I'm confused first you say you are a refugee in Germany. Then in a later comment you say you are in Iran. If there is a Thai Embassy in Iran you need to go to their website and see what visa you qualify for.
I agree I am referring about people who asked for like a one day or two day class. Yes I know it is a new type visa but you have to be realistic. If they want to apply then I wish them success.
but the question is what is the medical appointment for? A long term medical problem with multiple follow-ups and treatments. I seriously doubt they got a 5 year visa for a migraine or because they stubbed their toe.
You do not have to be an experienced traveler to know you won't get a five year visa for a one week course. Common sense tells me this. If anyone gets a DTV for something like that I will apologize.
