The 21-year-old striker joins the Blues having previously played for AFC Rushden & Diamonds, St. Neots Town & Cambridge United.
Speaking to WaterfordFC.ie, Prince said:
“When I arrived here from the UK, I had to isolate. I had to train in my accommodation but found myself getting fitter and fitter.
“It’s been quite nice here, everybody has made me feel right at home. It’s nice to be here in the Sunny South East. It’s been great training.
“The works not done yet, I need to get sharper. I’m looking forward to improving my fitness and performance over the next few weeks. I’m feeling fitter and everything is coming together.
“Training here is tough but that’s been really enjoyable. I’m really looking forward to working under Kevin and Mike. I sat down with them, they said we’ll be pushing here to do very well here. They’ve been hugely positive so I’m just anxious now to getting started.
