Once you have your e-visa available, you’ll receive an email to inform you of this. Click on the link from your email and follow the instructions on how to download the e-visa. Once you have downloaded the visa, save copies on your device. Also, print at least two copies so you’ll have a spare copy.
When you arrive in Van Don Airport, go directly to passport control. Give the officer your passport and also your e-visa copy. The officer will verify your visa through your passport. When everything is good, he will stamp it so you can enter Vietnam.
