Will I lose my permanent resident status if I do not renew my Green Card?
No, you will not lose your permanent resident status if you do not renew your Green Card – your permanent resident status will not expire or change if you do not complete Green Card renewal. However, you are required by law to carry evidence of your status / registration (e.g. a valid, unexpired Green Card or the temporary proof of status you receive at the time of filing to renew your Green Card.)
