I would put money on the 30 day visa exempt returning as soon as the authorities have confidence in a Covid vaccine.
They have also done well, in theory, with the introduction of the STV. 90+90+90 is a good visa offering....... the devil is obviously in the detail but the idea is sound.
I can understand that your opinion will be coloured by recent experiences. Something of a piss up in a brewery situation. I am not sure if I previously asked this question but could your difficulties have been avoided by converting your Non O to a 12 month extension, based on marriage, with a reentry permit in place to cover your return. I appreciate that the obstacles of the CV19 requirements etc would still have needed to be dealt with but I guess you would avoided the whim of any Visa changes.
I don't know - what a pathetic answer - but it is now actually the case. My 12 months multi-entry non-O had just expired when I left Thailand in June. Therefore I no longer had a current visa to bargain against. That long-standing option was stopped without explanation. Because I had been assured that my Govt Officer Insurance was all I would need anyway I wasn't too worried and did everything for the 12-month O-A, which then got refused because they rejected the Govt Officer Insurance. I got Emirates 31-day Covid cover with the flight booking. The embassy still rejected it because that one wasn't for 12 months, even though I still would have the normal Govt Officer insurance for the remaining 11 months in Thailand.
They told me to change to a single-entry visa 90-day visa and it was accepted, even though I still only had the $100,000 insurance headed paper for 31 days.
I could argue that there was no logic to that approval.
Therefore when you and Nick told me about reports of people having difficulties at immigration, I played safe and got the additional 3-month full insurance, including Covid, via the French April Company because no Thai company would insure someone 76 years old.
But at Bangkok they only looked at the Emirates one, not the April 3-month insurance, nor the Govt Officer insurance, even though I said that I had them.
Therefore It is difficult to know what rules actually get applied and who by.
So I'm now planning to get an extension to my current visa which expires on 31 December, and to do that quickly while I still have current Police clearance, medical, certificate, bank statements, evidence of transfers to Surin etc etc. I have never kept any cash reserves in Thailand and don't intend to do so.
My understanding is that a retirement extension will be easier to obtain than a marriage extension. I need to do more homework on that.
