If your green card expires, it does not mean you lose your permanent resident status, but it does mean you no longer have a valid proof of that status. An expired green card can cause problems with employment verification, reentry into the United States after travel, renewing a driver’s license, or proving lawful status when needed. To maintain valid documentation, you must file Form I-90 (Application to Replace Permanent Resident Card) to renew your green card, which is usually valid for 10 years. If you are a conditional permanent resident (for example, through marriage or investment), your card is valid for 2 years, and you must file to remove the conditions (Form I-751 or I-829) instead of just renewing. It’s important to take action before the card expires to avoid disruptions in work, travel, or status documentation.
