E-2 Visa and Dual Nationality: Which Treaty Country to Use

To qualify for E-2 classification, the investor must be a national of a treaty country. 8 CFR 214.2(e)(1) defines the E-2 nonimmigrant as an alien who is a national of a country with which the United States has in force a treaty of commerce and navigation, or a bilateral investment treaty, or in which Congress by legislation has made applicable the provisions of the classification. The definition turns on nationality, not domicile, tax residency, or the investor's country of business incorporation.

Under 9 FAM 402.9-4(A), nationality is determined by the law of the investor's claimed treaty country. A person holds the nationality of a country if that country treats the person as its citizen or subject. The FAM does not restrict applicants to a single nationality when they hold more than one: what matters is that one of the nationalities corresponds to a qualifying treaty country.

The practical consequence is straightforward: a dual national who holds the citizenship of at least one treaty country may apply for E-2 classification using that treaty country's nationality as the qualifying basis, even if the other nationality corresponds to a non-treaty country. The investor is not disqualified by also holding a non-treaty nationality, provided the treaty-country nationality is genuine and provable.

A valid passport issued by the treaty country is the standard proof of nationality for E-2 purposes. When a dual national applies for an E-2 visa at a U.S. consulate, the application is filed through the consulate of the treaty country: the applicant presents the treaty-country passport as the travel document, and the visa, if issued, is stamped in that passport. The non-treaty passport is generally not the operative document for E-2 consular processing, though an officer may ask about other nationalities held.

The DS-160 nonimmigrant visa application asks for all current passports. Applicants should list both nationalities accurately. Failing to disclose a second citizenship when asked is a serious misrepresentation under INA 212(a)(6)(C) and can result in a permanent bar. There is no advantage to concealing a second nationality, and the disclosure does not disqualify the application.

At the port of entry, CBP officers inspect the passport presented. An E-2 traveler entering on a treaty-country passport will be admitted in E-2 status tied to that passport. If the traveler also carries a passport from a country that has a U.S. entry program such as the Visa Waiver Program, traveling on the wrong passport for the wrong purpose creates status complications. E-2 holders should consistently enter the United States on the treaty-country passport that carries their E-2 visa stamp.

• Present the treaty-country passport for E-2 visa applications and U.S. entry
• Disclose all nationalities accurately on DS-160 — omitting a nationality when asked is a misrepresentation
• Always enter the United States on the passport that bears the E-2 visa stamp, not an alternative passport
• Keep treaty-country passports current — an expired passport creates complications at renewal and entry

Some investors hold dual citizenship in two different treaty countries — for example, a German-Australian citizen, or a Japanese-British national. In those cases, the investor can apply using either treaty country's nationality as the E-2 qualifying basis. The choice is not arbitrary: it carries practical consequences for where the application is filed, which consulate's procedures apply, and the visa validity period.

The consular post at which the application is filed is generally determined by the treaty country chosen as the qualifying basis. The investor may apply at any consulate of that country in the country where the applicant is a resident or domiciliary. If one of the treaty countries has a consulate in the investor's home country and the other does not, the first is the practical choice. Visa validity periods vary by consulate — reciprocity schedules set the maximum validity a U.S. consulate will issue to nationals of a given country. The U.S. Department of State reciprocity schedule at travel.state.gov lists the current validity and number of entries available for each country.

In most cases, the investor should choose the treaty country whose nationality provides the most favorable processing conditions — the most accessible consulate, the longest reciprocity period, and the most established E-2 adjudication track record at that post. Practitioners often review the denial rate data and processing times at competing consulates before advising on which nationality to use as the qualifying basis when both are available.

A common path for investors born in non-treaty countries is to naturalize in a treaty country before applying for E-2. Examples include investors from China, which is not a treaty country, who naturalize as citizens of New Zealand, Canada, or a European Union member state through marriage, descent, or long-term residence. Once naturalization is complete and the investor holds a valid passport from the treaty country, the E-2 nationality requirement is satisfied.

The timing of naturalization matters. The E-2 investment and the application for classification should follow naturalization, not precede it, because the treaty-country nationality must exist when the application is adjudicated. An investor who is in the process of naturalizing but has not yet received citizenship cannot use the anticipated nationality for an E-2 application. USCIS and consular officers adjudicate based on the investor's status at the time of their decision, not projected future nationality.

After naturalization, the investor should confirm that the treaty country recognizes them as a citizen — that the naturalization certificate or passport application has been processed and the investor can present a valid treaty-country passport. Some countries have waiting periods between citizenship grant and passport issuance; others process passports quickly. The E-2 application can be prepared and filed once the investor holds a valid treaty-country passport, and filing with the passport in hand is the cleanest approach.

