A PERMANENT RESIDENT CARD (USCIS FORM I-551)

is proof of your permanent resident status in the United States. It also serves as a valid identification document and proof that you are eligible to live and work in the United States. Although some
Permanent Resident Cards, commonly known as Green Cards, contain no expiration date, most are valid for 10 years. If you have been granted conditional permanent resident status, the card is valid
for 2 years.It is important to keep your card up-to-date. Without a valid card, it may be difficult for you to prove that you are a permanent resident, and this could also affect your ability to travel or to prove your eligibility to work in the United States.

WHEN DO I NEED TO RENEW MY PERMANENT RESIDENT CARD?

You should renew your Permanent Resident Card if you were issued a card valid for 10 years that has either expired or will expire within the next 6 month
