Applied for DTV Visa in Ho Chi Minh City, Vietnam on 10/13. Additional documentation requested on 10/16 (more bank statements & more recent/clear photo) - submitted these “additional” documents that same afternoon. Vis approval received 10/21.
Just have all of the required documents organized and available, feel free to submit any additional documentation that you feel may help your consideration & give them time to process.
Very straightforward process & was handled in what I feel to be a timely manner. Good luck! 🎊🍀
*SN - the additional documentation requested was already included in my original application submission. I included (in my original submission) 3 months of bank statements and a passport image I had taken just a month ago - so when they asked for more, I got a little worried, but just took it in stride. I sent in a screenshot of my current bank account balance + the most recent bank statement (reflecting the required 500,000 baht) & took a “passport style “ selfie right then and there and submitted these as my additional documentation. Worked out well for me, although this may not be everyone’s experience.
Just be well prepared, is my only advice.
