A legally married spouse admitted in qualifying E dependent status is generally employment-authorized incident to that status, which can include working in the enterprise. Confirm the actual proof: the E-2S annotation or the I-94 class of admission, or other applicable evidence. Unmarried children under 21 may accompany but gain no work authorization from dependent status.
Do not build the roster on assumptions
If the operating plan depends on a spouse supervising leased machinery, say so before filing, because the household's work would then rest on that person obtaining and maintaining applicable work authorization. Family members go through their own process, and their appointments and approvals are not guaranteed to arrive with the principal's. Neither living in the United States nor being paid by the company creates authorization on its own. Plan a staffing fallback if the spouse arrives later.
List each family member's citizenship, relationship evidence, age and intended work or study plan. The principal applicant must genuinely develop and direct the enterprise, and that role is performed in lawful E-2 status. If the spouse expects to operate a different business, identify that plan explicitly rather than quietly adding its projected earnings to the investor company’s forecast. Children may attend school but cannot work, and they lose E-2 dependant status at 21.
