Effective May 11, 2010, USCIS will begin issuing a newly redesigned and more secure permanent resident card. The card is commonly known as a "green card" (and part of the redesign was to make it green in color).
The attached set of documents include information on the visual and security features of the card, who will receive the redesigned card, and examples of both the front and back of the card.
USCIS strongly encourages anyone who holds a permanent resident card without an expiration date to apply to replace their cards with the redesigned version. Existing permanent resident cards that bear an expiration date will remain valid until they expire. Holders of those cards will receive the redesigned version when seeking a renewal or replacement.
Employers should ensure that they are familiar with the new card as employees may be presenting this version as evidence of identity and employment authorization in relation to the Form I-9 and/or E-Verify.
