Review the actual reassignment and each family member’s current status and document dates. A corporate change should not be treated as automatically extending the household’s permission.
Check the family implications of the real change
For a spouse planning to work, confirm valid L dependent status and appropriate spouse-specific I-94 evidence. An unmarried child under 21 may remain eligible as an L dependant but does not receive that spouse work authorization; assess any approaching age or status limit separately.
L-2 spouses are employment-authorized incident to status, but they should hold the proper status and documentation before relying on that authorization. A transfer between related companies can generate a new petition receipt, and dependent paperwork should be checked against that updated filing rather than assumed to carry over automatically. Ask the employer's immigration counsel whether the move requires an amended or extension filing, since a dependent's status is generally tied to the same underlying approval as the principal's. Store each family member's admission record, receipt notice and passport separately so mismatched dates surface before they become a problem, rather than relying on memory or a shared folder. Hold off on school enrollment, lease renewal or banking decisions that assume continued status until the updated paperwork is confirmed, since those commitments outlast whatever approval notice initially supported them. Treat a move between related entities as its own event worth its own paper trail, separate from whatever supported the earlier transfer.
