When you arrived HK (from USA), are you supposed to already have a QR code to show your covid vaccine status, or do they give you a covid test on the spot, and then give you a QR code, which you can then use in the leave home safe app?
If it's the former, how do you go from having USA covid vaccine records (several vaccination cards), to having a HK vaccine QR code? I read somewhere you take a health declaration form, answer some questions and they give you the QR code, but you cannot do it until 24 hours before departure because you need to take a covid test before filling in the declaration form. Is this correct?
I like to prepare my stuff way before 24 hours before departure so this makes me nervous.
