The main purpose of this legislation is to update the Immigration and Nationality Act to provide certain long-term residents of the United States with access to a specific immigration benefit. This change aims to recognize and support individuals who have been living in the U.S. for an extended period, allowing them to apply for legal status under more flexible criteria. Key provisions of the legislation include a change in the eligibility requirements for the immigration benefit. Previously, the law required individuals to have entered the United States before January 1, 1972, to qualify.
