In general, you will have to submit your application, passport along with two standard passport photos, and the required fee to apply for a visa. Different embassies and consulates will have different procedures - you can check what you need by visiting local Embassy website.

Another option for those who are rushed for time or do not want to send the passport away is to pre-arrange a visa on arrival. This can be done online via a number of private companies who have agreements with the Vietnamese government to collect passport details and arrange for an "approval letter". This letter allows you to board a flight into Vietnam and you will receive the visa stamp upon entry to Vietnam Airport.
These agencies charge a small fee for their service and in most case, the total works out to be equal or less than the amount charged by Vietnamese embassies and consulates. It must also be noted that visa-on-arrival works only for visitors arriving in Vietnam by air.
