I ran into an American expat in Jeddah in 2000 during Hajj. He started in the early 80s late 70s. He went with a family with the intention of returning home in 5 years and buying the dream home etc etc. 5 years later the family went home, he stayed. Only Saudi MGT, Techs were still imported from mostly Europe, he was the only remining one from the USA. That is a long time to live in Rose City.
