Each person must have an appropriate basis for the intended work. A shared management arrangement or marriage does not itself establish immigration authorization.
Distinguish business roles from status
Qualifying L spouses are employment authorized incident to status with appropriate documentation. Children gain no work permission solely through L dependent status. Identify the actual status each person will hold rather than assuming both qualify as principal managers.
The L-2 spouse may work for any employer without a separate authorization document, and children may attend school until 21. Where an employer is unfamiliar with the category and asks the spouse for documentation before a start date, it is worth confirming in advance what will be expected, because practice varies and a delayed start over a paperwork misunderstanding is avoidable. A spouse admitted in qualifying L-2 status is employment-authorized incident to that status, but the family should retain status evidence and confirm that the admission record identifies the spouse appropriately before duties begin. What that right does not do is satisfy a state licensing board, and families relocating around a spouse's regulated profession sometimes discover the sequencing problem only after arrival. Children have different work rules and generally cannot borrow the spouse’s employment right. Review the immigration implications for the principal and each family member using the actual transaction and current records.
