she needs a noc for the transfer of company to husband sponsorship but the company wont give noc. the best thing she can do is, file a resignation then she needs to exit qatar and she can come back under your sponsorship. you can submit an application for a family residence visa under your sponsorship. the only problem is, she is not allowed to work for 2 years under your sponsorship because of the work ban due to not having a NOC from her previous company.
