is the last immigration officer told you that you need a visa next time or you won’t be allowed to enter, I would probably pay the 40 bucks (or whatever it costs) and just get the visa.
which embassy in Europe you applying through? Most require you to be a resident of that country to apply for a Thai visa. What is your passport nationality?
Anonymous participant sounds like everything was correct. How long was the 500K in the account? Were you previously in Thailand? If so, what type of visa and did you cancel it?
Anonymous participant 711 this is from the Philippines. It says 3 months of bank statements and then 500,000, but not fully clear in saying you need 500k for all 3 months
