I seem to recall getting the paperwork we provided back with the actual passports.   However take that with a grain of salt as this was like 8 years ago and I get confused about little details and Nikki didn't remember either way.  I know I did get them back though as I would remember going through another round of the song and dance with the state department to get a copy of my birth certificate since I was navy born in Japan.  I envy people who can just go to their birthplace and get the dang thing.  The state department makes it such a production.  

Hi Briannah,

Thanks for your reply. In my case I think they have kept my documents because I also applied for a pass-book which has not arrived yet and in a recent email it was indicated I may have up to three packages.

On a side note, I really don't need the pass-book but thought, what the heck, get one  

I agree!   There is something neat about the little blue( it was blue when I got mine) books.  I have no stamps as I'd never gone anywhere that required Visas.  I basically only have it because we go to Canada and the Carribbean often and they tightened the laws.   We HAD to have it for a cruise to Alaska because it stopped in Canada for literally four hours.  Lol

Update, came home today and the pass-book and documents arrived woohoo.
