U.S. Citizenship and Immigration Services announced a redesign to the Permanent Resident Card (also known as a Green Card) and the Employment Authorization Document (EAD) as part of the Next Generation Secure Identification Document Project. USCIS will begin issuing the new cards on May 1, 2017.
In the announcement, USCIS states the redesigns use enhanced graphics and fraud-resistant security features to create cards that are highly secure and more tamper-resistant than the ones currently in use. Further, the new card designs demonstrate USCIS’ commitment to continue taking a proactive approach against the threat of document tampering and fraud. They are also part of an ongoing effort between USCIS, U.S. Customs and Border Protection, and U.S. Immigration and Customs Enforcement to enhance document security and deter counterfeiting and fraud.
