For routine IRIS staff and committee travel, IRIS will reimburse travel meals and incidental expenses (M&IE) on a per diem basis, using the applicable U.S. government rates. IRIS program travel (e.g., interns, experiment support) may have other guidelines, so please consult IRIS Financial Services (firstname.lastname@example.org) or your program travel coordinator for details.
The per diem rate is determined by the destination city as listed on the travel authorization form.
