I just received my Thai pass (it took less than 24 hours from submitting). I have my quarantine hotel booked, bought required insurance, and have my flights booked to fly to Thailand on November 17th. I applied for a 60 day visa but have not heard back so I don’t think I will receive my visa in time for my flight. I have 2 questions.
1. I have a US passport. Is it possible to enter Thailand on a 30 day visa exemption and then extend for another 30 days while in Thailand ?
2. If this is possible, I will have to temporarily change my return flight to be less than 30 days from arrival (in order to get through immigration). This return flight will no longer match what I filled out for my Thai pass. Will that be a problem?
