Platform familiarity does not establish immigration work permission. Assess the spouse’s own status and authorization.
Separate skills from permission
Qualifying L spouses may work incident to appropriate status with evidence, but the principal’s expertise or pending transfer does not authorize the spouse’s job.
Record citizenship, relationship evidence, and ages, and verify the spouse's own documentation rather than assuming the L-1B label changes anything about dependent permissions. Immigration derivative status turns on a legal marriage recognised where it took place, and a common-law or domestic partnership does not qualify, however long standing and however documented. The harder planning question is what the family does when the maximum is reached, because L-1B allows five years rather than the seven available in L-1A, and derivative status ends when the principal’s does. 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. Dependent child status ends at twenty-one, so a household relying on a teenager's help across a multi-year assignment should count those years before the transfer begins rather than after it.
