I have exited and re entered many times during the year. Of course I have the money 🤷🏻 untouched, but they have ever asked me anything. Remote worker, not soft power, if that matter.
For soft power or workcation? I think that using an sponsorship for a workcation would be odd, as you're supposed to be a remote worker. For soft power it might be understandable. Of course what I think doesn't matter, but what I'm saying is that the Embassy can see it this way.
The visa is a PDF file, BTW never ever believe ChatGPT for serious things as visas, taxes, laws... Whether you can apply in Spain or Portugal will depend on whether the Thai embassies there accept applications from tourists or only from national/residents. You need to directly enquire with them. Many Thai embassies in Europe won't accept application from tourists, meaning you don't have an official residence status in that country.
currently they hold Dutch passport, yes. It doesn't mean they're not half-Thai, as their father is a Thai. They can easily get their Thai passport also.
no, you can't, unless you lie and/or F o r G e documents. The reason: the embassies demand that your intented entry date be within 3 months from the application date. If you're planning to come in January, you'll be able to apply by October. But, if you apply would it be trhu workcation or soft power? I ask because most embassies won't accept Thai language courses to issue a soft power DTV.
