your situation is not clear? you say your husband cant get the necessary resident family visa, but how are you staying until March? you are already on a family visit visa, why cant he get the visa for your daughter and you? be clear about this issue. Secondly, if you want to sponsor your child you need to find a job with salary of QR10000..but for that you may face difficulties as not only it takes time, a lot of visas get rejected if wife apply, and not husband. What is reason he cant sponsor you and the baby?
