A project credit does not authorize another person’s work. Review the spouse’s actual status and intended activity separately.
Confirm the appropriate individual documentation
Qualifying L spouses are employment authorized incident to status with appropriate documentation. Children receive no work permission solely through L dependent status. A shared creative project or family relationship does not itself establish employment authorization.
Work permission is proved by a document held in the spouse’s own name, and no project record substitutes for it. After entry, retrieve the spouse’s admission record from the official system and check the class it shows; a qualifying L spouse is employment authorized incident to status with the appropriate documentation, which an employer will normally want to see rather than hear described. Children hold no such permission through dependent status, whatever the family’s involvement in the same work.
Keep the civil documents establishing each relationship — marriage certificate, birth certificates naming the parents — with certified translations where the original is in another language, because those are the records asked for when a status question arises later. Hypothetical example: two people work in the same quality function and assume that a joint contribution to one procedure will let both be engaged at the U.S. site; the procedure is silent on immigration, and each person’s own record decides the point.
