When I cancel my work permit and non-B visa extension, do I have to cancel visa extension in immigration or can I cancel it in airport custom while I leave the country? If I don’t cancel visa extension in immigration, will it affect my next Non-B visa extension and next work permit application?
Asking because my flight time is too tight to cancel both before departure time.
TLDR : Answer Summary
When canceling your work permit and non-B visa extension, it's recommended to handle the cancellation at the immigration office rather than the airport customs, as failing to do so may complicate future visa applications. It's better to act proactively by getting a termination letter from your employer and canceling your visa and work permit in advance.
