When
you travel for the government, you will be able to get a cash advance
for anticipated out-of-pocket reimbursable expenses before you leave.
While traveling, you must use a government travel charge card for all
official travel expenses unless, (1) a vendor does not accept the travel
charge card; or (2) the Administrator of GSA has granted an exemption
(see FTR Section 301-70.704); or (3) your agency head or his/her designee
has granted an exemption. When you return, submit a claim for reimbursement
of the allowed expenses incurred while on travel. You will use the reimbursed
amount to pay the travel charge card bill, or it may be sent directly
to the card-issuing bank if your agency has this paying option in place.
