The Biden-Harris Administration is implementing new enforcement measures to increase security at the border and reduce unlawful crossings. These measures will expand legal pathways for migration and impose consequences for those who fail to use them. The Administration will surge additional resources to the border and region, scale up anti-smuggling operations, and expand support for border cities and non-governmental organizations. The actions are being implemented in partnership with Mexico and governments in the Western Hemisphere. The Administration acknowledges that these steps will not solve all the problems in the broken immigration system and calls on Republicans in Congress to support comprehensive immigration reform and border security measures.
