Hello! I'm in the UK and I'm planning on going to Thailand in the next few days (with a visa exemption, for 30 days). Can I get a 60 day Covid visa extension when I'm in Thailand to stay a total of 90 days? Or is there any other way I can stay for 90 days in Thailand having entered only with a 30 day stamp? I know I can apply for a 60 day tourist visa but I'm afraid that might not come back in time for my flight. Thank you :)
