What it does
This bill amends federal law to explicitly prohibit members of the Armed Forces and National Guard from being ordered to enforce immigration laws. It codifies a restriction aligned with the Posse Comitatus Act, which generally bars the military from domestic law enforcement, by adding new sections to titles 10 and 32 of the U.S. Code that make clear the military cannot be deployed for immigration enforcement or support.
Why we flagged it
The bill reinforces the Posse Comitatus Act by explicitly codifying a prohibition on military deployment for domestic immigration enforcement, protecting the constitutional separation of military and civilian law enforcement.
What the text implies
- Clarifies ambiguity in whether National Guard units operating under state control (Title 32) are subject to Posse Comitatus restrictions, potentially limiting governors' ability to deploy Guard for immigration enforcement without federal authorization.
- May constrain executive flexibility during border emergencies or mass migration events, as military support for immigration enforcement would require legislative authorization rather than executive order.

Who it affects
The bill protects citizens and non-citizens alike from military involvement in domestic immigration enforcement, preserving the constitutional separation between military and civilian law enforcement. It reinforces limits on executive power to deploy armed forces for domestic policing, a foundational democratic safeguard.
