Quick Vietnam Visa 
What if I change date after I got my visa on arrival to Viet nam?
It is no problem if that date is after your proposal date and within the validity date of approval letter that you are accepted to enter Vietnam. If not you are required to apply for the new approval letter with your new arrival date.
