I'm in Chiang Mai and have an ED visa. This month I need to do my 90 day reporting and extension at Promenada. Can those both be done in the same line? I've heard you can do part of it online but that it only works successfully part of the time....Is it true I should arrive at 4 or 5 am to stand in line? Can I also apply for a multi entry permit the same day? Or would it be more efficient to do that on a different day?
