Hi. Just need some advice. My employer doesn't want to cancel my work permit and visa (1yr extension) anytime soon. However, I want it to be properly cancelled so I won't have any problems when I find a new job here.

Should I just leave my work permit with them and let them send me a photo of the cancellation receipt once available?

I live in the province (12 hrs from bkk) and it would take an hour to visit the nearest immigration and labor office, so I can't go there without them. But I need to go to Bangkok this week already.
