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.
