International Transfer Orientation?

I am an incoming FRESHMAN international student. I am graduating from a high school in Minnesota this sunday.
Two days ago, I got an email titled “International Transfer Orientation” and it says I have to attend an orientation on either 6/9, 7/7, or 8/4. The thing is I wont be in US for any of these days. I checked iTerp and apparently, this is only for transfer students.
I am pretty sure this is sent by a mistake, but the email clearly says this is part of my orientation and does not say if it is for transfer student only or not. So if I really have to attend this, I have to change my flight (I was planning to go home on Monday, 6/5) and will stay in US to attend the orientation.

Does anybody have the same issue or any thought on this?
Thank you in advance.
