[Circular—No. 18.]
To the diplomatic and consular officers of the United States in foreign countries.
Department of State,
Washington,
August 8, 1862.
It is expected that, until further notice, you will not issue a passport to any citizen between the ages of eighteen and forty-five, and otherwise liable to the performance of military duty, who you may have reason to suppose shall have left the United States subsequently to this date.
