Social Security Number
In the United States, a Social Security number (SSN) is a nine-digit number issued to U.S. citizens, permanent residents, and temporary (working) residents. The number is issued to an individual by the Social Security Administration. Its primary purpose is to track individuals for taxation purposes. Social Security numbers are available only to those international students and scholars who have secured employment in the U.S. If you have previously applied for and been granted an SSN, this number is yours for life. You should not apply for a second number.
Students and Scholars who are required to file a tax return, but who are not eligible for a social security number, may need to apply for an Individual Taxpayer Identification Number (ITIN).
If you will be employed while in the United States, you must apply for an SSN in person at the local Social Security Office. Before applying, you must check in with the International Center. After submitting the application to the Social Security Administration, you will receive a written notice with estimated processing time.
Students or scholars with on-campus employment must request a Social Security Number letter from the International Center. To do so, please contact the International Outreach Coordinator. Typical processing time for your letter is one to two business days after your request has been submitted. You will receive an email when the letter is ready to pick up.
Although an SSN may be requested for other services such as banking, utilities, cell phones, etc., it is only required for employment. For purposes other than employment, ask the service provider about acceptable alternative identification numbers.
