International students (F-1 status students) are only eligible to receive Social Security numbers when they have a job or job offer.
If you get a job, you must apply for a US Social Security number to be paid. Contact the Intercultural
Office for assistance in completing the application and to verify that you have all appropriate supporting documents (letter from Intercultural Office Director, Letter from Human Resources verifying job, Application, Passport, I-94, Visa, and I-20). The social security application form is available online or you can pick up an application in the Intercultural Office. The Intercultural Office will arrange a time to go to the Social Security Office if there are enough people to make the trip cost effective. You need to plan on going to Social Security in the month that you are hired.
Once your receive your Social Security Number, it is your number for the rest of your life! Don't lose the card as it is difficult to replace. Keep the number safe and do not give this number out without knowing clearly why. There is a lot of identity theft in the USA and the Social Security number used in stealing identity.
