Legal Question in Immigration Law in New York

Re: Expired Green Card

Even if you are allowed to board a domestic flight, you should apply for a replacement card as soon as you can to be able to prove your legal status without potential hassle if stopped by law enforcement and in other situations.

Re: Expired Green Card

You are still a lawful permanent resident even if your card has expired. However, I don't believe you can board a plane and use that as one of your forms of photo ID's. You would need to call the airlines to find out what ID documents you need for boarding the plane. Probably an unexpired drivers license and passport will be OK.
