Accept a currently valid Form I-551 Stamp.
               When the alien does not have a machine readable immigrant visa, per RM 10211.025C.2 in this section, DHS places a Temporary Form I-551 stamp in the foreign passport
                  as evidence of immigration status when the alien is admitted to the US as an LPR.
                  The LPR uses the Temporary Form I-551 until the permanent Form I-551 card is received.
                  The stamp may be placed in the alien’s foreign passport or on a Form I-94, Arrival
                  Departure record.
               
               DHS USCIS will continue to issue the Temporary Form I-551/ADIT stamp when processing
                  certain immigrant benefits (i.e., as temporary evidence of LPR status, until a replacement
                  Form I-551 is issued) and in adjustment of status situations.
               
               When an alien previously admitted to the U.S. applies for a replacement Form I-551
                  or adjusts to LPR status, DHS places a Temporary Form I-551 stamp in the foreign passport.
                  When the alien does not have a foreign passport, DHS places the Temporary Form I-551
                  stamp, a photo of the alien, and DHS seal on Form I-94.
               
               The Temporary Form I-551 stamp, which was printed in red through June 30, 2014, is
                  now printed in blue as of July 1, 2014. It reads:
               
               "Upon endorsement, serves as temporary I-551 evidencing permanent residency for one
                  year.
               
               Issue date     (date)   
               Officer     (name)   
               EMPLOYMENT AUTHORIZED
               Valid Until     (date)   "
               
               Each stamp is uniquely numbered with a five-digit identifier which can be found below
                  the “Valid Until” line. The officer also writes the A number on the stamp.
               
               If the Temporary Form I-551 has expired but the person has not yet received the Permanent
                  Resident Card, refer the applicant to DHS to extend the validity period of the Temporary
                  Form I-551 stamp.
               
               
                  
                  
                     
                     DHS may not specify an expiration date. In this case, the stamp is valid until the
                        alien receives a Form I-551.
