Hi all! We are a UK family of 6 in Chiang Mai. We are staying 12 KMs outside of Chiang Mai city centre.
Our 45 day initial visa exempt period ends on 15th Dec. We intend to extend by another 30 days. Are there forms we can fill in ahead of arrival to the immigration office? If so, how can I get hold of them? Our Air BNB landlord has filled out the TM 30 forms and showed us proof of this so that’s done. If we arrived at the immigration office early (e.g. 12th Dec), would the 30 day extension start from 13th or would they extend from 16th as per our 45 day visa exempt period end date stamp in our passports?
