Basically Bonitanita as British citizens (Visa exempt) Once we get to stage 2 of the app we might not hear anything at all (not sure if London VO issues AOR) they will contact us if any additional documents required i.e medicals expired, supporting evidence or if police check needs updating. You will keep your pp through out the process.
I hope I do hear something as I wish to add further documents myself but my file is somewhere between Miss and Lon VO so at the moment I have to sit tight and wait until my wife tells me her sponsorship has been approved and I know for sure London has the file, right now I suspect she has been approved but cant send additional information because I am not sure if my file is in London or Canada lol
If your package does not require any additional information, yes your copy of COPR might be the first you hear from Lon VO.
