Hey Dave – there’s a Cultural and Economic office downtown, you may wish to drop it off or call them if you’re so inclined: 600 University St #2020, Seattle, WA 98101 | Phone: (206) 441-4586
I hope the passport is reunited with the rightful owner. DaveB, you rock – that’s the way people should be. What a pain to lose a passport and how awesome to know that someone returned it.
