Update: It has been little over 1 month. He already found a job as an english teacher and made a girlfriend. Met all the cousins and seem like he is doing fine. He got his paperwork straight and listed for korean military. In the meantime, he is saving money and enjoying life. Perhaps leaving US is not bad after all.
