You will have arrived on no visa at all but on visa exempt and been given a 60day stamp which you'll have extended for 30 days at immigration, you may have done a border run for another 60 days visa exempt. 90 day reporting is only required when you have stayed in the country for 90 or more consecutive days. If you leave at 89 days the clock resets no reporting. So when you arrive on 60 + 30 you actually only have a stmp for 89 days so no reporting

If you are entering thailand on visa exempt, 60 days or a tourist visa 60 days then normally it is your flight ✈️ conpany that want to see an onward ticket flight or train etc. Out of thailand as its there responsibility if the thai authorities dont allow you to enter to return you to your departing country. So suggest you check with the flight company. The thai authorities dont normally look to see your return ticket although can ask if they want to. If you arrive on a non O visa then you dont need to show onward travel as its deemed a long term visa rather than a tourist visa

All online. The London embassy is pretty quick for a visa turnaround if yiu have submitted all the correct supporting documents, although they state to expect 2 working weeks. Are you applying via a soft power? If so you will need the documents from them saying you have booked onto.an appropriate course or if medical treatment then an approved plan

not that i have seen, I think there is a Facebook group that has more details of DTV application/ successes

The DTV details are on the thai embassy E visa website. The only soft power activities than can be used for a DTV are Muay thai, hospital or dental treatment plan and a cooking class. These all need to be for a reasonable period of time ~ 6 months and the provider needs to be accredited so they can provide documentation that is acceptable to the thai authorities. Learning thai language is not one of those activities that is accepted by the DTV

The 800k baht is for each of you and in accounts in your own name

If you apply for the non o over 50 retirement visa in your home country then this will make it easier to open a bank account and it doesn't require compulsory health insurance. You get 60days visa exempt if you are from one of the named countries. I would suggest you have non o each before you enter thailand

@Julie *********

you haven't lost any of the visa, you get 3 months to use it. When you arrive anytime within those 3 months you'll get stamped in for the visa duration

@Billy ********

you always get 3 months to activate the visa

@Paul *******
