It looks like some countries are exempt from applying for visas in Thailand which is the case from here in Australia. When I go there and it's at least once a year. I bring a copy of the digital card, accommodation and flights. I also bring a copy of my meds from my doc just in case. Looks like the countries not exempt are required to provide more info
