Expired green card

Hi all,

My husband and I went to our TSA pre check appointments with Idemia this weekend. Mine went fine without any problems, but he was turned away because he is a green card holder. His conditional green card expired, we filed for removal of conditionals before the deadline, but due to the backlog, he was issued an extension, which is essentially a letter from USCIS that says his conditional green card is extended while they process his application. We were able to travel last year with his expired green card + extension letter.

I’m here to ask if anyone else is in the same boat, and if you were able to get processed at your appointment? I read some things online where they made some phone calls and just moved the expiration date per the extension, but the guy at our appointment just flat out told us that he can’t apply without a physical unexpired card. Any help would be appreciated. Thanks!
