A diplomatic passport (black) is a type of no-fee passport used by a person having diplomatic status and traveling abroad for the discharge of duties. An official or employee of the government uses an official no-fee passport (maroon) for traveling abroad on state work. A no-fee regular passport (blue) is used by military dependents traveling at government expense. The bearer of a no-fee regular passport may use it for incidental travel while abroad if the government of that country does not object to it. Some governments have agreements with organizations like the Peace Corps; people going for overseas assignments on behalf of such organizations can use no-fee passports.
If a person is a widow, widower, child, parent, brother or sister of a deceased member of the U.S. Armed Forces who is buried or memorialized on Tablets of the Missing at an overseas military cemetery administered by the American Battle Monuments Commission, he may travel abroad to visit the grave or memorial site using a no-fee passport. Since the validity of a no-fee passport is five years, it may be used again for later trips during that tenure, if the purpose of travel remains the same.
No-fee passports are also used by the dependents or authorized relatives of persons traveling on a no-fee passport. However, such dependents or authorized relatives need to have their own no-fee passports.
American seamen, while traveling abroad for official duties aboard an American flag vessel, also use no-fee passports. Also, employees of the American National Red Cross traveling abroad as members of the armed forces use no-fee passports.
