For those of you who have not seen the current I-551 stamp (also referred to as the“ADIT Stamp”), it is below. It has stars in the four corners; on the left margin the vertical letters, USDHS, and on the right margin the vertical letters, USCIS. An “ADIT” Stamp is added to a passport or an Arrival-Departure Record (I-94) as temporary proof of residence. To alleviate inconvenience to our customers, USCIS continues to aggressively pursue technological improvements to allow the prompt issuing of permanent alien resident cards (“green-cards”) without the need to issue these temporary stamps.
