A staffing plan and the enterprise’s operating requirements need their own evidence. A qualifying E spouse may have work authorization incident to valid status, but that does not establish business capacity.
Avoid an unsupported operational assumption
Describe real contributions without treating a relative’s possible work as a universal solution. The dependent category is for a qualifying spouse or unmarried child under 21; each person needs valid status.
The principal's case must show treaty nationality, irrevocably committed funds exposed to loss, substantiality, a genuine non-marginal enterprise, and development and direction through 50% ownership or operational control. Children stop qualifying as derivatives at twenty-one, and a treaty investment can run for many years, so a family with a teenager should assume that a separate status will eventually be needed and plan the timing rather than react to it. Explain any intended operating work separately from passive ownership and review the actual activity rather than assuming a family property arrangement authorizes everyone to run the business. Discuss any independent employment plans and the children's future status questions explicitly, rather than assuming a shared business plan settles the whole household's arrangements.
