I’m just curious if they do, like some other UCs such as Santa Barbara.
What do you mean by late application. As far as I know, the system shuts down after deadline so you cant even submit , so there is no such thing as a late application.
Some of the UC’s (obviously not sure on most of them) offer an option to appeal for a late application. If they accept your appeal, they re-open the application system.
Here’s what UCSB’s website says, "To apply for admission after a filing period has ended or for a UCSB term that will be closed to new applicants, you must submit a written appeal. Consideration for appeals is based on your overall application and extenuating circumstances. "
