To amend the Immigration and Nationality Act to codify the Optional Practical Training program.

This bill aims to make permanent the rules for Optional Practical Training, which allows international students to work in the United States after completing their studies. It directly affects F-1 visa holders by codifying their ability to gain up to 24 months of work experience related to their field of study, or up to 48 months if they studied science, technology, engineering, or mathematics. The legislation also directs the Department of Homeland Security to classify nursing as a STEM field, thereby extending the longer work authorization period to nursing graduates. By adding these provisions to federal law, the bill ensures that these work opportunities remain consistent and legally defined for future students.
