My family (all UK passport holders) are planning to travel to Vietnam in April. Can we apply for the visa approval letter now? How long is it valid? Andy
Be kindly informed that your visa approval letter will be valid from your granted arrival date to your actual arrival date no matter how long in advance you apply and receive it. So, you can apply for a visa approval letter right now or later. However, we advise you to make the application at least 2 weeks in advance to avoid any unexpected problems.
Wish you a good time in Vietnam,
