Mr.KALLISTAMIST000, you have to apply for a China visa through one of the travel agencies designated by China embassy/consulate in South Korea, now the important requirements is the Alien Registration Card valid for at least for 6 months rather than the flight ticket. If the flight tickets are required, you can book it through the travel agencies, however, I don't think you can get a China visa in South Korea because you don't have the alien registration card. Now aliens other than Korean can't get a China visa from China embassy in Seoul if they don't have the alien registration card valid for 6 months, but they still have a chance to get it from the China consulate in Busan, but you even don't have the alien registration card valid for less than 6 months. You can't get the visa from the China consulate in Busan, either.
