L dependent child status does not authorize employment, even if the work is temporary or within the parent’s company.
Separate the child’s activity from the transfer
Record age, marital status, study plans and the proposed tasks. Eligible unmarried children under 21 may qualify as L dependents, but that does not give them the qualifying spouse’s work benefit. Any internship or paid activity needs assessment under the child’s own circumstances and authorization.
Practical enrolment questions are usually resolved by the school district, which asks for proof of residence, immunization records and previous transcripts rather than immigration documents beyond status. The usual alternative for a student is a course of study with a school authorized to enrol foreign students, and that route has its own admission timetable, financial documentation and issuance steps. The practical consequence of the FAM position is that dependent periods must be provable rather than merely asserted: keep the dependent approval or the record of admission showing the classification, not simply a recollection that the family travelled together. Where a family previously moved together, the questions worth re-asking are narrow: has any child married or turned 21, does any family member now hold a different status, and has any document been superseded by later travel.
