As an international student you are unfamiliar with the Social Security numbers that Americans live by. Social security numbers are an important part of identification that Americans use for opening bank accounts, purchasing cell phones or renting apartments. As an international student you will not likely have a social security number. As an international student you will need a social security number if you choose to work on or off campus.  If you are interested in accepting employment, please see the International Student Coordinator for more information.

As a non-resident, you are required to file taxes with the International Revenue Service (IRS), even if you were not employed.  This form is called 8843.  If you have been employed in the US as an F-1 student, in addition to the 8843, you will also file 1040-EZ form which is for your income tax return.  International Student Services holds a tax seminar for international students prior to the April 15th deadline for filing taxes.  However, this seminar does not replace professional advice, and you are advised to use a professional tax service to assist in your filing process.  You may also call 1-800-829-1040 to speak with an IRS representative.  Please be sure to tell the representative that you are a non-resident for tax purposes.
