just to share my experience, after i have signed my job offer, i've waited more than 5 months before i finally joined ictQatar when i was recruited though i was a direct hired..just be patient but be smart also, i have heard that some agencies tries to replace selected candidates in place of their kins/relatives..i wish not in your case.keep in touch with QP especially with those who interviewed you sending the message that you are waiting..wishing you goodluck.
