YOUR COMPANY ARE NOT ALLOWED TO SPONSOR YOUR CHILD BECAUSE YOUR CHILD IS YOUR IMMEDIATE FAMILY AND ONLY THE PARENTS CAN SPONSOR HIM/HER. THE BEST THING YOU CAN DO IS TO SPONSOR YOUR CHILD VIA FAMILY VISIT VISA THEN ONCE HE/SHE IS ALREADY HERE, YOU HAVE TO APPLY FOR A FAMILY RESIDENCE VISA. ALL YOU HAVE TO DO IS TO PROVIDE YOUR SALARY CERTIFICATE TOGETHER WITH YOUR HUSBAND SALARY CERTIFICATE. THERE IS NO GUARANTEE THAT THEY WILL APPROVE IT BUT THAT IS THE ONLY WAY YOU CAN DO AND HOPEFULLY, THEY WILL APPROVE IT. GOD'S PERMIT....
