NO.. your employer must cancel first your RP and you need to return to your home country...You must acquire also NOC to comeback to qatar. Even you will be sponsored by your husband, the immigration will ask your noc when applying your visa to the immigration dept.
there are many rules now here in qatar..
try to follow up to your employer the transfer of your sponsorship to family visa..i have a friend who is recently applied the transfer of her visa to husband,before many times it was rejected and the PRO tried to resubmit until it was approved..
