Should be fine. No minimum income is asked. Just the at least 500k THB in savings + a work contract mentioning you are free to work remotely from Thailand / or a company registered in your name.
Good question. Still not fully clear. It seems that some consulates in 3rd / neighboring countries do accept applications from foreigners / non-residents, others donât. I have yet to see / hear of the first success story of someone successfully having gotten a paper sticker DTV in Laos, Malaysia, Cambodia, or Vietnam. Maybe this question will be answered in a few days when people report their experiences.
Either proof of a registered company in your name, or a current letter from an employer stating the freedom to work remotely from Thailand seem to be the most commonly accepted ways so far.
They used to actually ask for proof of a booked flight by means of an uploaded ticket. Now, with the DTV, there is no such upload requested anymore in the eVisa system. You still have to fill in a flight number in the form, though. I guess they just re-used the same web form. You could try and just submit a flight number of a flight you aim at taking, imho. Good chance they wonât ask for additional proof. Some consulates might however still request such proof - I guess to ensure that one is actually applying with the ârightâ consulate in the country one is flying to Thailand from.
