USCIS extends Green Card validity. 
Beginning Sept 26, USCIS is automatically extending the validity of Permanent Resident Cards (also known as Green Cards) to 24 months for lawful permanent residents who file Form I-90,
Application to Replace Permanent Resident Card.
The language in Form I-90 receipt notice has been updated to provide notice of the 24-month validity extension.
The updated receipt notices with the new extension can be presented with an expired Green Card as evidence of continued status.
The agency anticipates that this extension will help applicants,
Who experience longer processing times because they will receive proof of lawful permanent resident status as they await their renewed Green Cards.
