Just to put my 2 cents in,
Moving to another country to work is hard enough, having done just that myself. However I had a job offer waiting for me there, and the company organised the work visa somewhat in advance. There are lots of err, and wtf when you move out to somewhere you never been before, no friends, no family, no relatives.
No amount of research can prepare you for the actual move, especially if you do not know the lingo. I would not suggest you to do this, especially given that it is Egypt as well. BUT if you want to learn Arabic, why not look at doing one or two terms in a university there as a foreign student learning the local language? University generally offers somewhat safer grounds to retreat to, but you will also get the benefit of being able to explore local areas.
Oh my parents been to Egypt some years ago now, and the amount of begging was terrible they said...
