When you apply for a Vietnam landing visa through the Visa on Arrival program, the following are the costs applicable:
Service Fee: You will pay a service fee levied by the agency at the time of your online application. This fee will vary depending on the type of visa you apply, as well as your citizenship. Once the payment is successful, your application will be processed.
Stamping Fee: Stamping fee is the official fee charged by the government to issue your visa. When you arrive at the Saigon airport, you should be paying this fee in cash at the landing visa desk to collect your visa.
