OPT unemployment days
Counts calendar days, weekends and holidays included, from the OPT start date on your EAD (the Actual OPT Start Date in SEVIS). The limits are 90 days on post-completion OPT and 150 in total with a STEM OPT extension (8 CFR 214.2(f)(10)(ii)(E)).
Your dates are only used to do this count. They aren't saved or sent to any AI model.
