The 18-year-old, who holds dual nationality after being born in Kingston to Jamaican parents, has represented England at every level from under-16 onwards and won his first senior cap for Roy Hodgson's side in last month's 4-2 defeat in Sweden.
He remains eligible to play for the country of his birth as the Stockholm fixture was only a friendly, but has no plans to abandon England.
Quoted in several newspapers, he said: "It was a dream come true (to play against Sweden). As a 15-year-old I can remember sitting at home and praying to get an under-16 call-up, so to be getting a senior call-up a few years later was one of the best things that ever happened to me. I want to keep driving on and do a bit more."
He added: "Obviously I've got Jamaican roots but no-one tried to put any pressure on me, which was the good thing. But I couldn't turn my back on England because I've grown up through the English youth system and progressed from there.
"I couldn't just switch over. So it was a good thing for me to be called up and make my debut. It's 100 per cent going to be England from now on."
