Q: My Green Card is expired. Have I lost my permanent residence status? What should I do?
A. Your status as a permanent resident does not change just because your card is expired. You remain a permanent resident unless your status is terminated by “final administrative order of exclusion, deportation, removal, or rescission (8 CFR § 1001.1(p)). Also, an expired permanent resident card only shows that a person’s card has expired. It does not show that the person’s work authorization has expired (8 CFR § 274a.12(a)(1)).
That said, I still usually recommend that my clients renew their green cards. An expired card could cause delays related to employment and travel, and it is generally prudent to maintain updated records. Depending on where you live in the US, and when your green card expired, it may be possible to proceed with Citizenship without first renewing your greencard, but you should check with an attorney before choosing this route.
Renewing your green card is done through USCIS. If you have lost your card, or your name has changed, these issues can also be taken care of at the time you apply for a new card.
