After you apply for a Vietnam visa on arrival with us, your Vietnam visa will be issued with validity from the entry date to the exit date in your Vietnam visa approval letter. You’re allowed to enter any time in your visa validity as long as exit Vietnam before or on the exit date.
In some cases, your entry date is changed due to some reason our of your control.  You can enter later than the entry date on your visa as normal, but not earlier.
If you want to enter earlier than the entry date in your Vietnam visa approval letter, you need to contact us to re-process a visa for you with a new entry date. Please contact us as soon as possible so we can support you accordingly in time.
On the other hand, your Vietnam trip is later than expected, you can use the same Vietnam visa approval letter to enter Vietnam as long as it’s still valid. However, you still need to inform us of your exact flight details if you book Fast Track/Car Pick Up service so we can arrange for you on time.
