I do not understand how ridiculous some of the responses are to questions in this thread. Common sense says if you move, you update your address PERIOD..That would be the same as me saying I moved to a different condo in a 46 floor building. It may be the same building but my physical location has changed within that building. Bottom line is use common sense and do the TM-30. Some immigration offices require even when you leave simply for a short week or two from Thailand. When I leave to travel to Vietnam or just to go back to the USA I still do a new TM-30 regardless when I return. It’s not like it is expensive or anything.
