The main purpose of this legislative proposal is to officially establish the Optional Practical Training (OPT) program within U.S. immigration law. The OPT program allows international students on F-1 visas to work in the United States in jobs related to their field of study, both during and after their academic programs. This legislation aims to ensure that this program is clearly defined and protected under the law. Key provisions of the proposal include amendments to the Immigration and Nationality Act.
