Regarding Exit ReEntry.

Hello all
I am in a delima as I had applied for a Exif ReEntry and as I recieved it the Passport number is of the Old passport which was damaged Hence I had made a new one.
But now I see the new one is not updated with MOI and it's still registered on the old one.
Will this be an issue? Please help.

Could be a problem.  Go first to Jawazat to get the new passport number updated in their system.  Then ask your sponsor to cancel the exit re-entry and issue a new one.
