STEM OPT Extension Application to USCIS Checklist
USCIS allows STEM OPT Extension applications to be filed online. You have the option to submit your application via regular mail or file online. The documents below are required for your STEM OPT Extension application, whether you file online or via regular mail (unless otherwise noted). If applying by mail, you should make copies of documents; do not send
originals. If applying online, the online application will ask that you upload these documents to the online application. In both cases, make sure documents are clear and readable. If filing online, please review the Online Filing Webpage, and ISSS' STEM Extension OPT Online Filing Guide.
