get also opinion from other people who have experienced the same situation like yours... only one thing is for sure, you can never transfer or change your current visa without cancelling it first... i also suggest you try to discuss it with your company... perhaps they will allow you... some companies prefer to hire staff under husband sponsorship... if they allow you, there is no need for you to exit qatar... ask also the immigration about the procedure on how to change sponsorship while you are still here in qatar after cancelling your current visa... i just hope your company allows you to change your sponsorship... otherwise resignation is your last option... good luck...
