Disambiguated questions and answers:
context: The United States Congress is the bicameral legislature of the federal government of the United States, and consists of two chambers: the House of Representatives and the Senate. The Congress meets in the United States Capitol in Washington, D.C. Both senators and representatives are chosen through direct election, though vacancies in the Senate may be filled by a gubernatorial appointment. Congress has 535 voting members: 435 representatives and 100 senators. The House of Representatives has six non-voting members representing Puerto Rico, American Samoa, Guam, the Northern Mariana Islands, the U.S. Virgin Islands, and the District of Columbia in addition to its 435 voting members.

context: The fifty American states are separate sovereigns, with their own state constitutions, state governments, and state courts. All states have a legislative branch which enacts state statutes, an executive branch that promulgates state regulations pursuant to statutory authorization, and a judicial branch that applies, interprets, and occasionally overturns both state statutes and regulations, as well as local ordinances. They retain plenary power to make laws covering anything not preempted by the federal Constitution, federal statutes, or international treaties ratified by the federal Senate. Normally, state supreme courts are the final interpreters of state constitutions and state law, unless their interpretation itself presents a federal issue, in which case a decision may be appealed to the U.S. Supreme Court by way of a petition for writ of certiorari. State laws have dramatically diverged in the centuries since independence, to the extent that the United States cannot be regarded as one legal system as to the majority of types of law traditionally under state control, but must be regarded as 50 "separate" systems of tort law, family law, property law, contract law, criminal law, and so on.

context: Federal administrative agencies, when granted the power to do so in a statutory grant of authority from Congress, may promulgate rules that have force of law. Agencies "legislate" through rulemaking—the power to promulgate (or issue) regulations. Such regulations are codified in the Code of Federal Regulations (CFR) and published in the "Federal Register". Rules of lesser effect are published in a host of forms, including manuals for agency staff and for the public, circulars, bulletins, letter rulings, press releases, and the like.

Long answers:
long_answer: Federal laws in the United States generally must pass through both houses of Congress. However, the Constitution sets out other ways federal laws can come into being, including treaties ratified by the Senate, regulations promulgated by the executive branch through federal administrative agencies, and case law originating from the federal judiciary. Below the federal level, each of the fifty American states has its own constitution, legislature, and courts with which to establish any laws that are not in the domain of the federal government.
