A system-migration contract cannot give the specialist’s spouse permission to work. The qualifying spouse’s employment benefit comes from valid L status with appropriate documentation; dependent children do not receive that benefit.
Separate the project access list from the status check
A migration plan may list people for training, testing or after-hours support. If it includes the spouse, identify the actual tasks and work location before allowing the list to become a start instruction. Client approval, a badge and access to a test environment establish no immigration status. L dependent eligibility concerns a qualifying spouse or unmarried child under 21. Check the spouse’s own admission evidence and dates rather than attaching the principal’s project paperwork as a substitute.
Families sometimes plan a move on the principal's role alone and then find the spouse's position is either much better or much worse than assumed depending on the classification chosen. The principal’s L-1B classification still rests on the qualifying relationship, continuous full-time foreign year within the prescribed three-year period, and specialized-knowledge duties.
