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. 7321–7326); 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.
