A Permanent Resident Card (USCIS Form I-551)
is proof of your permanent resident status in the united dtates. 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. an article on this manner- https://thegreencard4u.com/dv-lottery/
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.for more check: https://www.dvlottery.state.gov/

When do I need to renew my 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 months. we recommend to read this.
If your Card is valid for only 2 years, you are
a conditional resident. You will need to file a petition to remove the
conditions of your before the card expires. You may file
this petition 90 days before your conditional green card expires.
