Visa application with invalid(?) residency permit
Australian living in Germany, applying for UK Youth Mobility Visa. I've recently had a new Aus passport however my current German residency permit is tied to my old passport (the old passport number is printed on the card). Am I still able to present the correct residency permit at my biometrics appointment or do I need to have absolutely everything up to date? Alternatively can I present the permit and BOTH passports?
Apologies if obvious questions are obvious, but I don't know how much leeway the UK authorities give on these matters and some helpful advice would be appreciated. Thanks.
