Yes you need a visa to enter Vietnam. You need to apply at the embassies or on the net. There are many agencies, but try to find one that have Private visa on Arrival. It is a pre-arranged visa. One of the site is http://www.starvietnamvisa.com . It is much cheaper and faster than applying at the embassies. I would recommend you to do that.
For the others you can try too look up on Wiki http://en.wikipedia.org/wiki/Visa_requirements_for_British_nationals over 6 years agoAnswered by Tna via WorldNomads.com
Yes to Laos and Vietnam, Cambodia you can get a tourist visa on arrival. (30days).
Easier (and cheaper) to organise your visas before you depart (Laos, Vietnam). There are some local agencies who can arrange it for you, but means having them take your passport away for a while (up to a few days) and paying double the price. I tend to be a bit wary of those practices. over 6 years ago
