Extended data

There are three forms of admission to American universities, namely ED(EarlyDecision binding), EA (EarlyAction Unbound Early Admission) and RD(RegularDecision Regular Admission).

The application time and application object of ED and EA are similar, but there are still great differences. Once students who take the ED route are admitted to a school, they cannot choose other schools. In other words, you can only apply for one school that offers ED admission. If you are admitted, you must choose it. Even if other schools offer you better conditions, you have no right to change your decision.

Violation of ED rules will lead all American universities to reject students, because in the school's view, such students' integrity is questionable. However, if you are not accepted, you can still apply for RD normally.
