How to apply for visa extension after studying in Korea?

First of all, visa extension needs to be justified, such as work, marriage, study and so on.

If you are an engineering graduate, you can extend your visa for half a year on the grounds of finding a job. If you are a graduate, you can extend your visa for half a year on the grounds of looking for a job, regardless of your literature, science, engineering and sports. However, the above extension requires a guarantor, usually a professor from the graduate school to write a letter of recommendation to ensure that you find a job here.

In addition, you can also choose language training, but the visa will be changed to D4 and the visa will be extended for half a year. You also need a professor to write a letter of recommendation to ensure that you are studying languages, not working illegally or doing anything else.
