Jairo Pachon of Eurodata Sport added: "The United States provide us with similar climate and time zones as we will encounter in Brazil and more importantly, provide us with world class facilities for both training and accommodation, for our players' comfort.
"This will give us the opportunity to provide the right atmosphere for our players as well as afford them quality training facilities ahead of the FIFA World Cup."
The friendly against the United States is meant to the Americans to test an African opponent before they take on Ghana at the World Cup.
