What is the process to apply for a COVID extension in Thailand if I leave my job and lose my non-immigrant visa?

no. If you get an extension and the reason for that extension stops then so does the validity of the extension. You need to cancel your work permit and then go to immigration the same day. What Tod was referring to was your actual visa as in the sticker in your passport. You can’t cancel that but you must cancel an extension the same day as your last working day, or go a few days earlier to cancel and you’ll get a new stamp until your last working day.

if your employer allows get a letter saying you are finishing on xx/xx date maybe a couple of weeks in advance. Take that to the labour department to cancel your work permit then go to immigration with the documents they give you. You’ll get a new stamp until xx/xx date when you must either leave Thailand or sort out another alternative method to stay.

nope, doesn't work that way. IF you extend your Non-B for a year, and then you lose your job, you lose the extension. It's ONLY that first 90 days from the visa itself that you can stay on whether you work or not.
