Vhiangzlkdlfw first of all I believe there is a possibility that IF the husband and wife are under different sponsors and if the wife has been working for over a year with the other sponsor, it is possible to transfer her sponsorship under husband if her company will give her an NOC to do so...under such a case the salary bracket is not an issue and you can be transferred under his sponsorship without any problems. Regarding your baby as others have mentioned your child will also be under husband's sponsorship regardless of salary or designation.
