I have apply my Vietnam visa on arrival with www.visa-vietnam.org.vn and i have received Perfect service. The first thing make me feel so satisfaction is about the customer service department was so good, those staff able to answer and explain all my question and request. They also provide extra service to make customer feel more comfortable for those customer come Vietnam for first time or dont want to lost time waiting on the long queue. Everything was so perfect that make me feel good for my trip. For sure i will apply for this service again with my next Vietnam trip and introduction this service to my friend and company
