You may file Form I-90 to renew your green card up to six months before the expiration date. Filing early helps avoid gaps in documentation, especially if you need proof of status for employment or travel. Once filed, you will receive a receipt notice that may extend your status while the renewal is pending. Processing times vary, so submitting the application in advance is generally recommended to prevent complications.

Although permanent resident status does not expire with the card itself, the physical card must be valid for identification and employment verification purposes. Filing for renewal before expiration ensures you maintain updated proof of status. Keep copies of your receipt notice, as it may serve as temporary evidence of lawful permanent residence while your application is being processed.
