This bill matters because it changes how the U.S. government handles non-citizens deemed national security risks. If passed, it would remove the government's current flexibility to decide whether or not to deport someone whose visa was canceled for security reasons, making it a mandatory action.

This means that if a non-citizen's visa is revoked due to links to terrorism, espionage, or other threats to the U.S., they would automatically face immediate deportation proceedings. It aims to ensure a swift response to perceived security threats by requiring the government to act without delay, rather than allowing for other considerations that might delay or prevent removal proceedings from starting. If it doesn't pass, the Secretary of Homeland Security would retain the current discretionary power.
