I picked up my Thailand visa today. I wanted a double or triple entry visa but forgot to specify this in my application. This is my first visa ever and thus a rookie mistake. I told the lady who gave me my visa that I had made a mistake and asked how I could get a double instead. She was of zero help unfortunately and said maybe next time.
But I know there is a way! Any help is greatly appreciated. I fly out on Friday, July 3 so my time is kind of limited although I can apply for a visa and pick it up just 2 days later.
