I'm replying to someone who wants to change her situation while being in South Korea on D2 visa.

Tutoring is generally prohibited under that visa, while it can be possible to work either 20 or 30 hours per week depending on whether you are in an undergraduate or graduate program.

Please refer to this link and if you have doubts, please check with Korean Immigration. 

I'm an American and until Donald Trump became president, I was inclined to say that labor laws and working conditions were more protective in the USA than in South Korea.  Most foreign workers are in South Korea are under some sort of E visa, E1 and E2 for teachers and the E7 visa covers almost everything else.  Because D2 visas are primarily student visas, issues including the black list and saying anything negative about your employer probably do not apply, but keep in mind that Korean defamation laws are draconian, so if you leave a Korean employer, it is wise not to say anything negative, even if your comments are completely true. 

It is very easy to run into difficulties with the Korean authorities, so if you have doubts, it is safest to check with them before taking almost any work.  You should also consider how long you intend to remain in South Korea.  Most foreigners who intend to remain in Korea long term eventually consider whether they are eligible for F2, F4, F5, or F6 status.
