The spouse’s permission depends on qualifying valid L status and appropriate evidence, not the principal’s technical specialty.
Verify the individual authorization
Check the spouse’s actual status and relevant I-94 evidence before relying on employment authorization. The principal’s approval alone does not grant it. Dependent unmarried children under 21 do not receive the spouse’s work permission.
A child admitted in L-2 may attend school full time, but that status carries no work authorisation, so paying them for translation would be employment they cannot lawfully accept, and the fact that the work supports a parent's petition changes nothing. Classify each proposed administrative task before the spouse performs it: enrolment messages, scheduling, attendance tracking, technical support, and payment handling may all be productive work even if brief, remote, or unpaid. If the spouse's employment is intended to continue beyond the assignment, an employer-sponsored route in the spouse's own right takes time to arrange and cannot sensibly be started in the final months. If the family intends to stay for the whole assignment, list each person's passport and Canadian status, since a spouse or child who is a permanent resident rather than a citizen will process L-2 at a consulate rather than at the border.
