Hello. Has anyone been approved a Thai Soft Power DTV Visa? In case so, what kind of proof of confirmation to attend the activity (muay thai, massage course etc) have you sent? Do you need to send a one year confirmation? Can be shorter? I understund you have to pay on advance to the gim or school to have the letter... Is it ok with a 1 week sor 15 days course letter? If anyone has done it already i would love to know how it works... Thank you so much!
