Today i made a visa run to Laos, and after my return to Thailand i took my GF to go to the Udon Thani immigration office to submit a TM30. Actually the Udon Thani immigration office doesn't want one for the same place if you ever stayed there before, i asked about this when we filed a TM30 for the first time. But because we will move to Chiang Mai soon and from reading here i know that the immigration office there is a pain in the ass, i wanted to keep my record 100% legal.
