The United States marks 250 years since the Declaration of Independence on July 4, 2026, but one of the most practical legal links between the United States and the United Kingdom is older than modern immigration law: the 1815 commerce treaty that still supports E-1 treaty trader and E-2 treaty investor visas for British nationals.
The Convention to Regulate Commerce and Navigation between the United States and His Britannic Majesty, 8 Stat. 228, was signed in London on July 3, 1815. It was concluded on behalf of the Prince Regent, later King George IV, and remains the legal basis for British access to the U.S. E-1 and E-2 categories.
The timing is notable. The War of 1812 ended with the Treaty of Ghent, signed on December 24, 1814, with ratifications exchanged in February 1815. Less than five months later, the two governments signed the commerce convention on July 3, 1815. Article IV of the Convention of 1818 confirmed it for another ten years, and a 1827 convention extended it indefinitely.
The treaty has never been abrogated.
Why the 1815 treaty still matters
Modern U.S. immigration law relies on the existence of a qualifying treaty for treaty trader and treaty investor classification. Section 101(a)(15)(E) of the Immigration and Nationality Act conditions E-1 and E-2 eligibility on a treaty of commerce and navigation between the United States and the applicant’s country of nationality.
The State Department’s treaty country list at 9 FAM 402.9-10 records the United Kingdom’s effective date as July 3, 1815, making it the oldest entry on the list.
In practical terms, British investors can still apply through the U.S. Embassy in London under a treaty signed more than two centuries ago.
The geographic limitation for British applicants
The 1815 Convention does not apply automatically to every British passport holder. Under the State Department interpretation at 9 FAM 402.9, the treaty applies only to British territory in Europe:
- the British Isles, except the Republic of Ireland
- the Channel Islands
- Gibraltar
It also applies only to “inhabitants” of that territory.
An “inhabitant” is described as someone who actually and permanently resides in a place and has domicile there. This creates an important restriction: a British passport alone is not enough.
A British citizen who has lived for years in Dubai, Singapore, or another non-qualifying place may not qualify until residence in the United Kingdom or another qualifying territory is genuinely re-established.
Applicants in London may be asked to document residence through evidence such as:
- tenancy agreements
- council tax records
- payroll documents
- utility bills
Commonwealth nationality also does not qualify by itself. Nationals of Commonwealth countries other than the United Kingdom do not qualify for E-1 or E-2 status under this treaty.
Shared legal roots, different constitutional systems
The United States and United Kingdom share common law foundations. Both systems draw on legal concepts including binding precedent, adversarial procedure, trial by jury, habeas corpus, and due process ideas traceable to the Magna Carta of 1215.
The constitutional structures are different.
The United States has a written constitution and, since Marbury v. Madison, 5 U.S. 137 (1803), judicial review allowing courts to strike down legislation.
The United Kingdom has an uncodified constitution and parliamentary sovereignty. Courts cannot invalidate an Act of Parliament.
For immigration practice, this affects how government decisions are challenged. In the United States, challenges to agency action proceed under the Administrative Procedure Act, including the arbitrary-and-capricious standard. In the United Kingdom, the equivalent route is judicial review in the Administrative Court, described as narrower, faster, and subject to strict time limits.
Immigration systems have diverged sharply
Despite shared legal roots, U.S. and UK immigration law now operate very differently.
Citizenship is one major divide. The United States grants citizenship by birth on U.S. soil under the Fourteenth Amendment, ratified in 1868. The United Kingdom ended automatic birthright citizenship when the British Nationality Act 1981 came into force on January 1, 1983. A child born in the UK today is British at birth only if a parent is a British citizen or settled in the UK.
The selection systems also differ. The United States uses family and employment preference categories, annual numerical limits, per-country caps, and a diversity lottery. This structure comes from the Immigration and Nationality Act of 1952, as amended in 1965 and 1990, and can produce backlogs lasting years or decades for some nationalities.
The United Kingdom uses a sponsorship-based points system with no per-country caps and no diversity lottery.
Investment migration: one-way treaty benefits
Investment migration is where the two systems separate most clearly.
The United Kingdom closed its Tier 1 (Investor) route in February 2022.
The United States still has:
- the E-2 nonimmigrant investor route
- the EB-5 immigrant investor program
- the Trump Gold Card, introduced by Executive Order 14351 on September 19, 2025
The Trump Gold Card has been open for applications since December 18, 2025. It is described as offering permanent residence through existing EB-1 and EB-2 categories in exchange for a $1 million gift to the federal government, with a $2 million corporate sponsorship version. The article notes that it was created by executive order, not an act of Congress, and that this distinction is being tested in federal court.
There is no reciprocal UK treaty route for American investors. An American entrepreneur seeking to establish a business in Britain must qualify under the UK’s domestic business immigration rules.
In practice, the 1815 Convention benefits British investors seeking entry to the United States, but not American investors seeking an equivalent treaty route into the United Kingdom.
The political relationship is less stable than the treaty
The phrase “special relationship” entered common usage with Winston Churchill’s speech in Fulton, Missouri, in March 1946. By that measure, the branded partnership is around 80 years old in 2026, far younger than the 1815 commerce treaty.
The broader relationship has recently become more strained. A 2026 Gallup survey recorded American favorability toward the United Kingdom at 76%, described as the lowest figure on record and down from 84% in 2025. Among Republicans, favorability reportedly fell from 84% to 64% in one year.
The article also cites March 2026 remarks by the U.S. President after London declined to endorse strikes on Iran, saying Britain’s current leadership was no Winston Churchill.
Polling by The Economist and YouGov ahead of the semiquincentennial found that fewer than half of Americans described themselves as very proud of their nationality, while roughly two-thirds believed the country’s best years were behind it.
The United Kingdom has also signaled a shift in orientation. At a Downing Street press conference on April 1, 2026, Prime Minister Keir Starmer said Britain’s long-term national interest requires “closer partnership with our allies in Europe and with the European Union.” The article frames this as a possible reorientation away from Washington.
For investors and transatlantic families, such shifts can affect decisions about where to live, base businesses, structure assets, and maintain residence rights.
The practical point is that political moods can shift, but the 1815 Convention remains legally operative. As the United States reaches its 250th anniversary, British investors can still rely on a treaty signed in London on July 3, 1815, to seek E-1 or E-2 access to the United States.
