And *nothing* changes the facts that:
a) IRCC is of the opinion that the OP's wife is already married
b) They have demanded proof that she isn't, particularly from South Korea
c) That's really hard to do
d) Korea makes it a criminal offence to hand out personal info in most cases - police certificates are an example
e) without knowing exactly why IRCC thinks OP's wife is married, it's hard to prove she isn't. Though if she were living in Korea at the time in question with (an abusive) ex-boyfriend, she may be able to obtain some kind of personal records on herself, unless she was a tourist
f) OP needs a lawyer.
