Thought I'd share my DTV process for those who is going medical route in HCMC Vietnam.
-Applied for HCMC Consulate
-Took a day before requesting for documents
-I moved money to personal bank account to be sure (well over the 500k baht since it's joint )
-for documentation of what medical care plan
-I'm an athlete with injuries so I showed diagnosis, MRI's, multiple doctors visits, PT , receipts, and treatment plan over the next few months. (all done at thai hospitals and had wet stamps) Also had a cover letter explaining what each document was.
-they replied and said my bank statement was not correct (which was the only option I had from my bank). so I took a screenshot of the account activities and sent that with the previous bank statements that they said was not a bank statement.
-They followed up and asked for a selfie with the date and my name on the receipt at the location I'm in.
-Approved 3 days later.
I've also found when it asked for help here there were a couple trolls who weren't very knowledgeable and specifically an old guy who was a "top contributor" that sounded adamant I won't get it.
so just be prepared in the requirements and read other stories of what others have submitted.
