How long do I have to stay outside of Vietnam before re-entering?

Question

If I visit Vietnam for 90 days on a 90 days tourist visa and exit Vietnam as required at the end of 90 days, how long do I have to stay out of Vietnam before I can reenter?

Answer

If you have a valid visa for Vietnam for the return, you can re-enter the country on the same day after your exit. However, it is not possible to apply for a Vietnam e-visa if you are staying inside of Vietnam. So that you have to leave the country and stay outside of Vietnam for a few days waiting for visa approval or apply for a rush Vietnam e-visa to re-enter on the same day.