A common misconception is that the U.S. enterprise itself must be a national of the treaty country. It is not. The E-2 enterprise must be owned at least 50% by nationals of the treaty country — meaning the investors who own and control it must hold the qualifying nationality. The enterprise itself is a U.S. entity, typically a limited liability company or corporation formed in a U.S. state.

Under 9 FAM 402.9-4(A)(2), an E-2 enterprise can be owned by a foreign entity rather than directly by an individual investor, provided the foreign entity itself is at least 50% owned by nationals of the treaty country. In that structure, the investor's nationality flows through the ownership chain. A French citizen who owns 100% of a French holding company, which in turn owns 100% of the U.S. operating entity, can qualify if France is a treaty country and the French company's ownership by French nationals is documented.

When a dual national investor owns the enterprise, only one nationality needs to provide the qualifying basis. The investor does not need to use both nationalities simultaneously. The ownership structure documentation — the operating agreement, the capitalization table, or the shareholder ledger — should reflect the investor's name and ownership percentage; the treaty-country nationality is then established through the visa application and passport documentation separately.

Dual nationals who are already inside the United States may be able to change status to E-2 by filing Form I-129 with USCIS rather than traveling abroad for a consular visa stamp. The change-of-status route requires that the investor be in a valid nonimmigrant status that permits a change to E-2. The same nationality requirement applies: the investor must demonstrate treaty-country nationality, and the I-129 petition must identify the treaty country.

For change-of-status applicants who entered on one nationality's visa and wish to apply for E-2 using a different treaty-country nationality, the analysis turns on what status the investor currently holds and whether that status permits the change. An investor who entered on a B-2 tourist visa using their non-treaty-country passport, but who also holds treaty-country citizenship, can file an I-129 to change status to E-2 using the treaty-country nationality. USCIS will evaluate the nationality claim and may request documentation of the treaty-country citizenship if not submitted with the petition.

One practical note: the E-2 status approved in a change-of-status proceeding does not include a visa stamp. When the investor eventually travels outside the United States and seeks to re-enter in E-2 status, they must obtain an E-2 visa stamp at a consulate of the treaty country. The passport presented for that consular appointment must be the treaty-country passport, consistent with the nationality used in the I-129.

E-2 status is tied to the qualifying nationality. When a dual national renews their E-2 — whether by filing an I-129 extension with USCIS or by traveling abroad and obtaining a fresh visa stamp at a consulate — the same treaty-country nationality must remain valid. If the investor's treaty-country passport has expired, it must be renewed before the E-2 renewal can proceed.

Dual nationals should be aware that renouncing or losing a treaty-country nationality after E-2 status is granted creates a problem at renewal. An investor who abandons their treaty-country citizenship — whether voluntarily or through the operation of another country's law — loses the qualifying nationality and cannot renew E-2 status. If the other nationality is also a treaty country, the investor may be able to pivot to that nationality for renewals, but this should be addressed with counsel before any citizenship action is taken.

The rule in 9 FAM 402.9-4(A) that nationality is determined by the law of the treaty country means that an investor should confirm their treaty-country citizenship status is active and unimpaired. Some treaty countries apply residence-based citizenship retention rules: nationals who live abroad for extended periods may face reduced passports or citizenship re-registration requirements. Investors who have lived in the United States for many years under E-2 status should confirm with the treaty country's consulate that their citizenship remains fully intact.

• Confirm treaty-country passport is valid and will not expire before the next E-2 renewal
• Do not renounce treaty-country citizenship while holding E-2 status without understanding the impact on future renewals
• Check whether the treaty country imposes residence-based rules that could affect citizenship status after years abroad
• If changing the qualifying nationality at renewal from one treaty country to a second treaty country, flag this for counsel — USCIS or the consulate may need additional documentation

The most frequent error is failing to disclose the second nationality on the DS-160 or in the I-129 cover letter. Officers routinely ask about other passports or citizenships during the E-2 interview. An applicant who has not disclosed a second nationality faces a misrepresentation issue that is far more damaging than the disclosure itself would have been.

A second common mistake is presenting the wrong passport at the port of entry. Dual nationals who use a non-treaty-country passport for convenience travel — for example, to avoid a long visa line — risk being admitted in a status inconsistent with their E-2. If the CBP officer admits the traveler in B-2 or VWP status because of the presented passport, the investor's E-2 record can fall into disorder. The entry record, Form I-94, should always reflect E-2 admission when the investor is traveling to maintain E-2 status.

A third mistake is assuming that dual nationality eliminates the at-risk and substantiality requirements. The nationality question is only one of several E-2 threshold tests under 9 FAM 402.9. Confirming treaty-country nationality satisfies the threshold eligibility question, but the investment must still be irrevocably committed, substantial, and deployed in a bona fide, non-marginal enterprise that the investor develops and directs.
