Is Visa on Arrival legitimated? Yes. Visa on Arrival is legitimated by the Visa Vietnam Department which comes under the Vietnam Government. Visa on Arrival is a much more convenient process and it is being preferred by most travellers these days. Usually, there are two methods by which a foreign citizen can obtain Visa. He can either contact the Embassy of Vietnam in his country or apply for Visa on Arrival. The embassy method is long, time taking and expensive. 

In order to apply for Visa through the embassy, you will have to personally visit the embassy. This can be a problem for those who reside in areas far away from the embassy location. At the embassy, you will be required to fill the Visa application form. Along with the form, you will have to submit one recent passport sized photograph, one self-addressed envelope and your original passport. Your passport must have a validity of at least six months and a few blank pages for stamping purposes.
