Thank you for the reply. Can I use the expired green card travel

Is there another paper or another way I can use to travel with my expired green card? Or Do I need to renew my green card while I am waiting for USCIS processing my naturalization? From what I learned, it takes 8-10 months for renewing the green card, but before the new card comes in I am still not able to travel. What is the point to renew it?
