My teacher's WP expires on 24 April and I have a flight booked back home on the 6 May. I don't want to change the date of my departure.

I am thinking of doing a visa run to Cambodia on 24 April to get a 14 day visa on arrival. I don't have a reentry permit for the existing visa.

This will cancel the existing visa and give me a new visa with the 14 days I need until 6 May.

Or can I only get a visa on arrival at an airport?

You can obtain a 15 day visa exempt entry at a land border but it seems you have an extension of stay so you must cancel that before you make your border trip (requirement is last day of work with a letter from employer) or you could be refused permission to depart until you do. Once you cancel the extension you can cross border and return for that 15 day entry.

I thought just by leaving the country I cancel the extension to stay.

While true, the correct procedure is to cancel the work pemit (if not expired) and the permission to stay. Only then can immigration know when your job ended and be sure you were not on overstay.

Thank you for the replies. Plan is to go to Labour the following day (25th) to cancel the WP.
