If you are over 50 you can apply for a Visa based on the fact you are over 50 but need 30 days minimum on your current Visa. As you are here in the Covid-19 amnesty you cannot apply and will have to leave and apply from outside if Thailand or come back at a later date on a Visa (not Visa exemption stamp) and change then. Either way you cant do it in your position now.
If you are not in Thailand at the moment you will need to apply for a new Visa and I dint think any embassies are issuing at this time. Looks like you will have to wait several months to return to Thailand I'm afraid.
I'm confused as to why you would book when you will be refused entry....... can you share if you have a valid work permit and all paperwork as if not thus seems a senseless post 🤔
I dont think they will extend it and they will gave to reapply but talk to the Embassy. They should have still gone to UK now as flights still leaving for UK although I'm not sure if UK borders are open to non UK citizens
If it was like that all the time they would close it down. It is normally particularly busy but ive never been to one anywhere in the world that isnt to be honest.
Hopefully it will be similar tomorrow when I go to change my tourist visa to a Non-O. Im confident I have all my paperwork but not 100% convinced the TM30 I was given is actually a TM30 but im sure I'll find out tomorrow.
