You, as the sponsor of your family member, can submit the application and copies of the supporting documents to the IND by post (if your family member does not yet possess a residence permit) or online using your DigiD (if your family member wants to change their permit to a family permit). Your employer (if they are a recognized sponsor of the IND) can also submit the application online for your family members.
There are specific conditions that the family member must fulfill. You can read more about the process, conditions, and exceptions for Non-EU family members at this page and for Non-EU family members of EU citizens at this page on the IND website.
Please be aware that the IND has a legal decision time after receipt of the application of 90 days.
