On August 22, 2007, USCIS published a proposed regulation that, when implemented, would require lawful permanent residents to replace permanent resident cards (Form I-551) with no expiration date. This proposed rule in no way affects the current validity of these permanent resident cards. Permanent residents who possess these cards may continue to use them as proof of permanent residency when traveling, when seeking employment, and at any time such proof is required.
The final rule, once published, will explain the process to replace these ‘green cards’. Persons who hold these permanent resident cards with no expiration date may replace their cards now, but there is currently no requirement to do so.
