The Department of State Standardized Regulations (DSSR) govern overseas allowances for U.S. government civilians. Start with Overseas Allowances (COLA + Hardship + Danger Pay) for all three on one page, or open a single allowance type. (For DSSR foreign per diem, see the DSSR section under Per Diem.)
Every rate on these pages is available as normalized JSON through the Allowances API — current and historical, by location and effective date.
