The first question in any E-2 consultation is always the same: what passport do you hold? Treaty nationality is the threshold requirement for the E-2 program. If your country does not have a qualifying treaty with the United States, no investment amount, no business plan, and no attorney can make you eligible.

More than 80 countries currently have qualifying treaties with the United States. The list is broad and includes most of Western Europe, much of Latin America, significant parts of Asia and the Middle East, and several African nations. But it also has some notable gaps, including several of the world's largest economies.

Notable Non-Treaty Countries

Some of the world's largest economies are not E-2 treaty countries, which affects a significant number of aspiring investors. The major non-treaty countries include:

Citizens of these countries cannot use the E-2 program regardless of how much they wish to invest. Alternative investor pathways, such as the EB-5 immigrant investor program, may be available depending on the situation. See the comparison in E-2 Visa vs. EB-5: Which Investor Visa Is Right for You.

What If You Hold Dual Citizenship?

This is one of the most practically important questions in E-2 planning. If you hold citizenship in two countries, and one of those countries is a treaty country while the other is not, you may be able to use the treaty country nationality to apply for an E-2 visa.

For example, a person who holds both Indian citizenship and Irish citizenship could potentially apply for an E-2 through their Irish passport. Ireland has a qualifying treaty with the United States, and Irish nationality would be the basis for the application.

The key practical consideration is where you apply. You would typically apply at the U.S. consulate in Ireland, and you would enter the United States on your Irish passport. The application is based on the treaty nationality, not the non-treaty one.

Some people pursue citizenship in a treaty country specifically to unlock E-2 eligibility. Several countries offer citizenship by investment programs that, once complete, would allow the investor to then pursue an E-2 visa for U.S. entry. This is a longer and more complex path, but it is a real option for nationals of large non-treaty countries who are serious about U.S. business investment.

How the Treaty Requirement Actually Works

The treaty requirement is rooted in international agreements that predate modern immigration law in many cases. These are bilateral treaties of commerce and navigation, or friendship, commerce, and navigation treaties (FCN treaties), plus more recent bilateral investment treaties (BITs). When the U.S. entered into these agreements, they created reciprocal rights for nationals of each country to conduct trade and business activities.

The E-2 visa category was created to implement these treaty rights in the immigration context. That is why the program is limited to treaty country nationals. It is not a domestic policy choice in the usual sense. It reflects international commitments.

Interestingly, not all treaties are identical. Some countries have more favorable treaty terms than others, though in practice, the differences rarely affect individual applications. What matters is whether the treaty exists.

What Happens at the Consulate

When you apply for an E-2 visa, you typically apply at the U.S. consulate in your treaty country. If you are a Canadian citizen, you would usually apply at a U.S. consulate in Canada. If you are a British citizen, typically in London or Belfast.

The nationality requirement means you need to present the correct passport at your interview. If you are using dual citizenship to qualify, make sure your attorney has structured the application around the treaty nationality from the beginning, including which passport is primary and which consulate you are applying at.

Preparing your full application correctly from the start is critical. Understand all E-2 visa requirements and how they interact with your specific situation before you commit significant funds.

Treaty Countries Can Change

The list of treaty countries is not static. Countries can be added or removed, though changes are relatively rare. The U.S. Department of State maintains the official and current list of qualifying treaty countries and should be your authoritative source for verification.

If you are planning an investment partly based on treaty eligibility, confirm your country's status with a qualified attorney before committing funds. This is especially relevant if you hold the passport of a country that has had shifting diplomatic relations with the United States.

Key takeaway: Treaty nationality is the first and most absolute E-2 requirement. Over 80 countries qualify, but some major economies do not, including China, India, Brazil, and Russia. If you hold dual citizenship and one nationality is a treaty country, you may be able to apply through that passport. Always verify your country's current treaty status before making investment decisions.
