304-3.19—Are there other situations when I may accept payment from a non-Federal source for my travel expenses?

Yes, you may also accept payment of travel expenses from a non-Federal source under the following authorities, in addition to this part:
(a) Under 5 U.S.C. 4111 for acceptance of contributions, awards, and other payments from tax-exempt entities for non-Government sponsored training or meetings (see regulations issued by the Office of Personnel Management at 5 CFR part 410 ).
(b) Under 5 U.S.C. 7342 for travel taking place entirely outside the United States which is paid by a foreign government, where acceptance is permitted by your agency and any regulations which may be prescribed by your agency.
(c) Under 5 U.S.C. 7324(b) when payment is for travel to be performed for a partisan rather than an official purpose in accordance with the Hatch Act (5 U.S.C. 7321-732 6); or
(d) Pursuant to the applicable standards of ethical conduct regulations concerning personal acceptance of gifts. For example, under 5 CFR 2635.204(e), which authorizes executive branch employees to accept gifts based on outside business employment relationships. (Note: You may also be able to accept attendance at (but not other travel expenses to) a widely attended gathering under 5 CFR 2635.204(g)(2) when the gathering is not a meeting, as defined in this part, and you are not attending in your official capacity.)
