Thanks Stuart for clarifying. Office saying they will notify immigration the cancellation date of the Visa and work-permit effective 20 Jan 2023 (Which is last day on the Visa) but will do that 21 days in advance (reference image attached.) Does that sound legit they can do that in advance? Concerned they screw it up and I am stuck with overstay.
Yeh real world they will take a quick look at a paper or a photo on your phone that looks like a ticket. Download the app called Flightgen and u don’t even need to pay anything just take a screen shot example below took a few seconds to make.
