Hello, my family and I have DTV visa and currently living in ChiangMai. But, by the time of extension of 180 day we are going to be in Koh Samui (smoky season in ChiangMai), Does somebody know or have experience with the immigration office in Koh Samui? Looks like it is a regular office but we can not afford to go Bangkok in case Koh Samui immigration office does not provide extension for DTV visa. I just want to double check to make some arrangements. Thanks you very much I really appreciate you answers.
