What is the expiration date on your ARC?
Expiration date on ARC is just a reference. Find out when your company sent the cancellation of your ARC’s work permit to CLA. The NIA should have that information.
Not that I want to scare you, but they could have sent that a week ago meaning you’re out of time… Go to teh nearest NIA and hence you won’t have room for guesswork.
The only thing you can use to extend the ARC would be another work contract. If you will stay studying or something , you must leave the country and return. If you just want a few more days to get your stuff in order before leaving, then your plane ticket should suffice.
