Does it matter if Eligible Family Members (EFMs) arrive on the exact same date as the employee? Would it impact per diem if they arrive a day or two later?

Because TDY Rentals uses the authorized individual’s lodging per diem benefit to provide our services, then per diem would decrease if EFMs travel from post after the Direct Hire’s (DH) authorized HSTA begins by the number of days from the HSTA start date. This is because you cannot claim TDY before you are physically on TDY! If the employee or EFMs travel before the authorized HSTA dates, then TDY Rentals utilizes the full per diem rate for the entire duration of your TDY.
