Federal laws apply throughout the United States and include, for example, laws related to immigration law, bankruptcy law, social security and supplemental income laws.
There are 50 states and several commonwealths and territories within the United States. Each has a different system of laws that apply within the state, commonwealth or territory to areas such as criminal justice, welfare and public assistance, real estate, business contracts, and more.
Each state, commonwealth and territory is made up of counties, cities, municipalities, towns, townships and villages. Some local governments have their own laws related to areas such as zoning and local safety.
