From USCIS.gov via email:
On Sept. 26, 2022, USCIS automatically extended 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 (Green Card).
USCIS is in the process of sending out amended receipt notices for individuals with a pending Form I-90. You can present an amended receipt notice with an expired Green Card as evidence of continued status. By presenting your amended receipt notice with your expired Green Card, you remain authorized to work and travel for 24 months from the expiration date on the front of your expired Green Card.
If you are in urgent need of evidence of status while you wait for your amended receipt notice or your replacement Green Card, or if you need another in-person service, you may call the USCIS Contact Center to request an appointment. We encourage you to wait for your amended receipt notice instead of scheduling an appointment that you may not need.
