Registration is now open for the Fall 2025 OISS ITIN Workshops! Registration via Calendly is required.
International stipend recipients and other foreign nationals* who need an Individual Taxpayer Identification Number (ITIN) are invited to attend this 1-hour OISS workshop. During the workshop, OISS staff will review the ITIN application process and issue letters to certify the identity and foreign status documents of attendees as required by the Internal Revenue Service (IRS) for the ITIN application. Attendees can then mail their application to the IRS rather than applying in-person with the IRS Taxpayer Assistance Center (TAC).
*If you already have an SSN, you do not need an ITIN.
