When I went to Morocco in May I landed at the Rabat airport. We walked inside, stood in lines to have passport stamped. Behind the desk was a hallway to the luggage area, and there was another guard or airport worker standing there who asked to see my passport. That's kind of silly because didn't the person at the desk just look at it and stamp it? So anyway, I don't think he actually looked at the passport, but he pulled a yellow card out of it. I think it was laminated.
I don't know what that yellow card was, and I am curious.
Does anybody know?
