On May 10, 2016, new immigration regulations went into effect with respect to foreign national students working in the US. Specifically, the regulations expand opportunities for the extension of post-completion work authorization (optional practical training, or “OPT”) for students who complete a STEM (Science, Technology, Engineering or Mathematics) degree. These opportunities will require additional reporting requirements and other responsibilities for employers and the F-1 student employees prior to, during and following STEM OPT employment.
