My boss I mean my sponsor he is very rich but he is very poor in practice his words,
My case is I came to qatar in 2006 and worked untill 2008 sep.while this period I have tendered my resignation three times but they allaow me to go only at third time at that time I have lost all the opertunities that I got from other countries eventhough I can'n sit without income so I went to Oman and after one year I got an good oppertunuty from qatar but I was not able to join with them without a NOC so I compelled to contact my old employer in qatar for NOC at that time he replyed that it is not possible a NOC but we are inneed of ur service and we will give you good package and my position will be the site manager instead of site engineer when I was in qatar, but when I joined back with them they were not ready to practice their offers. i am getting my salary exactly but in the case of family I am not able to bring them here as my profession is some technical concern.

So in this interim changing of sponsorship system in essencial then they cannot cheat anybody.
