As noted in the FSOA invitation letter, candidates are guaranteed an appointment only within the dates associated with their Foreign Service Officer Test (FSOT) cohort. While the invitation is valid for 12 months, if a candidate does not schedule the Foreign Service Officer Assessment for one of the dates offered as part of their FSOT cohort, we cannot guarantee an alternative assessment date. Candidates may contact reschedule@state.gov to have their name placed on a waiting list, and if an assessment date becomes available, the candidate will be contacted. Please note that candidates on the waiting list are offered rescheduling on a first come, first served basis.
