Trotters boss Gary Megson has been a long-term admirer of the winger and is now close to agreeing a deal.
A fee in excess of £2million has been mooted for the 21-year-old, who currently plays for FC Seoul in his homeland.
He left the South Korean capital on Monday morning to travel to England to hold discussions over personal terms and undergo a medical with Bolton.
And the highly-rated youngster is hoping that he can return to Korea with positive news regarding a switch to the Premier League.
"A deal has yet to be signed, but I will try to come back with good results," Lee said.
Lee scored and won a penalty in Seoul's 3-1 win at Gangwon FC in the K-League on Sunday night, and afterwards said he has decided to make the move to England.
"This could be my last match for Seoul and I am happy I could score," he said.
"I had considered the transfer options several times because we (FC Seoul) have a good chance to be number one in Asia and Korea.
"But I wanted to accept this challenge and such chances don't come often."
FC Seoul have confirmed that they are ready to sanction Lee's move to the Reebok Stadium despite the domestic season being underway.
A club spokesman said: "We have decided to transfer Lee to Bolton, considering his promising future, even though the league is in full swing."
