BELOW WAS THE POST I READ FROM A LADY WHO HAS DONE SOME DIGGING.
DTV Application Embassy Hanoi:
Got an email with the answers to my questions. I own a company so didn't ask how it works with employment contracts. I also did NOT ask about the funds because thats obvious to me how to proof that.
1. Visa processing time approx. 3 working days
2. notarised company registration papers as proof of work
3. document that shows booked doctor appointment
(asked about soft power as well)
4. visa stamp in passport accepted as proof of location
If anyone applies in the next weeks or months, I'd love to hear how it went. Planning on going to Hanoi mid November.
