Question about online audition in SM ent, JYP, CUBE, YG, LOEN, TS Ent, NH media, etc. I wanna go to kore!!?

Make sure you have a parent ready to go to Korea with you. Unless you are extra ordinarily talented, it is unlikely that you would be selected. Video auditions should be professionally produced with proper lighting and sound. If your parents are not in on this, forget it, they wouldn't let you go anyway.
