JPMorgan Chase Bank v. Traffic Stream (BVI) Infrastructure Ltd., 536 U.S. 88 (2002), was a case in which the Supreme Court of the United States held that a corporation organized under the laws of a British overseas territory is considered a "citizen or subject of a foreign state" for purposes of federal court jurisdiction.

Traffic Stream petitioned the U.S. Supreme Court for certiorari, with the support of an amicus curiae brief from the government of the United Kingdom.

Justice David H. Souter wrote the opinion for a unanimous Court, reversing the Second Circuit's decision and holding that a British Virgin Islands company like Traffic Stream was properly considered a "citizen or subject of a foreign state" for jurisdictional purposes.

The Supreme Court disagreed, finding the distinction drawn by the Second Circuit to be "entirely beside the point of the statute providing alienage jurisdiction."

The fact that British Virgin Islands residents are not citizens or subjects of the United Kingdom under British nationality law, the Court held, did not negate that they are citizens or subjects of a foreign state for purposes of the alienage jurisdiction statute.
