I had a fight record three years ago. Six months in prison. Passport should be fine. I want to work in Korea. Can I get a visa? Korea na

Yes, there is no criminal record to prove that this kind of thing will only be used when going out to cooperate with state-owned enterprises or large Chinese companies. Foreign-funded enterprises won't want it, and there is really no need to apply for a visa.

But it is not realistic to apply for a passport and visa in Korea. Usually, a lot of materials are needed. If you are majoring in Korean or Korean, it is much less difficult to apply, but it is impossible to apply for a passport.
