Social Security Number

A Social Security Number (SSN) is needed for employment in the United States. Students and scholars are eligible to apply if they are employed in the U.S. or have been offered a job. If you are paid in the U.S., you must have a SSN to file a U.S. income tax return. Students who do not have a job will not be eligible to apply for a SSN. Please refer to the Social Security Administration for more information about International Students and Social Security Numbers.

Application Process

You must apply at the Social Security Administration Office in Cheyenne, WY. You may not apply until one month after the beginning of the semester for a student, or until one month after your arrival for a visiting scholar. You should receive your social security number in the mail within 4-6 weeks after you apply.
