interview for my citizenship without my greencard

[immihelp]

Hello,

I sent my greencard back to USCIS due to an error on their part. They wrote my name wrong. My problem is that i have an interview for my citizenship and they require that i have my greencard. What do i do since USCIS have not sent it to me yet?

Talk to USCIS about it to see what they can do.
