Vietnam visa
approval letter (or
pre-approval letter) is a letter issued by Vietnam Immigration Department
(a Vietnam Government Agency) allows travelers enter and exit Vietnam for a
given time period. With the approval letter, traveler can pick up
visa on arrival at one of international airports in Vietnam (Noi
Bai airport in Hanoi, Tan Son Nhat airport in Ho Chi Minh City and Da Nang
airport in Da Nang City) or
at Vietnam
Embassy/Consulate.
Copy of the same document
will be transmitted to Vietnam immigration checkpoints at International
Airports or Vietnam Embassy/Consulate, so that when the applicant comes, the
Immigration officers will have those documents on hand and will be able to
issue Vietnam entry visa.
Before issuing
an approval letter, the Office checks and screens visa application very
strictly, so there is no case that you will be rejected at Vietnam airport
or Vietnam Embassy/Consulate once you have a visa pre-approval letter in
hand.
