My ED extension expires tomorrow and I was going to cancel the extension today. But given the massive crowd at Chaengwattana today, I am having second thoughts and thinking of cancelling it only when I return to Bangkok again.
I plan to return to Bangkok only after I obtained my Non-B instead.
Would it be a big issue to cancel the extension only after I return back to Bangkok? What is the advice of the sages here? Should I try to cancel it tomorrow before before catching my flight instead? How complicated and how much time do I need for the cancellation?
