grw,
Congratulations as you have reached your liberation day – the dream of ever expat here!
As for "the richest country in the world with no internet or phone-in capabilities", didn't you get, while you were here?! A Bedouin based society with an extreme sudden influx of cash - what can you expect in a few decades?

As for leaving procedures, prepare yourself for some difficulties, similar to those when you arrived. I would give my self at least a 2 month period to complete demobilization (cable, elect, water and phone bills, rental contract, car, insurance, moving company, airline tickets and bank).

Try to do all this a few weeks before departure, move to a serviced apartment or similar, to give time for the retained deposits to be returned to you before you leave.

All the best in your new destination (hopefully a better place)!
