In 1908. the spread of credit unions has reached the United States. In 1935 President Roosevelt signed the state Charter on credit unions, which became a law. Specialization of credit unions to provide financial services to its shareholders requires a particularly strict regulation of membership and acceptable activities. When organizing the credit union it is important that people know each other and know the extent to which each of them is trustworthy. Is necessary that all shareholders of the credit union were members of a single community, would know each other well enough to enjoy mutual trust. Contributions from of shareholders in credit unions in no way can be considered as borrowed funds, they come from the shareholders and for the shareholders and can not be used to provide services to third parties. Unlike banks, in order to use the services of a credit union, you have to become its member, having written an application and having paid thus shares and membership fee. Today, the World Council of Credit Unions is represented as members four regional confederations and twelve national associations.
