Lost Item No.: 1083503 - John F Kennedy International Airport, New York, US

Hi my name is Gijang Kim. I have lost my Greencard at JFK. My flight was Korean Airline KE081 which arrived to JFK at 10:00am EST on January 20th, 2018. Right after I passed the Customs, I put my greencard inside my passport and then I put my passport inside my jacket pocket. However everything except the Greencard was still there when I got back home. I am assuming that it must have slipped while I was putting it inside my pocket between the customs and the luggage pickup conveyor belt at Terminal 1.
