Aside from the pre-approval letter, there are other requirements that you need to give at the Visa Landing counter and get your visa. So here’s a list of the requirements needed for your Vietnam visa on arrival via Lien Khuong Airport:
- Pre-approval letter – the letter is the most important requirement that you need to submit to get your visa. Also, when you check-in for your flight, some airlines will be asking you for your Vietnam visa. You need to show them the letter because this is proof that you’ll get your visa when you arrive.
- Passport – it’s very important that you have your passport because this is where the visa sticker will be attached. It must be valid for at least 6 months from your date of entry in Vietnam.
- Application form – this is the blank application form that you need to fill out in advance. Vietnamese-visa-application-form (Form NA1)
- Photos – you need to submit photos in 4 x 6 size. It should be taken in a white background. Photo Guide.
- Cash – for the stamping fee, you are required to pay it in cash, either in USD currency or Vietnam dong. It will cost around $25. See Vietnam visa fees update.
