LOL MorganSF - I did remember to write my name on the back (thankfully). I also didn't know it could be stapled; maybe you got a 'checker' with common sense.
It looks like the May applications are starting to move now, so June can't be far behind! Then July.... I checked statistics for the past couple of years re: total applications, and it's been over 200K per year; don't know what quarter typically have the largest number, but I figured the monthly average to be around 17,500. That's a LOT of paperwork to sift through!
Someone on immigrationboards.com also pointed out that if they slow up the naturalization processing, it also delays some future passport applications....yours, mine.....
Patience is NOT one of my virtues, but trying to stay positive.
