You should definitely email the admins about the WA college thing. I think I briefly heard an admin during my interview that UW only considers which university/high school you attended.
Update: Just asked my classmate who is a resident outside of the WA and the WICHE states. Did their undergrad at UW and is in our class. So
@wjc, possibly next cycle?
