one more thing I just though of, about the language barrier. I was saying that I have no problems but that could be just me and my limited experience here.I am given to understand that there will be a lot of difficulty at govt depts if you don't speak Arabic. Getting your message across can be problematic.

You didn't say what you'll be doing over here, whether you are an entrepreneur and as such, will need to do a lot of running around and sorting things out by yourself. If you are with an established company or one which has been here for a few years and learned their lessons the hard way, then you'd have less to worry about. I wouldn't say nothing to worry about.. but less.
