Tourist visa - exit

Hi
When I applied for my three month Vietnam tourist visa in Cambodia the form asked from where I would enter and leave Vietnam. Is it possible to leave from a border post that is different from what I wrote on the application?
I don't see any mention of the place names for either on my visa.

Yes it's possible. As long as you stick to the visa deadline, no problem.

Leave from any designated border ot airport, but don't overstay your visa. Easy peasy.

Thanks guys.
