The U.S. government has ordered the suspension of H1-B visas for immigrants but not OPT.
While the Secretary for the Department of Homeland Security Chad Wolf in an interview said he is concerned about the OPT jobs being taken by foreign students, NBC News reported that DHS had sent recommendations restricting immigrant students to pursue the OPT training. However, the Homeland department has not restricted the F1 students to apply for the STEM OPT training as of 18 May 2020.
