Will I lose my permanent resident status if I don’t renew my green card?

Ensure your Green Card is valid at all times.

The USCIS does not list “not renewing your green card” as one of the reasons you could lose your permanent resident status. But the USCIS does say that you are required to have a valid, unexpired green card with you at all times.
