Also if I am leaving the country and coming back in, do I need to get any type of stamp in my passport to not mess up the DTV?
(For example if you have a visa for the country but you don’t get your exit stamp or the other one which allows you to go away and come back in again without issue - do I need to do the same for the DTV?)
so you can stay in another town? It doesn’t need to be Hanoi or Ho Chi Minh? (Do a lot of people get requested for interview? I’m on crutches so probably best to stay in Hanoi or Ho Chi Minh?)
