FYI. I applied for a Vietnam 30 Day Single Entry Visa today in Bangkok. Drop off your passport at the Vietnam consulate on Wireless Road between 0900-1130. Pickup time is 3 days later between 1600 - 1700. I dropped off my passport on Monday and they said to pick it up on Thursday at 1600. 2,200 Baht. I didn't ask for express service and they didn't mention anything about it. This "normal" service was fine for me. Very simple process and had one person in front of me when I arrived about 1045. The visa form, one photo, 2200 THB and my passport was all that was required from me. USA passport.
