hello,
i visit vietnam every year and I know the system very well. As you have been told in the other replies you can apply for a letter though your travel agent to get a visa on arrival at the airport in Vietnam. Depending on how busy the VISA desk is on arrival you may be waiting for over an hour, i got back last week and a friend had a "letter" she had to wait 90 minutes for the visa to be issued.
Save time and apply for a visa before you go, it is a simple process and you will be through immigration and customs in no time.
If you like waiting around then go the letter option
