On April 8, 2008, the U.S. Department of Homeland Security published an Interim Final Rule, effective immediately, that provides for additional Optional Practical Training (OPT) work authorization for foreign nationals in F-1 student visa status who would otherwise be limited to twelve months of OPT.  The new regulation provides two types of prolonged OPT: (1) an automatic extension of OPT to bridge the “cap gap” between an employee’s OPT expiration date and the October 1st date when an approved cap-subject H-1B petition takes effect; and (2) a seventeen-month extension, upon application, of OPT for graduates of U.S. degree programs in Science, Technology, Engineering and Mathematics (“STEM” degrees) who have jobs related to their field of study with employers who are enrolled in the government’s E-Verify program.
