Djpekingman buses will be managed DJ.
They have special dispensation. I suspect they'll be an agent who will take the passports and do the shitty queuing.
If its a decent VIP style bus you might just chill in convenience.
At worst you will get off and hand in your passport and visa info at the Cambodian side and wait a little in the heat.
It's not 100% obvious what you do so follow everyones else lead.
I didnt arrange a visa and had to walk over. Hence all the hassle.
I went over with a Slovenian, a Philippino and a Vietnamese lad who I work with.
They saw a collection of odd passports and decided to take the piss.
