The Republic of Ireland international, who played every game for the Green Army at Euro 2012, has been without a club since May, having been released from the books of Premier League newcomers Leicester City.
Despite being just 29, and holding 37 senior caps to his name, the former Preston and Middlesbrough man has found opportunities hard to come by, with clubs unwilling to break their budgets with the tightening grip of financial fair play in full force.
A deal to take him to Huddersfield collapsed at the last minute, with then-manager Mark Robins leaving the club with the deal set to be finalised. Upon Robins’ departure, the club decided against taking the central defender on a permanent deal.
The player is aware that the situation in England is not favourable for out-of-work players, and speaking to Irish media outlet The Herald, St Ledger revealed that a move to the USA could be an option, with clubs interested in his talents.
"I need to go and prove myself, go and play somewhere so I can try and get back to where I was," he said. "It's tough out there at the moment and the financial situation across the scene in England isn't great.
"There have been a few sniffs from the USA so I would consider that but their transfer window closes next week. I could possibly go there, play the few few months of their season to prove myself and come back to England. It's a waiting game and it's frustrating.
"It's all about budgets and financial fair play now. Managers have spent their budgets and if they bring in a new player, someone else has to leave so they can balance the books. That's the way it is. I have never seen so many younger players, and older professionals, out of work in all the time I have been playing. It's a lot more difficult to get a club and a contract now.”
A successful short-term spell in MLS could be a useful way for St Ledger to both return to match fitness, and alert English teams to his availability. Despite having played just twice for the Foxes as they stormed to the Championship title last season, St Ledger still has a reputation as a talented Football League level defender, and it would come as no surprise to see him snapped up in the near future by a club searching for promotion to the Premier League.
