The heavyweight contender will take on Trevor Bryan in Miami on Saturday (11.06.22) in his second straight fight on American soil and is keen to raise his profile in the country.
Dubois told BoxingScene.com: “I think it’s good to fight [in the U.S.], to win over the American audience. That really makes me popular and world-known. This is where it’s at. I can’t wait to go in there and deliver."
The Brit fought in Ohio last August where he beat journeyman Joe Cusumano and says that his latest fight Stateside will be his best yet.
Dubois said: "It was a warmup. It was good to come over here and get a taste for what it’s like. Now I’m back for more.
"This is the big one. I’m looking forward to it. It’s a world title fight, the biggest fight of my life. I want to show him what I got. They’re sending me abroad. We’ll see where they send me next."
Dubois' promoter Frank Warren has suggested that it will be his last fight in America for the time being as he wants the star to return home to London.
He said: "We’re going back to the UK. He’s coming back to London. Win this and come back with the belt."
Dubois has pledged to make a "statement" in what he considers to be the most important bout of his career.
He said: "I want to make a statement in devastating fashion. By any means necessary, but I'm looking to make a statement.
"This is an important fight. It's a fight for my career and I've gotta fight my heart out, go in there and do the best I can and more. I've changed things up. We've made the necessary changes, so I'm all systems ready to go."
