FY 2018 Per Diem Rates for Guam
Look up Per Diem Rates for foreign destinations set by the State Department
Traveler reimbursement is based on the location of the work activities and not the accommodations, unless lodging is not available at the work activity, then the agency may authorize the rate where lodging is obtained.
Unless otherwise specified, the per diem locality is defined as "all locations within, or entirely surrounded by, the corporate limits of the key city, including independent entities located within those boundaries."
Per diem localities with county definitions shall include "all locations within, or entirely surrounded by, the corporate limits of the key city as well as the boundaries of the listed counties, including independent entities located within the boundaries of the key city and the listed counties (unless otherwise listed separately)."
When a military installation or Government-related facility (whether or not specifically named) is located partially within more than one city or county boundary, the applicable per diem rate for the entire installation or facility is the higher of the rates which apply to the cities and/or counties, even though part(s) of such activities may be located outside the defined per diem locality.
Meals & Incidentals
The separate amounts for breakfast, lunch and dinner listed in the chart are provided should you need to deduct any of those meals from your trip voucher. For example, if your trip includes meals that are already paid for by the government (such as through a registration fee for a conference), you will need to deduct those meals from your voucher. Refer to Section 301-11.18 of the Federal Travel Regulation for specific guidance on deducting these amounts from your per diem reimbursement claims for meals furnished to you by the government. Other organizations may have different rules that apply for their employees; please check with your organization for more assistance.
