The Department of Homeland Security (DHS) proposes to amend F-1 nonimmigrant student visa regulations on optional practical training (OPT) for certain students with degrees in science, technology, engineering, or mathematics (STEM) from U.S. institutions of higher education. Specifically, the proposal would allow such F-1 STEM students who have elected to pursue 12 months of OPT in the United States to extend the OPT period by 24 months (STEM OPT extension). This 24-month extension would effectively replace the 17-month STEM OPT extension currently available to certain STEM students.
I am currently in US on H1-B and wanting to switch to F-1? How long does this process usually take? Is there an option for adjustment of status or do I have to leave the country to get the F-1 stamp?
If you are maintaining H-1 status on the date your H-1 to F-1 change of status application is received by USCIS, you can apply for H-1 to F-1 change of status within USA. Check with your school. They should be able to guide you.
