The cost to renew a green card is $450 as of April 2014, according to the U.S. State Department. The cost includes a fee of $350 for filing the appropriate form and a cost of $85 for services such as fingerprinting and taking a picture.
A green card, which is the common term for a Permanent Resident Card, expires every 10 years. The holder of the card must apply for renewal to the U.S Citizenship and Immigration Services, a division of the State Department. A green card holder's status as a legal resident, however, is permanent once granted and never expires unless the holder violates certain laws and regulations.
