USC确认ad之后可以改项目吗

申请了usc两个学院的两个项目，但是目前只有一个给了ad，另一个还在等待中。已经录取的项目要4.16之前确认，想问如果确认了之后另外一个项目也录取了，我可以更换项目吗？

ps：usc grad school官网没有明确提示，只有以下说明：
If you wish to be considered for a different program in a different school at USC, you will need to apply directly to that program.  

To change programs within your school, you will need to complete your first semester in the program to which you have been admitted. You may then request a transfer to another program, using the Change of Major form. Your request will be reviewed by the department to which you are requesting transfer. Requests for a change of program are not automatically approved and the decision is at the discretion of the department.

2) Yes, you can certify for the program to which you have been admitted and then change it if you are admitted to another program in which you have greater interest


参考以上工学院小蜜给我的回复，是否普遍适用未知。但我认为大概率可以。

好的，非常感谢！！！
我也再咨询下学校。

update：
grad school回复说可以的。

ps：
You may change your program if you are admitted by the second school.
