When you land at an Vietnam international airport, the first thing you see (often before or right beside the Custom area) will be the Immigration office with the bright sight showing “visa on arrival” or “landing visa” what you need to do is coming there, handing your approval letter in at the Immigration desk and fill in a simple form. Please remember to bring at least 2 passport-sized photos (4x6cm), pay 25 USD for stamping fee/each person for single entry visa or 50 USD for stamping fee/each person for multiple entry visa, wait about 15 minutes and finally, you can get your visa stamp upon arrival.
Please notice that at present, there are three international airports in Vietnam, they are: Noi Bai International Airport (Ha Noi), Tan Son Nhat International Airport (Ho Chi Minh city) and Da Nang International Airport.
