The spouse needs appropriate E spousal status and evidence before relying on incident-to-status work authorization. The purchase itself provides no such permission.
Check the person and the proposed activity
Describe the spouse’s intended work separately from ownership or asset title. An EAD is not universally necessary for a qualifying E spouse, but the actual records matter. Eligible unmarried dependent children under 21 do not receive that spouse permission, including in the family business. Confirm each person’s status before assigning operational tasks.
Nothing about the process guarantees a decision by a given date, and the spouse's ability to work in the United States depends on the principal being approved, admitted and in valid status first. Children under twenty-one may live and study but never work, and because E-2 offers no direct path to permanent residence, a child who reaches twenty-one loses derivative status entirely. The shared limitation is the one that shapes long-term planning: E-2 is a nonimmigrant category tied to the enterprise, renewable while the business continues to qualify, but it does not itself lead to permanent residence. A legally married spouse who holds valid E status is generally employment-authorized, but that is a separate process and not a guaranteed second income by a fixed date.
