When you do 90day report, only the current address matters. So you need the tm30 for that. Im not sure if previous missing reports since your stamp might be an issue, i have never seen a post of it being, so i dont think its a problem... not your responsibility anyway
Anonymous participant 474 not true, its for visaruns. DTV holder has a visa, so its only a border run. I have done it cambodia in feb and laos in 2weeks ago.
sorry i meant receipt of notification, which has to be updated after every entry before tm47, the small paper they put in your passport, not only tm30 done online
