A qualifying L spouse’s employment authorization arises from status with appropriate documentation, not from matching the principal applicant’s professional background.
Review the intended job and actual status
Confirm individual status and any separate requirements for the intended occupation. Children receive no work permission solely through L dependent status. The applicant’s logistics evidence does not establish another person’s immigration rights.
The former customer’s invitation, the principal’s L-1B approval, and an unsigned offer do not independently authorize the spouse. The principal’s L-1B case separately needs one continuous qualifying year abroad in the relevant three-year window, a qualifying related organization, and company-specific specialized knowledge required by the US assignment. Unmarried children under twenty-one accompany the family and may attend school, but nothing in the derivative status permits them to be employed. Children under 21 hold L-2 derivative status, may enrol in school and have no work authorization; a child reaching 21 during the assignment needs an independent basis to stay, which should be planned before departure rather than after the birthday. None of this depends on the principal's plant or on the length of the assignment; it depends on each person's own valid L-2 admission and passport validity.
