OPT (Optional Practical Training) allows 12 months of work post-study, extendable to 36 months total for STEM graduates (a 24-month STEM extension on top of the initial 12 months). CPT available during studies. OPT authorization requires filing Form I-765 with USCIS and is tied to the student's field of study. The current USCIS filing fee for Form I-765 is $470 if filed online, or $520 if filed on paper. Specific application timelines, fees, and eligibility rules should be verified directly with USCIS, as immigration policy and fees change over time.
