What are the qualifications and requirements for the DTV Visa, particularly regarding the ฿500,000 funds and application options like 'workation' or 'freelancer'?

Hi everyone, this is kind of a long question so please excuse me.

I wanted to clarify the qualifications of the DTV Visa. I would be applying for that in Taiwan, which is where I’m currently living at. In fact, I heard the embassy here is rather smooth and easy to deal with compared to other places.

What I particularly wanted to ask about was the ฿500,000 qualification. I’m not sure whether it makes a big difference which option to check between “workation” or “freelancer”, is one option easier to use than the other?

Also, when it comes to proving that you have the ฿500,000 does it matter how long it’s been in the account? In other words, if I just transferred it, and it shows that it’s been in the account for just a day or two, would they give me a hard time?

How strict are they when it comes to proving that you work as a freelancer? In my case, I would be doing private tutoring online, in addition to investments, but I’m not sure if they care about how much you’re bringing in per month for that job, or they only care to see if you’re working at all? If they don’t care, then I guess all I would need is proof that I’m working for that employer?

Sorry for the long question, and thanks in advance!
