The spouse’s permission depends on the actual immigration status and required evidence, not the principal’s internal title.
Check the actual family status record
Qualifying L spouses may work incident to appropriate status with required evidence; children do not receive those spouse rights. Do not use an employer’s reclassification letter as a substitute for the spouse’s own work-authorizing basis.
A change in the principal’s internal title does not grant, remove, or extend the spouse’s work authority. Confirm the spouse was admitted in valid L-2 spouse status and retain the appropriate status evidence; employment authorization is incident to that status. L-2 children do not share the spouse employment benefit. Compare expiration dates for each family member, and examine any gap caused by travel, extension filings, or a change of classification before accepting work. Separately, the principal’s L-1B case must show the qualifying related organizations, one continuous year of foreign employment during the relevant three years, and special or advanced company knowledge used in the US role. A new title cannot substitute for those facts, and L-1B time generally ends at five years. The recurring mistake is sending an employer promotion notice to payroll as though it were the spouse’s immigration document.
Hypothetical example: An aquaculture-software implementation specialist from Sainte-Rose-du-Nord is promoted before transfer. His spouse plans to provide bookkeeping services after arriving in the United States. She relies on her correctly documented L-2 spouse admission, not the promotion letter; their child remains ineligible for employment through L-2 status.
