Hi, is it possible to cancel a non-B extension ~1.5 months before last working day? I’m thinking about quitting my job from abroad but cancel the extension while I’m still in Thailand. Thank you!
TLDR : Answer Summary
To cancel a non-B visa extension about 1.5 months before your last working day, you'll need to obtain paperwork from your employer confirming your end date. Once you have this, you can cancel your work permit. After that, you should go to immigration to have your current stamp canceled and receive a new stamp valid until your indicated end date.
