An official passport is a passport which is issued to someone who must travel internationally on official state business. These passports are issued specifically to people who need to travel, rather than to people who are being assigned or posted overseas.
Official passports are issued only in Washington, DC, at the Special Issuance Agency of the Washington Passport Agency. US citizens may hold both a valid official passport and a valid personal passport at the same time. Official passports are only to be used when traveling on government business, so any leisure travel must be done with a personal passport.
