That is a business decision and a separate status question. A qualifying L spouse can work incident to valid status with appropriate evidence; anticipated eligibility does not authorize work before that status exists. The appropriate spouse-specific I-94 classification can provide evidence of that status.
Document the real staffing arrangement
Do not count a planned family hire as present support. Children who qualify as unmarried L dependants under 21 do not obtain the employment authorization available to qualifying spouses.
The principal’s approval does not automatically put the spouse in status. The spouse may therefore take a paid role with the subsidiary, with a different employer or in self-employment. Attending as a family member does not itself authorize productive client work. An L-2 child does not receive the spouse’s employment permission. Confirm admission records and document classification before completing onboarding or providing services. A spouse in L-2 status is employment-authorized incident to status, which is a genuine difference from other categories and is often the practical reason a family chooses this route. Review the spouse’s actual procedure and any independent authorization before a work start. A commercial driving licence valid in the state is a separate matter.
