Last October I returned from UK and preregistered Jomtien. Went to do it again in Feb after Vietnam. Pretty much chased away, No need , no need. Went Vietnam again Songkran. Did not bother. 90 days reports and renewal and nothing said. Been to Chiang Mai 3 times then 90 day report. Not a thing said about not reregistering TM30 after a trip. They are too busy in Jomtien to worry about this is my guess.
