The principal’s letter does not establish the spouse’s status. A qualifying L spouse may work incident to valid status with appropriate evidence.
Assess the actual person undertaking the task
Eligible temporary dependents include a spouse and unmarried children under 21, and children receive no spousal work benefit. A separate company task still needs a lawful basis for the family member’s activity.
Identity and status evidence sufficient for employment eligibility verification, including the admission record showing the relevant classification, together with the marriage documentation used for the dependant application. L-1B requires qualifying organizations doing business, twelve continuous months of qualifying employment abroad during the relevant preceding thirty-six months, and specialized knowledge for the U.S. assignment. Children may generally study under the published guidance and hold no work permission through dependent status, and one who reaches twenty-one during the placement stops fitting the derivative classification entirely. If a child turns twenty-one during the assignment, derivative status ends on that birthday whatever the parent's remaining period, and a student route with its own admission and financial requirements takes time to arrange. A dependant's authorized period is derived from the principal's and can be granted shorter than the household expects, while school registration, a lease and a spouse's employment authorization each answer to a different calendar and a different office.
