I've got the dates wrong on my Vietnam Visa and I leave in two weeks. So my girlfriend and I have applied for and received our visas from the Vietnamese embassy. Last night I was checking the flights when I found to my horror!! that we'd booked them one day earlier than we had thought. This means the date of arrival on our visas is the 23rd May and we arrive on the 22nd May. Can we enter Vietnam before the approved date?

I am an American. I'm visiting Thailand and I'll be transiting through Vietnam with Vietnam air. I am staying in Thailand for 2 months and on my return, I will also transit through Vietnam. If I would like to get out for some hours, do I need to apply for advance approval letter from vietnam immigration before being grant with a transit visa on arrival?

I’m a Camaroonian, I’m planning trip to Vietnam but  there is no Vietnam representative office in Cameroon at the present. My country is special list of countries to arrange Vietnam visa. So what are there conditions to make Vietnam visa?

I want to go to Vietnam and find opportunities for cooperation. So what kind of visa which I get? And the diffence between business visa and tourist visa?

I'm a bit confused about the cost of ordering a visa by post, coming from the UK. I've visited the embassy website and followed their instructions, as far as I can see, to the letter. I emailed them asking for a price of a 30 day tourist visa + postage, they've responded with a list of costs for various visas, including the one I want, all minus the cost of postage. So i replied and asked again for postage costs, and have had no response. Am I missing something? It definitely says on the site to include a self addressed envelope without the stamp.

Why are postage costs classified information? Has anybody done the same as me recently that could tell me the cost?
