Typically new members of the credit union become citizens having suretyship or recommendations from their friends - members of the credit union. Cooperation between credit unions, how they would not have been named, took place always, from the moment when the movement moved outside one credit union. The main advantage of credit unions consists in transparency, controllability, governance for shareholders. Until the mid-XX century, credit unions in the United States had little assets that did not exceed, as a rule, 100 thousand dollars Credit unions, like today's credit unions, emerged in the 19th century in Germany as a result of crop failure and famine. U.S. credit unions have another significant difference from the credit cooperatives of farmers: the first have major proportion of short-term loans, the second - long and mostly in real estate. A potential new member of a credit union must submit a recommendation of shareholders in which the referee becomes a warrant of a future member of the credit union.
