It does not replace the principal’s own employment evidence.
Review each person’s records for their purpose
Family travel may provide context without proving duties or service. A qualifying L spouse’s work permission also depends on actual status and required evidence, not the principal’s travel reconstruction alone.
Spouses of L-1 principals hold L-2 status and are considered employment-authorized incident to that status, so no separate employment document is needed once the admission record carries the L-2S annotation. Each dependent needs a passport valid for the intended period, evidence of the relationship such as a marriage certificate or a long-form birth certificate, and any change-of-name document that reconciles the records. Keep children's schooling plans separate from questions about work authorization or aging out of dependent status, since the principal applicant's proposed start date does not automatically resolve those questions. A larger role does not widen a dependant's permissions, and a household that plans around the promotion rather than around each person's status tends to discover the gap only after arrival. Where a spouse expects to work, discuss their position specifically rather than assuming it follows from the principal's case, and avoid long leases or resignations agreed before the structure is settled.
