# United States of America (federal jurisdiction)

A principal declaring `subject_to: ["US"]` states that they are subject to the federal law of the United States of America — typically by residence, incorporation, citizenship, or substantial operation there.

ISO 3166-1 alpha-2 code: `US`. State-level jurisdiction is declared separately with ISO 3166-2 subdivision codes (for example `US-CA`), which compose with rather than replace this one.

Jurisdiction declarations are good-faith disclosure, not warranty, and nothing in this entry is legal advice (IFP-21, Section 4).
