The counter is located inside immigration Departure Hall 2 i.e. after you have cleared the security check... just take escalator down the hall and you will see is a big board which you can't miss. 1200 Baht for single entry. Takes about 15 mins per passport. Don't need to bring your own photo and form any more, as they use their cameras, the form gets printed and you just sign it
