Some of the appointment letters were a little vague, so I just explained what exactly the treatment is and tests involved. I praised Thailand’s medical facilities and doctors based on my own past experience. That I planned to immerse myself in Thailand’s culture through my activities, which I believed was MoFA’s purpose for creating DTV. The letter was detailed but concise and non-condescending. I kindly asked to be granted DTV and thanked the embassy for the opportunity.
