Applying for a Social Security Number (SSN)

The purpose of a Social Security Number (SSN) is to help the government track of an individual's earnings in the U.S. for tax purposes. Once you are offered a job, you will need to apply for a SSN from the Social Security Administration (SSA). Eligibility for an SSN is based on the offer of paid employment, and regulations require you to provide valid employment offer letter and authorization from Visa & Immigration Services or USCIS to apply for a SSN. You must apply for an SSN in person at a local Social Security office. Provide originals and copies of the following documents to verify your age, identity, immigration status, and employment eligibility:

Please Note:

  • The SSA Office is extremely busy, so it is highly recommended that your arrival a little before the office opens. 
  • You cannot request Social Security Number over the phone, and it can take several weeks to receive the card in the mail. 
  • Social Security fraud is a serious offense. If you are offered on-campus employment and receive a SSN without intending to honor the employment arrangement this may be considered fraud. You must contact your on-campus employer immediately if you are unable to work.
