Hi, it is not working like that, you don't need to leave Thailand for the extension. You need to leave Thailand after 1 year, this is the maximum time you can stay without leaving the country.
10.000 != 400$ , my good! 10.000 = 298.67$ , I don’t understand what they are doing. It seems like embassies can charge whatever they want, regardless of the rules??
Yes every Thai embassy has their own rules, that's why deal with visas can be a nightmare sometimes. To me , the reason for the rejection was that the broker account, was NOT VALID. As you can imagine, I did not want to move my funds (that day), to make the officer happy, that's why I was rejected.
Your country does nothing to say what Thailand won't or doesn't want mate. Even every Thai embassy has different rules/opinions. I was rejected, maybe with the same documents you won't, who knows 🤔?, I just shared my experience to help others.
Yes my funds was 100% accessible but the "nice" officer in there, did not want to understand my explanations, anyway I got a different solution (I am married with a Thai Citizen), to me it was ok, but many people can have the same issues I had.
