It has changed recently but I believe it's 3 months prior (and 2 months post). Bear in mind that it will take some time to open an account, which can be tricky (but not impossible) with an O visa.

If you can get a retirement visa in your home country it can be better because you don’t need the funds to be ‘seasoned’ in Thai Bank account, just in your home account. But it is possible and quite easy to do in Thailand too (through seasoning).

Not sure. Mine was in English. The school or place you are going to teach should be able to advise. Or immigration, or your Embassy (if they will notarise, many won’t).

No just the degree certificate

David Broadfoot yeah, you’re right. I was thinking of the requirements to get a visa not visa exempt. Might be difficult now though with travel so restricted. Main point for OP though is when using visa exempt I’ve always been asked to show proof of return, (at Heathrow anyway).

David Broadfoot yes, but ‘on the day’ tickets are usually v expensive if you don’t get an even more expensive refundable one. And the visa stipulation is return to home country not a cheap flight to KL or something. One way to do it buy refundable Expedia flight originally, print that off as evidence, get a refund and buy a one way. I haven’t experienced anyone who had their flight checked online at the airport.

I have absolutely no idea. I’m just speaking from my experience. The OP can use their own judgment about whether to risk it. I certainly wouldn’t.

@Prieto ***

the OP says he might want to stay on for ‘teaching or educational purposes’. He would not be able to, for eg, change STV for education visa

You almost certainly would not have been allowed to board without a return ticket planning to do a visa exempt at Heathrow by just saying you hadn't finalized your plans yets. Airlines can be fined for that. And I've flown several times a year to Thailand over the last 6 years. I even had my return ticket scrutinized pretty thoroughly, it certainly wasn't a quick glance.

If you have a visa you are not usually asked by the airline (because they presume this has been done as part of the application) but if you plan to travel on Visa exemption, you are very likey to be asked - I always have been when traveling from the UK
