I'll get you onto the trail of application...or at least very close to it. We get quite a number of Washington residents coming down to train with us and most if not all end up with Oregon Concealed Handgun Licenses.
Some basic steps to follow to increase your odds...
1. In Oregon you apply through the county. We have 36 counties in Oregon and each county must follow the statues but they have some discretion on the application process and procedures. So there are in essence 36 different ways to apply. Next,
2. Familarize yourself with the Oregon Revisied Status - particularly 166.291 which can be found on this link -

3. I'd start immedately Monday AM calling the Sheriff's Office (SO) Civil Division in the bordering counties next to WA (but staying away from PDX metro counties) and asking them, assuming you have met all the requirements, would they allow you as a WA resident to apply in their county.
4. Obtain the training and neccessary declairation required to submit to the Sheriff's Office (SO).
5. Apply in one of the bordering counties SO and generally avoid large metro counties....step number 1 will determine where to apply.
6. Apply per the county requirements and be prepared to wait no longer than 45 days by statue requirements to get a "yep or a nope."
