A Social Security number is a unique, identifiable number assigned to an individual for tax purposes. If you have income from a U.S. source, you will need a Social Security number.
Once you have a Social Security number, the number is unique to you forever. If you leave the country and return at a later date, you will have the same number. It is very important to protect your Social Security number.
Do I Need a Social Security Number?
Not every international student needs a Social Security number; you can only apply for one after you are offered a job. Depending on your visa, international students are only eligible for certain types of employment. If you have any questions, please contact the Office of International Services.
You do not need a Social Security number to open a bank account, apply for a driver’s license or sign a lease. While some representatives may ask for one, you can tell the representative that you are an international student and are not given a number unless you are employed.
You can obtain a letter from the Social Security Administration stating that you do not have a Social Security number. Keep this letter in a place that you can use it again if asked in the future about your Social Security number. To obtain this letter, bring the following to a Social Security Administration office:
