Understanding This Page

The Federal Register is the daily journal of the U.S. government. Proposed rules invite public comment before becoming law. Final rules have completed the comment process and are (or will become) legally binding. FRTracker extracts obligations from these documents—the specific things people or organizations must, may, or must not do.
