i posted a question before and wrote passport instead of visa.....oops!! my real question was does anyone know if it's possible to extend your visa once in vietnam because mine is only good for 2 weeks?
Normally ( as I know) your visa must be good valid at least 1 month before u wanna extend it. I think you should get a new visa!
Tourist Visa extensions cost around US $ 20 , but it is easier to pay more and sort this out through a travel agency. The procedure takes two or three days and you can only extend one time for 30 days
In theory you should be able to extend your visa in any provincial capital. In the practice is goes smoothest in the major cities, such as , Hanoi, Hochiminh, Hue, Danang
