How do I audition for SM/JYP/YP?

aww well you should definitely pursue your dream of becoming famous in the kpop world!. I think the best way would be to submit an audition video to jyp and/or other agencies you're interested in. since it is very difficult for you to be present at one of their US/Canada auditions, sending in a video of yourself singing/dancing would be the most effective way for you to show them your talents. You have a high chance of being scouted since you are Asian and cutesy. Some kpop idols that are famous today did not really have a formal audition, but agencies were still able to see that they had amazing talent and charisma. Don't be discouraged by the fact that auditions aren't held in the UK. You are still very young and agencies prefer the young ones anyways nowadays. In terms of which agencies to apply to, it seems like jyp and yg are two of the more popular but still kinder agencies. You can always apply to Cube, Brave Sound, Pledis Ent., and all the others. :) Good luck with everything, and hope that helps!
