its not that easy to changes your designation more often happen is you need to resign and rehired again in your company with different item again it defends which comm you are right now.....dont trust those people who promise you that they can help you trust me charges to my own experience.they suck everything you got for nothing dont be a fool cause they know you need it badly....what can i advices is send your wife were ever she came from then as soon the plane leaves in qatar go to emigration and apply again in a week time she can come back or if you have time find a company that can sponsor her or let her work and everything will be ok hope help you God bless
