So I have just tried to cancel my extension of stay with a letter from my employer stating my employment was finished at my local immigration. They won't do it without cancelling work permit first. My employer doesn't have the paperwork ready to cancel the work permit yet. It ends Monday along with the extension of stay. Was leaving the country on Sunday. Am I likely to be stopped at a land border?
TLDR : Answer Summary
The user is facing difficulties in canceling their extension of stay in Thailand because their employer has yet to process the cancellation of their work permit, which needs to happen first. They are concerned about potential issues when leaving Thailand by land, especially since they plan to exit shortly after their extension ends.
