A friend wants to know, what does this mean?
You must have an application pending for at least 150 days before you can apply for a work permit, which is called an Employment Authorization Document (EAD). The number of days your case is pending is determined by the EAD Clock. The EAD Clock is calculated based on the total time your case has been pending for adjudication, which can be with USCIS, the Executive Office for Immigration Review (EOIR), or both. The EAD Clock does not include delays you caused or requested in the processing of your case before either USCIS or EOIR, which stop the EAD clock.Your case has been pending with USCIS for 664 days, not including delays, and the USCIS portion of the EAD Clock is currently running. If your case is no longer pending with USCIS, the time noted here may not be complete. For more information, please see the USCIS website.
