BTW, when looking at the 2017 class profile, I was surprised to see that UW has way more OOS applicants than in-state applicants:
WA Residents
12,394 applied
7,335 admitted, 59.2%
4,443 enrolled
Nonresidents (U.S. + International)
32,487 applied
13,498 admitted, 41.5%
2,331 enrolled
Wow, if all the accepted OOS students come, they will totally outnumber the in-state students.
