Just returned to Don Mueang from Siem Reap. I am the holder of a Non O-A visa which is due to expire tomorrow 21st March. Following the information of others I had already downloaded the AOT app, registered and filled out the required information which presented me with a QR code. Went straight through the thermal scanning and the next stage after showing the QR code. Was stamped in for a year and wasn’t asked for insurance although I did have it with me just in case.
