Yes. Immigration will not give you your certificate of naturalization until you give them your old green card. You can file an I-90 for a duplicate and when you get it, give it to them. The other alternative is to file a police report and/or convince them that you have really lost it. However, it has been my experience that they will not give youyour naturalization certificate until you give them your old green card.
With all due respect to Mr. Mayer Kantor, I respectfully disagree. I notice that the poster is from Chicago. I am an immigration attorney in Chicago and our local office does not deny naturalization applications for this reason. I have had clients in this situation in the past, and I made an INFOPASS appointment for them to meet with an information officer before their naturalization interview. We brought their N-400 receipt and unexpired passport and asked that an I-551 stamp be placed in their passport to use as evidence of their permanent resident status until their naturalization case was approved.
