It's appropriate to say you are in the process of obtaining a WA license by reciprocity.
Start now, as these things sometimes take a lot longer than you think. Eight weeks is not uncommon; the fastest one I ever got was 10 days (yay, Nebraska!) but California took months. Different states have different requirements for this, too-- you may need to have (and pay for yourself) a CORI check, fingerprints, specific CE in one subject or another (NY requires an online course on abuse), etc. Everyone wants a certified copy of your school transcript (fee). Some want Nursys verification of your current licensure (another fee). Good luck!
