The 2018/2022 bid process is unique in that two World Cup hosts will be selected at the same time. Their selection by FIFA's executive committee with take place in December 2010.
FIFA set out the minimum requirements to host: about 12 stadiums holding at least 40,000 fans for group matches, with one stadium of at least a capacity of 80,000 to stage the opening match and the final.
The requirements and timetable were sent to all eligible national associations. The 2018 World Cup cannot take place in Africa or South America and the 2022 World Cup cannot take place in South America.
Since the World Cup cannot take place in the same confederation two times in a row, it is expected that one of the two World Cups would go to a European nation and therefore the other would have to go to a non-European nation.
European countries bidding include England, Russia, Belgium-Netherlands-Luxembourg and Spain-Portugal. Potential U.S. competition from non-European countries are Australia and Qatar.
Other bids could come from the China, Japan, Mexico and Canada.
