USCIS has updated its Policy Manual for STEM students under F/M nonimmigrant status. The new guidance allows one online class or three credits per session to count toward full-time study. It clarifies transfer rules, status changes, and eligibility for post-completion OPT during the 60-day grace period. The update also corrects the STEM OPT extension application period and addresses SEVIS status during study abroad. These changes are effective immediately for all pending and new requests.
