Summary

It is a crime for anyone in the United States to join, or hire someone to join, a foreign army, navy, or crew of a warship or privateer, or to go abroad to do so. A person who does this can be fined under federal law, jailed for up to three years, or both. People who are citizens of a foreign country that is at war with a country the U.S. is also at war with are not covered by this rule, unless they recruit U.S. citizens; those enlistments must follow rules set by the Secretary of the Army. Also, foreign visitors passing through the U.S. may join a foreign warship that was already armed and equipped on arrival, or hire another such visitor to join, if the U.S. is at peace with that country.

Historical and Revision Notes

Based on title 18, U.S.C., 1940 ed., §§ 22, 30 (Mar. 4, 1909, ch. 321, §§ 10, 18, 35 Stat. 1089, 1091; May 7, 1917, ch. 11, 40 Stat. 39). Section consolidates said sections of title 18, U.S.C., 1940 ed. Last sentence of section 30 of title 18, U.S.C., 1940 ed., relating to piracy and treason, was omitted as unnecessary. Words “within the United States” were substituted for “within the jurisdiction” etc., in view of the definition of United States in section 5 of this title. References in subsection (c) to section 960 and 961 of this title are to the only other sections to which the subsection can apply. Mandatory punishment provision was rephrased in the alternative. Minor changes were made in phraseology.

Editorial Notes

Amendments
