Oooo, I'll be using that office in June when I do my biometrics, I'm like 45 minutes outside of Portland. It's good to know that they're reasonably quick at least, as long as they do it right 
The first time I went there I drove right past the office and promptly got confused and lost in Downtown Portland what with all the one ways

This time I printed out a Google Street view of the building so I could visually see it and remember this time not to fly right on by. The office is so nondescript, you wouldn't know they are doing fingerprints etc.. in there. There is literally a piece of paper stuck in the window telling what the office is all about, the door has a huge 721 over it, other than that you would drive right on by which I did.
