其实这个4.15协议现在已经越来越多的大学没有在遵守了，因为随着美国大学申请者逐年的增多，录取委员会的评审任务越来越繁重，导致评审时间延长，越来越多的学校都不能在4.15之前给出最终的decision，所以学生也没有办法在4.15之前给学校回复。至于究竟有哪些学校，现在已经不好给出确切答案了，只有看学校的邮件通知或者录取信里面的说明到底什么时间之前给出回复。

1999年，美国多家大学联合制定并实施针对外国研究生的“4·15协议”，主要内容为：申请赴美留学、已拿到多个带offer（有关财政资助）的学校录取通知书的研究生，必须在4月15日前决定一所你要去的学校，否则，所有录取通知书将都被视作无效。学校名单：
