I will probably be traveling into Vietnam by bus from Nanning to Hanoi. Can I get a visa when I get off the bus if I have applied on line first and received my approval letter? If not what is the best way to get the visa?
Be kindly informed that Visa on arrival is only applied for those who travel by air to Vietnam. If you go to Vietnam by bus, the only way to get Vietnam visa is to contact the Embassy/Consulate in your place for visa application.
Wish you all good things,
