The spouse’s work needs its own valid status basis. A qualifying L spouse may work incident to status with appropriate evidence, but the principal’s need for help does not create permission.
Do not use an assumed family role as staffing evidence
Describe genuine staffing and separately assess the spouse’s intended work. Eligible L dependents include a spouse and unmarried children under 21; children receive no spousal work benefit. A hypothetical family contribution should not be presented as an existing employee.
Confirm the spouse's current status documentation rather than assuming a document is automatically issued, and keep a child's study plans and any age-related questions under separate review from the spouse's work authorization. The principal’s L-1A case still depends on a qualifying corporate relationship, the required continuous foreign-employment year, and managerial or executive American duties; share ownership does not alter the derivative test.
Where an assignment is expected to run toward the outer limit, generally seven years for L-1A, the household is planning around a temporary status, and decisions such as buying property or a spouse leaving a Canadian position deserve their own advice.
