I received a Temp evidence (I94) with stamp on it
Not sure about your office, but here is my story..
my GC was approved recently and my local office faxed my attorney that thay have approved our cases and sent a written notice. However, since we did not receive the notice for about 2 weeks, we went to our local offices to get some kind of written evidence. The IIO at the office asked for passport
size photo, glued it on I-94 card, filled in all the details and stamped it,that mentions this is temporary evidence of lawful permanant residence.
She mentioned nowadays, they avoid giving these temp cards, unless the applicant has some need like travel abroad, etc etc
