Just got my work permit today, it has my old passport number on it as i recently got a new one, does that mean i need to carry both or is there a way to link the two?
TLDR : Answer Summary
After receiving your work permit with your old passport number, you do not need to update the work permit to reflect your new passport number. Instead, you can carry both passports. Additionally, any stamps such as Extension of Stay or re-entry permits from your old passport can be transferred to your new passport at the Immigration Office.
