huh, ongoing treatment yes. But planned appointments 6 months in the future? Nahhhh, i didn’t and I’ve never heard that before. What embassy asked for that?
The Dutch embassy wanted a letter stating i was authorized to work full time/year around in Thailand.
The 500k should be in a current account in your name to ensure you have funds to cover emergencies you may encounter. It should be immediately liquid/available. They may accept sponsorship letter and bank statements from a legal spouse. Some embassies also demand the balance must have been above 500k equivalent for 3 or 6 months.
Based on your description, it doesn’t sound like you qualify for DTV based on remote work.
