The first thing you have to do is find out the Vietnam embassy or consulate address in your nation. If your current living nation doesn’t have Vietnam embassy or consulate, you need to go to the nearest nation having them to do this process. This way helps you surely to hold your visa before you come to Vietnam, but it takes a lot of time for processing (it normally takes about 5 – 7 working days to get the result) as well as it wastes your effort and time, especially in case the embassy or consulate is far away from your home.
