Mexican venues under consideration are Monterrey, Guadalajara and Mexico City.

Canada narrowed its list to Montreal, Toronto and Edmonton.

The U.S. metro areas in the running are Atlanta (Mercedes-Benz Stadium), Baltimore (M&T Bank Stadium), Boston (Gillette Stadium), Cincinnati (Paul Brown Stadium), Dallas (AT&T Stadium), Denver (Sports Authority Field), Houston (NRG Stadium), Kansas City (Arrowhead Stadium), Los Angeles (Rose Bowl and the new NFL stadium), Miami (Hard Rock Stadium), Nashville (Nissan Stadium), New York (MetLife Stadium), Orlando (Camping World Stadium), Philadelphia (Lincoln Financial Field), San Jose (Levi’s Stadium), Seattle (Century Link Field) and Washington (FedEx Field).

In an agreement announced when the bid launched last year, the United States will stage 60 of the 80 matches, including all from the quarterfinals on, while Mexico and Canada will get 10 apiece. Twenty-three cities, including Washington and Baltimore, are in the running to become the 16 match venues. In all likelihood, 11 of the 17 proposed U.S. sites will make the cut. A decision is not expected for another two years.
