The purpose of this legislation, known as the Deportation Acceleration Act, is to streamline the process for deporting noncitizens who have been convicted of crimes. It aims to enhance cooperation between various government agencies and expand the criteria under which noncitizens can be deported, making it easier and faster to remove individuals from the country if they have committed certain offenses. Key provisions of the Act include mandatory real-time reporting of criminal convictions for noncitizens to the Department of Homeland Security.
