Guaranteeing the States Protection Against Invasion Act of 2026

This bill amends the Immigration and Nationality Act to empower the President to determine and proclaim that an invasion exists at the southern border of the United States. During such a proclaimed invasion, the President is mandated to suspend the entry of any alien who unlawfully enters or attempts to enter across the southern border. Furthermore, aliens who unlawfully enter during this period become ineligible for any relief, protection, or benefit under the Act that would permit them to remain in the United States, including asylum and withholding of removal. The bill specifies that there will be no court jurisdiction to review these ineligibility determinations, except for claims of U.S. nationality. It also makes aliens inadmissible and subject to immediate removal if they fail to provide required public health and security information during an invasion. The Secretary of Homeland Security is granted broad authority to repel, detain, expel, or remove aliens involved in the invasion, with these authorities ceasing upon a presidential proclamation that the invasion has ended.
