What should I include for occupation and income on the DTV visa application if I have no current income but sufficient savings?

There are conflicting messages about this issue between applicants, agents, embassies and mouthpieces on FB (including me).

The official requirement is only for the 500k THB in a bank account for more than 3 months.

In theory you can put Unemployed / self employed with no income in that section and it won't affect your application.

But other people say it's critical to prove that you can support yourself for 5 years, even on a soft power, and even though the 'rules' say you don't have to.

Your best option - if it can be done easily - is to visit the Thai embassy in person and ask this question expressly. Write notes and mark the official's name, date you met with them, etc. Then do your online application based on their advice. While you're there you can ask them to look at your support documents and see if they're OK.

If you then still get rejected, it was probably something else.
