The TCN's are like illegal immigrants in the US as far as pay, bennies, and social status, except that they are legal in the middle east with tight restrictions.
The TCN (not his family) can typically work for 6-8 months on, then go home for 6 months. They can do this for usually ten years, after which they must go home for good. If they ever return, they are subject to SEVERE penalties, including death in some nations. No Ceaser Chavez rable-rousing in the Kingdom or the Emirates.
