The Grant County, OR Sheriff is very amicable to granting OR CHLs to Washington residents. Generally one has to travel to the county (an eight-hour drive from Tacoma) to turn in the application and fees and only on Wednesdays. Sheriff Palmer will be visiting Vancouver, WA sometime prior to Christmas and offered to meet me there for application turn in, photos, and electronic fingerprints. He also mentioned that it would be great if there were more than the 8-10 that showed up last time he did this. After sending emails back and forth I've volunteered to pass the date (to be determined) to those interested. I am an NRA Instructor and can even provide a block of training including the handgun safety portion required by OR law in order to make application though if one has documentation of training they would not need it from me.
