wow, that's wild, all I knew about Vietnam was what I watched in movies and what I was told by my friends when I was working for the VA. Then my first trip was over 8 years ago and I applied for the visa when I got there, then last year I booked a hotel for a week, gonna visit a friend in Saigon and I didn't know they changed the rules and I forfeited everything, air fare, hotel, visa fees because I found out on Friday night and was leaving for Vietnam from bkk on Sunday, I massively screwed up, went to the airport and no go, so I bought tix to Cambodia and did the temple's again.
Lesson learned the hard expensive way.
If you need a visa to get into Vietnam,, e visa is 3 to 5 working days if you filled everything out correctly.
I tried to get on a plane from bkk to Vietnam and I didn't have a visa, they wouldn't let me on the plane, this was in October of Last year and I had a US passport.
So I went to Cambodia where I got a visa at the airport.
Vietnam you need an e visa I'm pretty sure. Takes about 3 to 5 working days if you fill it out correctly.
