kafala system really problem for expats but good for companies.. some companies the small ones.. whose owners are mostly expats asians abuse their employers.. big companies also dont allow their workers to change jobs even working in the same company for 4 years or more.. thats is big issue.. and wont allow you to travel when ever you want .. even if u want to travel for few days u have to beg with your sponsor or employers and always under threat.. cant leave the country ...
