After purchase of this service, our provider will request your traveler information (name, passport number, etc.) in order to process and provide to you the visa authorization letter electronically via email. It is important that you print this out and bring it with you to Vietnam. Upon arrival at the airport, you will show this letter at immigration and proceed to pay the authorization stamp fee. This fee is around USD 25/pax and is separate from the visa authorization letter fee, so please be sure to enough cash on hand to ensure a smooth experience (exact change is strongly recommended). Please also remember to carry at least 1 headshot photo (4*6cm) for this process. In the event you misplace this photo, you will still be able to take a new photo at immigration (additional fees would apply). Approximate waiting time for this visa procedure is approximately 15-60 mins depending on the on the number of immigration staff present and arriving passengers. The visa authorization letter process itself will take 4-7 days to process, so please plan accordingly.
