Oh yeah, I'm a permanent resident now.

I got the stamp on July 11. It took me half a day of waiting in lines to get the stamp.

I showed up at the INS office at 7:30. There was already a long line. The office didn't open till 9:30. The line was enormous by that point. I didn't get in the building till about 10:00. At that point, I got my number and sat down in a waiting room. My number wasn't called till 1:30pm. It took the guy all of 3 minutes to stamp my passport and process my paperwork.
