We will be applying for a 30-day visa extension to our 45-day visa exemptions received in mid-November at Bangkok international airport. We are Canadians and will apply in person at the Central Festival Immigration office in Chiang Mai. Question #1: For the very first time, we did NOT fill in a TM.6 arrival/departure card when arriving from Taipei on EVA Air. Is this going to be a problem when we apply for a visa extension? We have only the small date stamps for 45 visa exemption in our passports. Question #2: I have also heard that some tourists here are being asked for TM30 forms from their hotels. Any comment on that? Thanks.
