Is I-551 same as Green Card?

I-551 Form was called a Green Card because it was green in hue. The card grants an immigrant permanent resident status for up to 10 years at a time. It also has the potential to be renewed before it expires.

If the document is a permanent resident card, Form I-551 is the form number for a Green Card. It is proof of a foreign national’s immigration status to live and work permanently in the United States. Note that “I-551” is printed in the upper left corner of the backside of your Green Card.

On the other hand, Form I-551 may be printed on documents other than the green card. Temporary proof of permanent residency can be on an immigrant visa or on a passport, for an immigrant who has lost a Green Card, for example.

Form i-551 for New Immigrants

If you have been granted permanent residence at a U.S. embassy, a consular officer will place an immigrant visa inside your passport before you depart for the U.S. When a new immigrant first enters the United States, a Customs and Border Protection (CBP) officer will stamp the passport with an admission stamp that indicates you have permanent resident status.

The stamp will also include the date you entered the U.S. Your foreign passport with the MRIV is evidence of permanent residence status for one year from the date of admission.
