Yeah, I hope so.
For all the reading i've done (and i'm no expert by a long shot), they often give you the AP paperwork like the different color pieces of paper at the interview.
I'm thinking seeing i didn't get anything, and he said approved it's just waiting...
I've had a few friends go through the E-3 process though and they have gotten their passports back in like 2-4 days. That's why I'm thinking something they're looking into... not sure what it could be. I just wish if there was something, they'd have reached out already so I could tell that what they need and get it sorted (Interview was 13th March, so 2 weeks now)
