Got courtesy copies by mail yesterday (11/13/01). Reached INS at 6.30 am and came out 11 am. The actual stamping process took only 5 minutes. went with courtesy copies only. There were around 70 people before me at 6.30!!! It was damn cold.. chilling... They let us to go in only at 7.30. I suggest wear warm apparels, even you need gloves and head bands.. Everybody there were cursing the cold.. Other than that every thing went ok, they called my number at 10.55, and stamping was done in 5 minutes for me, wife and son
