My wife left me to go back to korea and now lives with some nigerian guy in itawon I want to find her but how?

First, ask yourself these questions -

"To what purpose would it benefit me if/when I find my wife?"

"If I get lucky and find her, what would happen?" (Only you can answer this one)

"If I do find her, what would be the end result of finding her?"

Naturally, your reasons are your own.

If your wife left (walked out) the marriage, then there is no reasonable purpose at all for spending the money needed for airline ticket, lodging, transportation, and food for your going to Korea.

(If there was a confrontation between yourself and the Nigerian guy, you might also add medical expenses)

One thing to consider - The Nigerian people are getting a reputation of being criminal-related.

(There is a large Nigerian population within the Haebongchon area.)

My wife knows a person living in the Haebongchon area of Seoul; she constantly complains of all the criminal activity ongoing by the Nigerian population within Haebongchon.

This Haebongchon area is approximately 1 kilometer from Itaewon. Chances are good she is living within this area.

But, like other answerers, I would also suggest that you give up totally on her and move onwards and upwards with your life.

Nobody can honestly say they know how you feel; everybody's pain is unique.

But, when you finally make the decision to get her out of your life forever, you will start healing and feel better once again.

Don't. If she left you to go to Korea then obviously she doesn't want to see you.

If she left you then she wants to remain gone.

I'd let her go and move on.

Why would you want to find her & unless to file for divorce

Don't go searching for her, clearly she doesn't love you, she would have taken you, or stayed with you if she loved you, and if she loved you even a little she wouldn't be staying with another man, but she is, find someone better.

Korean consulate but if she was leaving somewhere else to go back to Korea she really doesn't want to be with you let it go

That sucks, but you have to move on. Get the divorce!

If you were married in Korea, you would be listed on her family registry. You could give a call to a district office that her last address was at and request an updated version of it. Just claim it is for your visa. If you have an F2 visa in Korea, you could do that. If not, the only way is to go over there yourself and figure it out. It's not worth it as far as I'm concerned, and MY wife is Korean. If she did that, lol I'd basically laugh.

i'd say move on.

Cash in your savings and head to SE Asia. Spend your time sitting on the beach and, if need be, get a job teaching EFL. Drop out of the rat race. Nothing like SE Asia to make a man forget about lost love!

Don't. Get a lawyer instead.
