There are two types of Vietnam visas on arrival:
- Single-entry visa: This type of visa allows you to enter Vietnam only once during the validity period of the visa. If you leave Vietnam, you will need to apply for a new visa to re-enter the country.
- Multiple-entry visa: This type of visa allows you to enter and exit Vietnam multiple times during the validity period of the visa. This is a good option if you plan to visit neighboring countries and return to Vietnam multiple times during your trip.
Both types of visa on arrival have different validity periods, ranging from 1 month to 1 year. The validity period and visa type you need will depend on your travel plans and the purpose of your visit to Vietnam. It's important to check the requirements for each type of visa and ensure that you apply for the correct one before traveling to Vietnam.
