With the formalities of the deal almost complete, the South Korean international is all set to pen a short-term contract with the Latics which will run until the end of the season - with the option of extending that agreement in the summer.
The midfielder had seen his free transfer delayed due to work permit problems, having not featured in 75 per cent of his country's fixtures in the last two years due to injury, but those problems appear to have been ironed out.
He has now headed home to put the finishing touches to the move, but Bruce is looking forward to getting the 25-year-old back in England and into Premier League action.
"He's had his medical and it looks as though his work permit will be granted," Bruce told the Wigan Observer.
"He trained again today (Tuesday) but has to go back home now to complete the paperwork.
"We hope he'll be able to come straight in to the squad, and he will be a good addition for us.
"He's a utility player, but I feel his best position will be in midfield.
"We have a deal in place that lasts until the end of the season, and then a two-year contract ready at the back end of that."
