The main purpose of this legislation is to amend the Immigration and Nationality Act to increase the number of H-1B nonimmigrant visas available for skilled workers. The goal is to make it easier for U.S. employers to hire foreign professionals in fields where there is a shortage of qualified American workers. Key provisions of the legislation include raising the annual cap on H-1B visas from 65,000 to 130,000. This change aims to allow more skilled workers to enter the U.S. job market.
