Check out if you need an eTA to travel to Vietnam
Many visitors do not need a visa to visit Vietnam and are exempt when visiting for holidays or social purposes, however it is really important to check before travelling.
If you are not exempt and do require a visa you will need to get this from your home country before travelling, unless your nationality is offered a visa on arrival, but the Vietnamese High Commission, Embassy, Consulate local to where you live will be able to fully advise you on the current requirements. Do not rely on Trip Advisor for the most up to date information. If you requrie a visa then you must apply before you travel, Vietnam does not offer Visas on Arrival for those that require them.
On arrival if you are from one of the countries that are exempt from requiring a visa you will receive a permit to stay for a defined period depending on your nationality.
Regardless of if you require a visa or are exempt, do remember that you need to have a passport that is valid for 6 months after your departure date, so if you arrive on the 1st of the month and leave on the 30th of the month, the passport should be valid for 6 months from the 30th of the month. If you passport is not fully valid your airline may not allow you to board and the immigration authority will not permit you to land in Vietnam.
There are no longer arrival cards to complete. The immigration officer will issue a permit to stay depending on your passport / nationality after taking your fingerprint.
