I am a local employee of a company that employs foreign workers. A foreign worker (E-9) in our company wants to invite his wife from Nepal to Korea. What procedures and documents does he needs to prepare to obtain a visa? I've been working together for years, and I've watched him, and he's a sincere and a diligent person. He has been unable to go to Nepal for several years because of work, and He miss his family very much. What could I do for him?
