There is a large customer-service counter along one wall of this cavernous room.  There are about twenty or so workstations set up behind it, a dozen of which are active.  There is a long line of people by each work-station.  On another wall is a large reader board:<br/><br/><div align="center">Welcome to Al Amarja Customs and Immigration<br/><div>Please Do Not Panic.</div>Now serving:<br/><br/>1102<br/>2301<br/>2518</div><br/>There are a number of doors in the wall underneath the reader board and a man standing next to a turnstile, almost like an usher in a movie theater.  How very odd!<br/><br/>Getting in one of those lines would probably be the appropriate thing to do.  A fair guesstimate of the wait time is probably around half an hour for any of them--the lines are pretty evenly spaced and seem to move with a fair amount of efficiency.
