In some cases it may be advisable to depart the U.S. and re-enter with a new I-20, rather than applying for reinstatement. You may do this by obtaining a new I-20 from the ISSS, then departing the U.S., paying a new SEVIS fee, applying for a new F-1 visa if the F-1 visa stamp in your passport has expired, and returning to the U.S.
Note that students who violated status are not eligible for automatic visa revalidation. A re-entry to the U.S. after a status violation is viewed by Immigration as "initial attendance" in F-1 status. As such, you are bound by restrictions placed on new students, such as the academic year waiting period for eligibility for practical training.
To request a new I-20 for travel and reentry complete the online application for a new I-20.
You must discuss your case with an ISSS adviser prior to a new I-20 being issued. Please see http://www.temple.edu/isss/home/hours.html for information on how to schedule an appointment with an ISSS adviser if you cannot come during walk-in hours.
