"So the sheriff made the decision to go ahead and focus on Multnomah County resident applications, try and reduce that backlog, and then we'll re-open the process for Washington State residents who have business here in Oregon."
Oregon is a little different than most states in that while resident CCW licenses are required by law (shall issue) if the person meets the requirements, non-resident CCW licenses (contiguous states only) are completely discretionary (may issue). This means that the it can (and does) vary from county to county. I know of at least one county that simply does not issue to non-Oregon residents.
It would appear that the Multnomah County is currently inundated by applications. We can assume that since they get a lot of WA applications because of Portland. They state that they will reopen the applications at least from WA in the future. What about the other states, I wonder?
Is it coincidental to the fact that Multinomah County just passed some interesting new firearm restrictions? New restrictions include the open carrying of a firearm while hiking and making it illegal to have a loaded magazine in "public" even if you don't have a firearm! See source: Oregonian
I guess we will find out what happens in the future.
