The report examines DHS oversight of the OPT program, which allows foreign students to work in the US during and after academic study. It finds that DHS has not identified or assessed risks of fraud or noncompliance by schools recommending OPT or students approved for it. DHS also lacks complete information on OPT students' employment and cannot fully ensure they maintain legal status while working. The report recommends DHS identify and assess OPT risks, and require schools and students to report more employment information.
