I'd definitely start with an extended vacation. Make sure u like it here. it is quite different from the states. Much free-er, disorganized, inefficient yet fun!
lebs are super receptive to americans and europeans, as far as my experience.
Cost of living: double the states! clothes, beauty/health products, drugs, vehicles, and pretty much all tangible goods are imported, hence overpriced. Food is a toss: small box of Corn Flakes: $6; local Zaatar (thyme based sandwich) served fresh and hot: $1.
good luck!
