What is the cost of a vietnam travel visa ?

cannot make any sense out of the person on the phone at embassy,
does any one know the cost of getting one via postal option thanks AK

5 dollar G.I. Jo

Don’t bother phoning the embassy, waste of time, nobody ever answers the phone, there’s a downloadable form on their website £38 – just check out the companies that deal with getting visas but they add on an admin fee – plus a small cost for returned recorded delivery, and I think you have to send postal orders too, I sent mine recorded delivery just to make sure, came back within 10 days … you’ll love Vietnam!

when i was planning to go it cost $70 us dollars, and you will probably need to pay in dollars. I didnt bother in the end as thailand you dont need a visa, and i had already spent $35 getting into cambodia, which is alot more that i was living on at the time.
