British, German, Norwegian etc. can get the free stamp at airports. What about land borders?

 

Need an urgent confirmation.

 

Thank you in anticipation!

Assuming you are entering from Laos or Cambodia, I believe that you need a letter from the Vietnamese embassy in one of those two countries.

You can get the 15 day exemption at land borders as well. What doesn't work at land borders is the VOA, so the confirmation letter you are considering  is useless there. In theory, you need to have a confirmed flight out of Vietnam to qualify for the exemption, regardless of whether you enter overland or by air, but they rarely ask for this anymore. I entered from Laos overland recently and had a flight confirmation ready, but they didn't ask for it, and the talk on the websites here (I moved to Vietnam from Thailand 2 years ago) is that they are not that strict anymore. 

If you qualify for visa exempt entry, then entering at a land border won't be a problem. If you have entered visa exempt before, you will need to stay out for 30 days before you can enter visa exempt again, regardless of the point of entry.
