Hello-
As a US citizen I intend to get a one-year multiple entry visa for Vietnam. I am aware that I will have to leave the country every three months. Can I simply do an immediate turnaround and return to Vietnam on the same day I depart. For Instance, can I fly from Da Nang to Bangkok in the morning and return in the afternoon of the same day. I ask this because some countries require that you be out of the country for a certain period of time before returning.
Thank You! D~
