This legislation aims to limit federal funding for infrastructure projects to certain state political subdivisions. Specifically, it prohibits the Secretary of Transportation from obligating or awarding funds for projects, such as highway construction, to any subdivision that does not implement a policy requiring notification to the Secretary of Homeland Security. The required policy mandates that an entity or official of the political subdivision must notify the Secretary of Homeland Security at least 48 hours before releasing an alien from custody or detainment. This notification is necessary if the Secretary of Homeland Security has determined the alien is not lawfully present in the United States, and has also informed the detaining entity of this status at least 48 hours prior to the release, provided the alien has been in custody for at least 48 hours. Such a policy must be in effect within one year of the Act's enactment to avoid the funding limitations.
