Social Security Number

Applying for a Social Security Number (SSN)

The only way to receive a Social Security Number within Washington State is for the purpose of your employment. This means that you will first need to find work before you can receive this number. Please note that a Social Security Number is mandatory in order for you to get paid. Below are the steps on how to get your Social Security Number.

How to Apply

F-1 Students with On-Campus Employment

To apply for a SSN as an F-1 student for an on-campus job, you will need to provide documents that show your identity, age, citizenship, and status as a lawful alien. You will need to bring the following items with you:

  • Passport
  • Current I-20 with signature on page two
  • Printout of I-94 (available through the I-94 website)
  • Letter from the ISC describing why you need a SSN (instructions on how to request this letter listed below)
  • Letter from your supervisor (employer) on department letterhead stating your job title and signed by your supervisor
  • Complete an application form (Form SS-5) that you must fill out at the SSA office or download from the internet. This form is not available at the ISC.


Once your application is filed with the officer, they will give you a receipt. They will perform a background check, and your Social Security card will be mailed to the address you provide within four to six weeks. Normal processing takes about four weeks.

Requesting a SSN Letter from the ISC

  • Provide a copy of a letter (on official letterhead) from your employer that states:
    • Your job title

    • The number of hours you will be working
    • Your start date
  • Update your contact info on SU Online
    • We will be checking this information before issuing a letter
  • Drop the Letter request and the letter from your advisor at the ISC (PAVL160)

Once all the documents have been dropped at the ISC, your letter will be ready for pick up within 3-5 business days. You will get an email from your advisor at your SU email saying your letter is ready.
