韩国过境签证怎么办理？
韩国济州岛入境免签，所以不需要过境签证。 另外，目前只有中国、日本和马来西亚的可以办韩国的过境签证（C3）。 C3是短期过境签证，可以允许你在24小时之内离境去别的国家而不用再去大使馆或领事馆重新申请签证。
但要注意的是，它只适用于从第三国到韩国再去第三国的转机旅客。如果你的最终目的是去韩国而不是转机，那么你就不能申请这个签证了。 如果你的护照上已经有韩国的签证（任何种类的都可以）就可以在机场申请一个24小时的落地签证，只需交纳95美金。 但如果你只是在香港或澳门转机时间不足12个小时的话就不能申请了哦！而且必须要在你出海关的时候才申请的。 申请手续并不复杂，只要带着护照原件和一张两寸白底的证件照就可以了。不过最好先填好了申请表和准备足够的现金，因为有些机场不提供填写服务的喔~
韩国个人旅游签证有分为个人C-A-T-S和团队L-A-T两种类型： 首先说一下签证的种类：
A-Type Visa： is issued for the purpose of visiting Korea by a business visitor. It can also be used to transit through South Korean Airport. For this type it's required that you have at least one month validity remaining on your passport and two blank pages are available;
B-type visa：is an entry visa that allows multiple entries into ROK with a maximum stay of three months， which may not exceed six months in total. This visa should only be given as a tourist (or other leisure purposes) or visit family. You must apply from outside ROK but if traveling via South Korea’s international airports you will usually be eligible for a transit visa upon arrival(this depends on individual circumstances);
C-Type VISA ：issued for visits of up to a maximum period of five years， single or multiple entries permitted. The application process varies according to the nationality of applicant， however all applicants must undergo police checks before their visas are processed. Please note： If applying using your own passport we cannot issue more than three year validities. This is because some countries have restrictions within their national law against long term travel. We advise those who fall under these category’s to choose another type of visa;
D-Type Visas：This visa permits foreign residents currently living in North Korea to enter South Korea without prior approval．They do have to present themselves at one of several designated border crossings when they wish to return. This special visa does not allow holders to leave South Korea， however；
E- Type Visa：this e-visa system was designed primarily for Chinese nationals wishing to travel
