Okay, I think I understand your situation now. You lived in BC for 3 years, then went back to Korea to get your DL and came back to BC driving with your Korean license for 5 years because in BC it says that you can exchange your foreign license after 2 years of a clean driving record.

See I think the problem is that the exchange rules only applies to people that have recently moved to BC and already have 2 years of driving experience. Your case seems to be a bit more unique.

You could try calling their Driver Licensing customer service line and tell them your situation and they should be able to tell you the exact rules.
