Read the general investor planning overview
Different citizenships in one household change which category each person can use, and dependent status does not carry citizenship-based eligibility on its own. Map each person's route separately before assuming the household moves together on one filing.
Check the principal applicant's own eligibility first
A route like E-2 requires the principal applicant to hold the nationality of a qualifying treaty country and to control a qualifying at-risk investment; a spouse's citizenship does not substitute for this. If the intended principal applicant does not hold that nationality, look at whether another category fits their own facts before assuming the investment plan can proceed as an E-2 filing.
Confirm dependent status separately from citizenship
A qualifying E-2 spouse is employment authorized incident to valid E-2 spousal status; the spouse's own treaty nationality is not what grants that authorization. A separate EAD application is optional. Verify the spouse's I-94 and acceptable employment evidence, and assess dependent children separately because their E-2 classification does not authorize work. The special E-2 CNMI investor rules differ from this ordinary treaty-investor framework.
Document the sequence, not just the outcome
Record which family member's status depends on which underlying filing, and what happens to each dependent if the principal applicant's case changes. A household plan built around one assumed category can leave the wrong person without a route if the citizenship facts were not checked person by person from the start.
Decide who the principal investor will be before any account is opened
In a household where the members hold different citizenships, the identity of the principal investor is a decision rather than a default, and it is far cheaper to take before money moves than afterwards. Two nationality tests operate here. The individual seeking the classification must hold the treaty country's nationality. Separately, the enterprise itself must possess that nationality, which generally turns on ownership by nationals of the treaty country, so the ownership structure has to be arranged with the requirement in view rather than corrected against it later. A couple who open accounts, incorporate, and transfer funds in the name of whichever spouse was available that week can find the structure works against the only person able to use it. Note too that an employee of a treaty enterprise generally needs to share the enterprise's treaty nationality, so a spouse hoping to take a senior role in the business is not automatically placed by the family relationship alone. Hypothetical example: a couple buying a boat repair yard assume the spouse with the business background should hold the shares, then find that the other spouse holds the qualifying nationality, and restructure at the term-sheet stage rather than after completion, which costs a redraft rather than a second set of transfers and a fresh explanation of where the money went.
