I’ve never taken a TM30 to do an extension. Is this a new thing? The hotel does it when I’ve checked in so must be visible for then Immigration staff 🤷♂️
You could always book a throwaway ticket booked within the 60 days just incase you are asked. You could get the cheapest flight ticket or a bus ticket out of Thailand
Call an ambulance, go to the hospital, receive correct treatment and let your insurance deal with the payment. The hospital can also liaise with immigration regarding your visa 👌
and if you don’t then you still need an onward travel ticket if asked. They want to see that you are planning to leave the country within the visa/visa free timeframe
