money laundering, human rights violation, life threat, student exploitation and research and academic crime

Hello. I was a student of phD in South Korea and faced some illegal actions being carried out by the group I was working with. It included money laundering, human rights violation, life threat, student exploitation and research and academic crime. I can provide details. I felt life insecurity and had to come back to Pakistan over night. I have not informed anyone in institute and they are on hold. I want to take legal actions against them for what they are doing and what they did to me. Please help me as I want to ensure the integrity of Pakistani passport, as many people told me to just put up with all this because I had a green passport.
