Almost all the accounts of having trouble on entry are from travelers arriving in Chiang Mai. I have a theory that most of them have recently received DTVs in Vietnam and are entering Chiang Mai for the first time. At this point, there aren't enough reports from DTV holdersto confirm commonalities.

Well, this data's incomplete until we have a report on entering Chiang Mai.

I'm not familiar with the House of Taste specifically, and you might have better luck at other embassies. Also, even if there have been success stories with this school, some of them might just be marketing from the school. Did you happen to see the recent post in this group from someone who visited this school in Bangkok?

Hi OP, I checked the House of Taste website. I see you chose the DTV course option. You might have thought that this designation legitimized your choice, but it actually does the opposite. Some applicants have been rejected specifically for course enrollments that suggest are specifically for the DTV. Enrolling for a course specifically for the DTV lowers your chances from past cases we've seen in this group.

@Kyoung ****

What did you submit for this requirement?: "English portfolio....providing your life plan"? Did you give an explanation of how you'd support yourself or how you'd occupy yourself in Thailand? That is how I'd interpret this.

It's possible but not guaranteed.

@Greg *******

The requirement for soft power, for most embassies, is an appointment letter, with no guidelines as to format. OP's mistake was asking for a letter for the DTV in his first contact, which now makes the healthcare provider worried about reputation management.

I got a DTV for medical treatment myself, but I didn't involve my care provider in visa issues. The provider says that they only will provide a letter for a DTV for a patient who's only been in their care for over a year among other requirements that the OP can't meet right now. The hospital didn't say that they wouldn't provide any treatment plan at all, just not for DTV applications, which personally I don't think is their call because their expertise is not immigration.

My point is anyway that there's nothing stopping the OP from bypassing their refusal and using other treatment documents they provide, which they could obtain with a medical visa or otherwise.

Also, the hospital's answer specifically relates to patients "eligible to apply for the DTV," not whether they would be able to seek treatment at the hospital.
