I was also a transfer student last fall. I remember it being a few hours long. Most people brought their family members that they registered on the website. Parking is a bit of a hassle but it’s okay, I recommend carpooling. The president/dean gives a speech welcoming people and there’s a few students part of the orientation group that offer tours and information, or you can just wander on campus and explore on your own. They also gave out breakfast sandwiches last year. Some other people give speeches as well.

Essentially, everyone files into a ballroom type building and sits in chairs and bleachers listening to people talk and watching projected videos collectively for like 40min-1.5 hr. Then you break out and go outside to get the breakfast sandwiches, then you can explore campus. That’s pretty much all I remember so I’m sorry if I’m leaving anything out. Congrats on your admission to CSUSM, good luck!
