Good Morning Steve,
I am pleased to inform you that both dates have been given the green light.
Until 30 June 2017 ‘British Citizen’ passport holders travelling for tourism or business can enter Vietnam for up to a maximum of 15 days without a visa. If you have a different type of British nationality – for example ‘British national (overseas)’- you’ll need to get a visa before entering Vietnam.
Kind Regards,
Mildred.
