SM is very strict about whether your asian or not, and it isn't a very good company especially because of the lawsuit and things that happened with TVXQ. But you should still try! Also, Cube entertainment is debuting a group with a caucasian boy named Kyle Moffat in it. It's called Esquire, so if your willing to try other companies, you should try Cube! It's owned by JYP, but has its own website/auditions and also holds global auditions like SM does. I'm a caucasian girl too, and I plan on auditioning for both SM and Cube :) Good Luck!
