U.S. Citizenship and Immigration Services (USCIS) announced at the end of May that applicants may experience a delay of up to eight weeks in the delivery of their permanent resident cards due to an upgrade of USCIS' card production equipment. Temporary evidence of permanent residence in the form of an I-551 stamp will be provided to applicants who are approved for permanent residence at the time of their interview. Applicants must bring a passport to the appointment in order to receive the I-551 stamp. If the applicant does not have a passport, a passport style photo and government issued photo identification are required to receive temporary evidence of permanent residence. Applicants whose approval is granted after the interview or by a Service Center or the National Benefit Center, can receive temporary evidence of permanent residence at an INFOPASS appointment.
