Social Security Number Application

Social Security Numbers (SSN) are generally assigned to people authorized to work in the US. International students in valid F-1 and J-1 status may apply for a SSN for on-campus employment or authorized CPT/OPT/AT employment. International students, F-1 or J-1, must obtain a signature from our office as part of the social security number application process. To obtain a signature from our office for your SSN application, please see instructions below:

On-campus employment students (assistantships/hourly jobs)

If you are employed by Purdue University, please contact your employing department business office or payroll center to request a Social Security Request DocuSign form for F-1/J-1 Students. Their office will complete the form which is routed directly to our office for our signature. ISS will receive the DocuSign form, review student’s record for F-1/J-1 compliance, print and sign document. ISS will email student when the signed document is ready for pick-up. SSA office requires the original document with wet signature from ISS for SSN application.

Optional Practical Training (OPT)

There is no need for additional signature from our office when your OPT is approved by US Citizenship and Immigration Services and you receive your employment authorization document (EAD). Your EAD and your valid I-20 show your employment eligibility.
