Transfer of sponsorship of a local hire depends on a number of factors, among those are the position and salry of the job specially if this is with givernment or a company subject to Qatarization

You may have done a CID clearance or not depending on the case ... and this is the stage I am asking for

Have you got your CID clearance certificate ...

If this is the one that is rejected then you should look for some other company

Check with your management what is the nature of the problem and if they think it will not be agreed let them give you a deadline in your case this deadline has to be before your residence expires, otherwise you will be in trouble ... let them know that you will be free to look for other employment if they can not get your approval by the date they tell you ... try to be clear on this with no hard feelings

Good luck
