Kennedy came through the West Ham youth system with England U21 captain Mark Noble and is now turning heads in the 'States with Lees-McRae College in North Carolina.
He said: "It's my dream to play professionally and I'd like to stay in the States. The game has really taken off there. But ultimately I'd love to come back to England and play for Millwall. I'm a huge Lions fan and to run out at The Den would be amazing.
"If I model myself on anyone it's Tim Cahill, who is a Millwall legend. I used to watch him and he was great at getting forward and scoring goals, so to emulate him would be fantastic."
Kennedy added: "I left West Ham and had a year at Chelsea but broke my leg. That ended it in England for me and I went to play in New Zealand. My brother was in America and he sent a video of me playing to a college coach in New York. They liked what they saw and invited me over. I was there for a couple of years before joining Lees-McRae in 2008.
"People in England don't know much about American college soccer but it's huge, with the finals shown on TV and big crowds turning up to watch. There's a lot of money put into it and I'd recommend it to anyone keen to try it."
