Zaha, 20, will play for England under-21s against Sweden on Tuesday and will tell the Football Association he is fully committed to the Three Lions.
The exciting winger, now on-loan at Crystal Palace, has been in a tug-of-war between Ivory Coast and England as he is eligible to play for both countries.
He was born in the west African country and lived there until he was four but despite feeling proud of his parents' heritage, the importance of England in giving him a chance in professional football proved crucial.
A source said: "Wilfried wants to play for England. It's been difficult for him because he knows what Ivory Coast means to his family and he even had Didier Drogba calling to ask him to play for them.
"But England has been a massive part of his life. It's what he knows, the country has been his home for nearly all his life and they're who he wants to play for."
