I flew into RAK on U2, so pretty different, but I guess this is the best you'll get for now. Morocco has a landing card, but they weren't distributed on the plane. If you don't get the card, try to get off as fast as you can and grab one. Complete it as fast as possible (while in line if you have to). Immigration is closer to EU style in the sense that you're not really asked any questions. they take your landing card, scan your passport, etc, then stamp it. Then in RAK there was a guy at the exit from immigration who just checked for the stamp in your passport lol. Then baggage claim, and customs is again a red/green lane thing
