Hi, so I several questions about obtaining a Visa in Vietnam. I have read different travel books & different websites. I seem to be getting some conflicting information. When I traveled to Cambodia, I obtained my Visa at the Siem Reap Airport, it was quite easy. It sounds like it is the same in Laos. Now, in Vietnam can I also just get it at the airport when I arrive or do I need to coordinate before hand? Also, I read on a website that when I apply for a visa, I need to provide specific information such as my departure flight from Vietnam. I am planning on backpacking and I don't really have specific time frame right now.
Please advise me on this. Thank you in advance for your help!
