HMC visa cancelled what to do ?

Dear Friends,
After lot of interviews, documentation, and communiq for last 1 year finally I got an offer from HMC Qatar. The job offered is departmental head position and I am an MBA from an Indian University. I left my present job in India since my visa has been applied by HMC 3 months back. But to day HMC is saying that my visa application has been cancelled by the ministry and no reason has been confirmed.

As a family man what situation I am in now no one can imagine. Can you tell me whether I can request HMC to re-apply for visa once again. Or else can I myself directly follow up with the visa authorities from India any way. If you suggest the second way then how ? Under this pathetic situation I would really be grateful to all who tries to guide me.

Did Hmc tell you, Leave the current job?
Hmc will not push until the single entry visa is issued from the ministry.

Resigned before you got Visa....  :unsure  Are you serious??!!!
