If you are employed at OSU you will need a Social Security Number (SSN). If you don’t have an SSN you will need to apply for one from the Social Security Administration. This is done by completing Form SS5, Application for SSN.
You can apply in person at the local Social Security Office. The Form SS5 is available on the Internal Revenue Service website at www.irs.gov, click on Forms and Publications, then Form and Instruction Number, and scroll through a listing of form numbers until you see Form SS5. You will receive a receipt from the Social Security Administration at the time of application. Approximately six to eight weeks later you will receive the actual SSN. You will also need a letter from the Office of International Affairs with the SS5.
If you are not employed by OSU (for instance, only receiving a scholarship or fellowship with no work or service requirement you are not eligible for an SSN and you will need to apply for an ITIN (Individual Identification Number) from the Internal Revenue Service – see below, “What's an ITIN Number?”.
