I went there today for my 90 day report, arrived just after 8.30 and was out after 2 and a half hours. Just enjoy the little food market they have and have some breakfast, makes the waiting a lot more bearable.
Search for my report of my application in HCMC, I was in similar situation and included a cover letter explaining the situation and included the signed contract of the job which was still to start. I was approved.
You booked a 1-week trip to apply for the DTV? Vietnam gives a 90-day tourist e-visa. I can only wonder why you this to yourself. The application takes 5-10 working days. If they ask for further documents, the clock resets to 5-10 working days. You should have planned accordingly.
That is not nonsense, it's nothing but your opinion. One of the categories of the DTV is about Thai culture. Thai food definitely falls under that. Might be problematic for extension but let's just live and let live.
I haven't even started yet, not thinking about what might be. I am assuming I'll continue Muay Thai as a means of keeping fit and learning some skills. If, I do not continue and it becomes an issue and they cancel my DTV, what I do not expect, I am sure I can then apply as freelancer. But I do not see a reason to worry about that today, it's my first day back in bkk and finding a nice condo has more priority in my head.
