I just spoke with IIO by name Charles. I asked whether I can stamp my passport using the courtesy copy. He said they SHOULD allow stamping. His exact words are \'I don\'t see any reason why they won\'t. Its your case and it has been approved and you got the letter. It doesn\'t matter whether it is Original or Courtesy.\' And also I asked him is there any local number for the INS Newark District office. He said NO. And wished me luck for stamping tomorrow. Look like a good guy. Anyway I will go tomorrow with the courtesy copies and post my stamping experience. Hope this info is useful for all.
