Dear sir or madam,
as I found on the web site http://www.myvietnamvisa.com/ there is a way to obtain visa to Vietnam on internet. It is easy, conveniant and quick. If I understood it correctly this is the visa to land in Hanoi, Ho Chi Min City or Danang.
Could You, please, tell me if I will be able to use this visa once I will be arriving to Vietnam from Nanning, city in China, by bus?
