Yes, NYU does not require tests (beside TOEFL/IELTS) from internationals, not just Tisch.
But since Tisch is almost impossible to get into, especially for an international who currently doesn’t have a portfolio and will need financial aid, OP as an international who will need a full tuition scholarship would also need to apply to many schools requiring the SAT; fortunately the Korean school system trains kids for this type of tests so Korean students tend to do very well on standardized tests.
