In the email I received from them it says:
We hope that you are enjoying the New Year! We are happy that you have chosen to apply to the University of Wisconsin, School of Veterinary Medicine for the Class of 2022.
This message is to provide you with an update on the progress of the admission cycle. Our admissions committee is in the process of selecting the class. We plan to notify you of the committee's decision by late February. All admission decision materials will be sent via postal mail on the same date. We wanted to share the progress of our review with everyone and to inform you that our Open House for invited applicants will be held on Friday, February 23, 2018 from 12:00-4:30 p.m. If you are invited to join the class of 2022 you will receive more information regarding this event in your acceptance materials.
