I have applied twice at the Thai embassy in Tokyo(first time offline last year before they started accepting online applications and 2nd time online).
First time: they rejected me and refunded me
Second time: they rejected my application DTV after some brutal interview by 3 ladies (2 Thai and 1 Japanese woman).
As far as I know from my experience and from my friends’, I can tell you
1. They are very likely to cancel your DTV application and give you a multi entry TR visa or any other visa they think sites you more
2. Don’t apply in Japan.
3. They will ask you “if your DTV application is rejected, would you want a tr visa?”. I’d you say yes, you will 100% get a tr visa. If you say no, you might be lucky to get a DTV like Mr. ウィール once got.
4. They also asked me and my friends if they have paid tax last year (if you start your digital nomad career from this year or you are relatively new and not paid tax last year in Japan, they will very much reject you or cancel your visa)
5. But don’t worry. You can still cancel your tr visa immediately after being issued. Just email them or visit the embassy to cancel. Because with a tr visa valid, you cannot technically / theoretically cannot apply for DTV.
