i came there at around 1 pm, does not have to be early..its just the border, just crossing the bridge. You go there, there are many foreigners going in and out everyday. They take your passport and on the way back they give it back. Easy :) you will see everything when u arrive. Is not long, is not really a process. You just give them passport, pay 500 baht and thats it.
