Z visa to an X1 type

Michael, as you are holding a Z type at present, I believe you have a temporary residence permit, right? If the remaining validity of the residence permit is relatively long, it is more likely to change the Z type into an X1. Anyway, it’s possible to do so at the relevant exit and entry administration agency. If being denied by the officer, I think you can try to do it in Hong Kong, but not guaranteed to get it.
