I endorsed my license from California to Oregon and it seemed OR process was very quick especially with everything being online and the ability to check the status of each requirement online.
The longest waiting period on the part of OSBN was the background check that took about a week and a half. But it was CA who dragged their feet the longest and took 6 weeks to verify my license (even tho they cashed the check after just one week) and they do not take inquries until its been over 8 weeks
. So in total it was about a 2 month process for endorsement. The CA board website states to expect 6-8wks for processing on their side alone so it's not just the OSBN you're waiting on, check your current state AND original state of licensure boards for wait times as well. Since OR doesn't do livescan there's also the possiblity of having to repeat your fingerprints if they are rejected so I would recommend starting the process ASAP and give yourself some wiggle room, although it would be awesome if it worked out under a month!
Funny enough OR no longer issues actual license cards so I was actually licensed 5 days before I even noticed according to their website but since I didn't sign up for email notifications I wasn't even aware. So keep an eye on the website!
