National Credit Union Administration (NCUA) - an independent federal agency, based in Washington (State of Columbia), established by the U.S. Congress to oversee the federal credit union system. In recent decades, many credit unions began to resort to such form of service as Credit unions are financial institutions, financial cooperatives of citizens, and in this capacity they are above all associations of people, not unification of capitals, which is typical, for example, for public companies. The right to use the services of the credit union have only its members.
