Holders of a green card without an expiration date had to renew their green card within 120 days after the Final Rule was published. Check to see if the card is a Conditional Residence Green Card. If so, the card expires two years after the date of issuance. Check the issuance date. If the green card is a Permanent Resident Card, then the expiration date is ten years after the date the card is issued, or within six months of the ten-year date.
