Possible denial of any entry into the U.S. for a period of three years, if the student has been out of legal status from 180 to 364 days. Possible denial of any entry into the U.S. for a period of ten years, if the student has been out of legal status for 365 days or more. All F-1 students who would like to be employed must apply for and receive written authorization before beginning any employment. Employment without written authorization will cause the student to be out of legal status. Dates of employment are kept in both Social Security records and in the Immigration and Naturalization Service forms I-9 kept by each employer.
Unauthorized employment is very difficult to hide.
The regulations on authorized and unauthorized employment are quite clear and the instructions have been provided to each student. Therefore, the International Student Advisor will not back-date employment authorizations. We will not authorize employment already undertaken or already completed. No retrospective permission or recommendation for employment authorization will be given.
