The job title alone does not decide dependent permission. A qualifying L spouse may work incident to valid dependent status with appropriate evidence, including the applicable spouse-specific I-94 classification.
Review status when the principal’s assignment changes
Do not assume the principal’s new approval automatically updates every family member’s documents. Qualifying unmarried children under 21 may hold L dependent status but do not receive the employment authorization available to qualifying spouses.
Testing work needs assessment under the spouse’s actual immigration permission. Confirm individual status and any separate occupational requirements for the intended job. An assignment of this length sits at the point where families are divided on whether to move. The company’s need to complete a migration does not authorize a dependent’s participation by itself. Determine exactly what the spouse would do, where the services occur, who directs them, and whether compensation or business benefit is involved. The principal’s L-1B time is limited to five years, so travel and extension records should be retained. The accompanying spouse is separately employment-authorized incident to status, which is often the more useful fact for the household budget.
