Is there something stopping him from registering as a patient at the hospital and then receiving the documentation? Is the issue that he needs to DTV to enter Thailand at all based on his nationality?
I don't know why the medical provider would be in the position to determine eligibility for a visa. They can decide what treatment you need and it would be up to the embassy to decide this based on the facts, no? Are they refusing treatment because you're not on a proper visa yet?
Anonymous participant I have a hyphen in my first given name as well, and when the system captured it, and it's displayed differently on the biographical page on the passport. In the MRZ (machine-readable zone), it omits the hyphen, but my full name above shows it. The OCR in the e-visa application system separated my first name into first and middle incorrectly and left out the middle name. I corrected the first name but didn't input my middle name. Didn't think omissions of non-essential (in some cases) parts of your name were errors. Actually didn't think my middle name is important for a visa. So, yeah, I got rejected but ended up getting accepted later. I also don't agree with it, and it isn't common to take large application fees for minor errors in other countries, despite the vigorous defense this topic seems to provoke here.
Anonymous participant 561 I know, let's get over the idea that it's just fabrication. And why don't people just invent these false stories about Bangkok then, not just Chiang Mai?
I haven't seen any reports of USA consulates requesting interviews. This is more common in SEA consulates. Just speculating, but maybe it has something to do with the wide areas of the consular jurisdictions.
Just a drop in the bucket, tourism-wise. Strange that they would bother focusing on stamping out visa "fraud" with extra border checks, like people are reporting. Haven't heard of someone being denied entry on the visa yet though.
