While I've read that only Vietnamese can get a driving license in Vietnam, this seems to be wrong according to a travel agency website.
If you are a tourist's here is where to go
Office of Traffic and Public Works
16 Cao Ba Quat st. Ha Noi
In HCMC
63 Ly Tu Trong Ho Chi Minh City
For residents
Automotive Training and Mechanism
83A Ly Thoung Kiet
Ha Noi
Office of Transportation
63 Ly Tu Trong
Ho Chi Minh City
The cost is $1.5, yes a buck and a half, plus copies of passport, 3 photos, translation and notorization of documents.
Turn around time of 5 days.
Please correct me if I'm wrong, like that wouldn't happen, lol, (just making it easier on the criticizers)
