Recently had my DTV Approved at Thai Consulate Ho Chi Minh City.
New Zealand Passport
Bank statement was just a printout of my online banking.
The proof of funds money was deposited just a few days before applying.
I also got my dad to write a letter saying that he was willing and able to to support me if I ran out of money. But no screenshots of his bank or anything like that.
I included a copy of my work contract which was from a US company. It was not verified by embassy as some places suggest is required.
Proof of address was just a reservation printout from the hotel I was staying in Vietnam.
Overall it was a far smoother process than I had been led to believe. No documents needed verified from respective embassies, and no issues applying from Vietnam as a New Zealand Citizen on a tourist visa.
Staff were friendly and did a quick check over all my documents before taking my money ($340 USD, no bent or folded notes).
My application was processed in 2 days.
Can't guarantee your experience will be the same, but overall I highly recommend Ho Chi Minh City if you are currently in Thailand and looking to do a visa run somewhere to apply for DTV.
My experience went far smoother than I had anticipated.
