On September 14, 2026, a U.S. District Court Judge issued a preliminary injunction on the published rule Establishing a Fixed Time Period of Admission and an Extension of Stay Procedure for F and J students. This order temporarily pauses the implementation of the rule until the court issues a further decision. The visa status of F&J visa-holders remains unchanged. ISS is closely monitoring this situation and will provide more information and guidance as it becomes available.
Any student who will work in the U.S. must apply for a Social Security Number. The employer must use the SSN to report wages and taxes to the Internal Revenue Service (IRS) and Social Security Administration (SSA). F-1 students are eligible to apply for an SSN after they have received an offer of employment that meets SSA standards.
UB's Office of the Registrar must get your correct identifying number to file certain information returns with the IRS. For students, this will be your social security number (SSN) or, if you are not eligible to obtain an SSN, your individual taxpayer identification number (ITIN).
After receiving your SSN, you must report it to the University using Form W-9(S). This form is also used for students who need to provide or correct their SSN or ITIN on file.
Contact the Office of the Registrar for assistance.
Social Security numbers are not general purpose ID’s. If a business representative or service provider asks you for a Social Security number, carefully consider if it's necessary.
You should not need a Social Security number to:
The only exceptions should be business providers who require a credit check before doing business with you or opening an online account for you.
If you are not working in the U.S., you also do not need a Social Security number to submit tax forms (e.g. Form 8843) to the Internal Revenue Service, which is the U.S. government’s tax agency. For this purpose, you should apply instead for an Individual Taxpayer Identification Number (ITIN). For information on how to do this at UB, please contact Human Resources' International Services.
In order to work in the U.S., you will need a Social Security Number. To obtain one, you will have to document that you are eligible to work in the U.S.
A letter from your on-campus employer on the employer's letterhead verifying that you have secured employment. If it is not on original office letterhead, it must have an original signature in blue ink.
