Question 1:

I'm planning my first entry is Ho Chi Ming city and then fly to my second stop at Hanoi. Does it count as single entry into Vietnam? Thanks

Good day to you Eve,

You only need single entry since you enter and exit Vietnam once. In case you enter Vietnam more than once in a period of time(1 month, 3 months), you need ,multiple entry visa. 

One more thing, you need to get stamped visa at the first arrival if you use visa on arrival.

Thank  you so much !
