Act of Congress

An act of Congress is a statute enacted by the United States Congress. Acts may apply only to individual entities (called private laws), or to the general public (public laws). For a bill to become an act, the text must pass through both houses with a majority, then be either signed into law by the president of the United States, be left unsigned for ten days (excluding Sundays) while Congress remains in session, or, if vetoed by the president, receive a congressional override from 2⁄3 of both houses.
