Lost Green Card Found

[immihelp]

I have found a lost green card at the place where I live and work. I know that this person desperately needs this card and identification. How can I get this back to the US Dept. of Immigration and Naturalization? Or even back to this person?
Thank You

It would be best if you could kindly locate the person in your company and give it back.

You could ask the receptionist or HR to find out how to contact the person
