@Robert *****

you're wrong. A non-O visa from London doesn't require any insurance.

Business as usual

The only "benefit" to using this service is the appointment. But you can make an appointment for free, so there's not actually any benefit to using this service. And you get to pay extra for it too.

So you submit all the required documents online. Then you must bring all of those documents with you to the immigration to get your extension stamp. It will be a 30 day tourism extension, it will not be 60 days, or any other number than 30. All tourism extensions are 30 days.

Maybe this will stop them from collecting the 20 baht "exit fee" (yeah right 😂)

It's what I would do. If you arrive visa exempt there is nothing to do ahead of time except filling out your TDAC.

The odds of immigration asking to see proof of onward travel are very low. It's more likely the airline would ask for that before letting you check-in. But they can ask for that on a tourist visa as well, since both visa exempt and tourist visa are both tourist entries. (Though to be fair, the odds are lower if you have a tourist visa).

@Justen *******

there's a specific list of things they're looking for. 5 or 6 of them. They are all disqualifying. The form is on the embassy website.

But most people don't want that visa. If you start with a non-OA and intend on moving to Thailand permanently, you're going to have to purchase the mandatory insurance every year, forever. And it's only going to get more and more expensive as you get older. There's absolutely zero advantage to getting a non-OA visa if you're planning on moving to Thailand. You should be getting a non-O if that's the case.

@Hardev ******

Which visa you gets depends on which one you applied for.

Non-O is a 90-day single entry visa with very easy requirements.

Non-OA is a 1-year multiple entry visa with much higher requirements, including mandatory insurance, health check, background check, etc.

Just pretend it's not there. Sponsor letter is mostly for family members.

What is your actual question? Ask that. Because if someone comes here and just says "yes" that answers your question but doesn't help you. So ask what you actually want to know and save everyone time.

There's no such thing as a non-immigrant multiple entry visa, especially not one that's valid for 6 months. There's a multiple entry TOURIST visa that is valid for 6 months.

The embassies have not sold multiple entry non-immigrant visas for more than a year at most embassies. Non-immigrant visas are only available in single-entry 90 days.

Or you can just go without a visa and enter visa exempt and receive 60 days, apply for a 30 day extension. Then do a border bounce and get another 60 days and extend for 30 days. This is the exact same thing you would have to do with the multiple entry tourist visa, except you don't have to pay $325 per person.
