just tell them DTV it's enough, they can see it on their screen once they scan your passport. Always check your stamp when they hand back your passport
Anonymous participant Noted. With the booking school how did you apply, direct with them, presumably they are genuine, have you checked they are one of the official accredited schools under the DTV. Otherwise you just have to enter the details as shown on your passport. Did you submit every page (including blank pages) of your passport in a pdf file, i used IlovePDF app to compressed the pdf file etc. Otherwise check all other details were entered correctly. Sorry other than that I can't really suggest anything else GL
Everything looks fine, do you have any current or previous criminal records. Have you been a frequent visitor to Thailand, have you ever over stayed?
Also check your application in case you didn’t put your name in full as shown on your passport, check date of birth etc, check all the info provided. How many years on your current passport do you have left etc
Otherwise it’s difficult to know why you were rejected?
You applied for soft option ie. 1 month Muay Thai, definitely needs to be longer 6 months but on the other hand you say you are freelancing, money coming in, what exactly is your work, why didn’t you apply for workcation category?
