My 3th and final extension of stay based on ED visa is coming to an end so I'm going to get a new one at Ho Chi Minh. I will be abroad when the extension finishes. Do I need to cancel it before I leave the Kingdom? I know when you have an extension based on work you need to cancel it, but not sure about this one? School says it isn't necessary and other students seem fine also, but I want to be sure. 😅 Jomtien immigration btw.
