I'm travelling to Vietnam in December and January with my partner. The first time, we will just be passing through on our way to Sydney. We are flying with Vietnam Airlines and our flight has a day's stopover in Ho Chi Minh City (6am-9pm) so we will very briefly enter the country. Then, two weeks later, we plan to visit Vietnam for a week. Could you please advise which visa we need. I have a British passport and my partner has an Australian passport.
At the first time, if you just stay in transit area, you do not need to get the visa. Besides that, UK passport no need to apply the visa if staying within 15 days (The previous visit must be far the next visit 30 days), but Australian passport has to get it.
