F-1 - Extensions of Optional Practical Training

Most F-1 foreign students studying in the United States are eligible for Optional Practical Training (OPT) at the conclusion of their studies. This OPT is granted for a period of one year, and requires that the student work in a field related to the student’s major area of study. Some students are also eligible for OPT before they complete their course of study, but times in OPT before completion of their studies is deducted from the one year of OPT after the conclusion of their studies.

Students who major in certain majors in science, technology, engineering, or math, are eligible to extend their OPT for an additional 17 months as long as they comply with all other OPT requirements and their employer is using E-Verify to confirm employment eligibility of its new hires.

US Immigration and Customs Enforcement has published a list of the majors that qualify for the 17-month extension of OPT. The current list of majors, in alphabetical order is:
