Travel Information

The following is a list of travel requirements for your Jefferson Science Fellowship.

1. All travel requires submission of a Travel Authorization (TA) form prior to travel. All International travel requires a JSF International Travel Worksheet. These forms can be found on the Jefferson Fellows Travel Information web page. You must use a separate Travel Authorization form for each trip. Any changes to the approved TA must be reported to as soon as possible.

2. The Travel Authorization form must be signed by you and your USAID/State Department Supervisor. We will request approval from the AOR/COR and NAS Financial signature. The Travel Authorization form should be submitted by email no later than 1 week in advance for domestic travel and 2 weeks in advance for international travel. International travel requires additional authorization from the National Academies’ Office of Contracts and Grants which can take up to five business days.

3. An approved Travel Authorization authorizes you to travel and incur necessary expenses in accordance with applicable laws and regulations. All expenses that are approved on the Travel Authorization and require reimbursement must adhere to the National Academies and Federal Government policies, regulations, and laws. Expenses that do not comply with the above and not listed on the TA will not be reimbursed.

4. A Travel Authorization form must include your full name, cellphone number, e-mail address, date of birth, gender and completed cost estimate section. Be sure to include the date(s) of travel, all meeting dates, purpose of travel and itinerary. When necessary please provide additional details in the body of the email. A Travel Authorization that is missing information will delay the approval process.

5. Cost estimates should be as accurate as possible and must include any expense for which you plan to request reimbursement from the National Academies. Expenses claimed on the Travel Expense Report that were not listed on the approved Travel Authorization form will require justification and additional approval. This will delay the reimbursement process.

6. Lodging and meal expenses are reimbursed on an itemized, actual cost basis. Costs must not exceed the federal per diema allowance which can be found on the GSA website for domestic travel, the U.S. Department of Defense website for travel to Alaska, Hawaii and US territories, and the U.S. Department of State website for international travel. Expenses that exceed the per diem will not be reimbursed. Travel dates are typically the day before and day after the meeting dates. Per diem for travel days is calculated at 75% of the daily per diem. Expenses that exceed per diem will not be reimbursed.

7. Domestic lodging per diem rates do not include hotel taxes. Domestic hotel taxes are claimed and reimbursed as a separate expense. International per diem rates include hotel room rate and hotel taxes.

8. The National Academies requires that you use Omega World Travel (OWT) for both domestic and international travel. You may contact Omega World Travel Monday through Friday 8:30 a.m. to 5 p.m. EST at 866.740.0627 or email to make your travel arrangements.

9. OWT will provide you with an estimate of airfare and will assure that travel complies with FAA regulations. You may contact OWT at any time, but will not be able to book travel until your TA has been approved.

10. Allowable costs for lodging and meals are based on the prescribed maximum per diem rate established by the United States government for each location within or outside of the United States. Domestic (including Hawaii, Alaska, and United States Territories) per diem rates may be found at Foreign per diem rates may be found at Expenses that exceed per diem will not be reimbursed.   

11. When traveling by air, note the Fly America Act requires that you travel on a US-flag carrier whenever such carriers exist between points of travel. Omega World Travel can advise you on the requirements of the Fly America Act and will ensure that your travel does not violate federal travel regulations.  

12. Travel within 50 miles and under 12 hours from your DOS/USAID office is considered "local" travel. For approved local travel, you may be reimbursed for transportation, registration fees (if applicable), and any tolls and/or parking expenses incurred as part of your travel. Lodging and meals are not allowable expenses for local travel. All receipts required for local travel.

13. Use of a rental car requires prior approval. Please include the justification for the rental car on the Travel Authorization Form. When you book a rental car with Omega, it will be billed directly. By using Omega World Travel, you will automatically be insured by the National Academies. The cost of additional insurance is at your own expense. Gas receipts must be submitted with the travel expense report regardless of amount.

14 Should you choose to use your personal vehicle (POV) rather than a commercial airline, you will be reimbursed at the current government mileage rate plus any applicable tolls and/or parking expenses. Gasoline costs are included in the government mileage rate and will not be reimbursed separately. Reimbursement for travel by POV is limited to the cost of a comparable airfare.

15. When personal travel is combined with official State Department travel, any change in travel cost must be documented by Omega World Travel. Any increase in travel cost, including airfare and applicable change fees, as a result of combining personal and business travel is your financial responsibility. Personal travel days will not be covered under per diem.
