English Language Unity Act of 2025

S 542, the English Language Unity Act of 2025, designates English as the official language of the U.S. federal government. It requires all federal government functions - such as laws, regulations, and public communications - to be conducted in English, with exceptions for national security, census work, public health, and Native American language preservation. The bill also mandates that naturalization ceremonies be held in English and that applicants demonstrate understanding of foundational U.S. documents like the Constitution. This directly affects federal agencies, naturalization applicants, and government communications, while preserving existing language rights under specific circumstances.
