While on 12-month post-completion OPT, you must report the start and end of your employment to SEVP (Student and Exchange Visitor Program) within 10 days of occurrence. You will be reporting and updating your employment information in the SEVP Portal.
The SEVP Portal is a tool that lets OPT students meet their OPT reporting requirements. The Portal allows OPT students to report their address, telephone number and employer information. The portal shares information with SEVIS, but does not give students direct access to SEVIS.

Only IASS has direct access to your SEVIS record, but you will be able to review and update your home/mailing address, telephone number, and employment information via the SEVP Portal. All data entered into the SEVP Portal will be automatically sent to SEVIS.
After you are approved for Post-Completion OPT you should received an email from do-not-reply.sevp@ice.dhs.gov up to 10 days after your OPT start date. If you do not receive it by then, you will have to request that IASS update your employment information on your behalf.
