U.S. Citizenship and Immigration Services has introduced several new features to its website and online case status system. Among the new features is an online e-Request tool that allows individuals who have filed a Form I-90 application to replace a permanent residence card or an N-400 application for naturalization to send an inquiry if the case has been pending for longer than the agencys stated processing times or, in the case of an I-90 application, the applicant has not received an appointment for biometrics.
