My partner and I sent our application in July 2020, when I was living in Canada and he was in the UK. Since then I have been approved for a visa to the UK and have moved there to be with him while we wait for a decision. I would like to keep my address in Canada as my mailing address, should I get in touch with immigration to let them know I am in the UK, or wait for them to contact me? We do have confirmation they received our applications, and they have requested biometrics. Thanks.
