The "Border Safety and Security Act of 2023" would give the Sec. of DHS the authority to suspend the entry of illegal aliens to achieve operational control of the border during a crisis or surge. Additionally, H.R. 29 requires the Secretary to stop entries if DHS cannot return them to the country they entered through (like Remain in Mexico), or detain aliens until their hearings. Finally, H.R. 29 allows states and municipalities to sue the administration for not following the required suspension mentioned above.
