For context, received my URN on May 20th and positive decision on June 21st. I'm switching visas within the UK and I've paid all my fees, including super priority for the biometrics appointment. I just have a few questions and I'm hoping someone who's gone through a similar process may have the answer:
> You must not travel outside of the UK, Ireland, the Channel Islands or the Isle of Man until you get a decision. Your application will be withdrawn if you do.
Does that mean only after the biometric appointment, assuming I can't travel anyways since they will have my passport? My situation might be slightly complex as I'm switching from a Tier 5 on one nationality to a Tier 1 on another nationality, but assuming once I go to my appointment I'll be turning in both passports.
Thanks for your help!
