Secondary sponsors and notarization

Hi, and thank you for responding to my question. I am sponsoring my husband for his greencard. At the moment we both live in Israel, so we asked my parents to be his secondary sponsors. With the application, we sent my passport adn other information, and also copies of my parents passports etc. My question is, for the actual meeting at the consulate, we will only have copies of their passport and ID's and paperwork, and all of my originals. From what we read on this forum, having notarized copies of all forms that have been translated is not necessary. However, do we need to notarize my parents passports etc. and bring notarized copies of their stuff? Thank you very much!!!!
