Travel outside the continental United States is reimbursed based on the maximum per diem allowance established by the U.S. Department of State. The foreign per diem rates are published monthly. Expenses must be converted to American currency based upon the exchange rate in effect during the period of travel.
Foreign travel rates provide for lodging costs up to a maximum amount and an allowance for meals and incidental expenses. Meal per diem rates may be broken down into breakfast and dinner if needed (20 percent of total meal per diem for breakfast and 80 percent total per diem for dinner).
