the Overseas Visitor Records Office (OVRO). However, due to the coronavirus outbreak these offices are closed in most locations until further notice. You should contact your local police force to see whether you are still required to register in your area. The OVRO recommend that you keep a record of contact with them to show that you were unable to register during the period of temporary closure.
