Each family is separate. Different partners have different employment needs, different children fall on different sides of the under-twenty-one dependent limit, and school timing varies. Group relocation support can be arranged jointly, but immigration eligibility for each spouse and child is assessed on that family's own facts.
Ask each household what it actually needs
Some partners will want employment authorization and others will not; a spouse in valid L-2S status is employment-authorized incident to that status, and children in dependent status are not work-authorized. Where a child is close to the age limit, raise it early with counsel. Avoid a single relocation package that assumes every family has the same shape, since that is how one household's needs go unnoticed until the move is underway.
