The Department of Homeland Security (DHS) is amending it F1 non immigrant visa regulations on Optional Practical Training (OPT) for certain students with degrees in Science, Technology, Engineering or Mathematics (STEM) from US institutions of higher education.
OPT is a period during which undergraduates (BS/BA) and graduate students (MS/MBA) with F1 status who have completed or have been pursuing their degrees for more than 9 months are permitted by the United States Citizenship and Immigration Services (USCIS) to work for 12 months on a student visa towards getting practical training to complement their education. On April 2nd 2008 DHS announced a 17-month extension to the OPT for students in qualifying STEM fields to be eligible for the 12-month permit. Any degree in any field of studies is valid. For the 17-month OPT extension a student must have received a STEM degree as listed on the USCIS website.
