Duration of Status ("D/S")
Often noted as "D/S" on the I-94 card, Duration of Status refers to certain situations where the length of the period of legal stay is determined by something other than USCIS assignment of an ending date to the approved period of stay. This is most commonly seen with F-1 and J- visas, where the length of stay is determined by the duration of the educational (F-1) or exchange visitor (J-1) program in which the foreign national is enrolled. Contrast this with H-1B or L-1 visas, where the length of the authorized period of stay is determined by USCIS or the Department of State at the time the petition is granted.
