An I-551 stamp is temporary evidence of lawful permanent residence. It is issued in the passport upon arrival in the US, and serves as proof that the immigrant has permanent resident status while the actual green card is being generated.
When a new immigrant first enters the U.S., U.S. Customs and Border Protection (CBP) will stamp the passport with an admission stamp that indicates the date they first entered the U.S, and the date it is valid until.
USCIS will typically issue the I-551 stamp with a validity period of six to twelve months, and usually has the following text on it: “UPON ENDORSEMENT SERVES AS TEMPORARY I-551 EVIDENCING PERMANENT RESIDENCE FOR 1 YEAR.”
