The Vietnam visa stamp can be obtained upon arrival at one of the international airports in Vietnam, including Noi Bai (Hanoi), Tan Son Nhat (Ho Chi Minh City), and Da Nang (Da Nang City).
To get the visa stamp, you need to have already applied for and received an approval letter from the Vietnam Immigration Department or a trusted visa agency. When you arrive at the airport, you will need to present your approval letter, a valid national passport, and a completed entry and exit form, along with any required fees. After processing your documents, the immigration officer will affix the visa stamp to your passport.
Kindly bring enough of the required documents for your entry procedures such as a valid national passport and your Vietnam visa. Your entry can be denied if you forget these documentation requirements. Have a good trip!
