Performing Arts School

I'm A 14 Yr Old From The Philippines And My Dream Is To Study Drama In A Performing Arts School Abroad. I've Always Wanted To Study In Juilliard But Any Performing Arts School Is Fine. I Want To Prepare Myself Early For A School Like This. What Kind Of Skills Do I Need? Do I Need To Learn Dance Like Ballet Or Jazz? Do I Need To Learn How To Sing? Get Into An Acting Workshop?

Any Tips For An Aspiring Performing-arts-school Student?
