We are flying into Hanoi and then down to Ho Chi Minh and onto Phu Quoc for 3 days then back to Ho Chi Minh to fly back to Australia. Do we need a multi entry visa for this or a single visa is enough? Thanks for any help!
You will be travelling from Hanoi to Ho Chi Minh City and Phu Quoc, all these places are inside Vietnam’s territory that you will need a single entry visa. Multiple entry visa is required if you are entering Vietnam more than once (first entering Vietnam then Laos and return to Vietnam finally, for example)!
