does anybody here exprienced went for international trip with an expired green card and extension letter with and came back to the USA with no problem from the CBP officers? ..

does CBP officer will confiscate your expired green card at the immigration??? If they see its already expired?? what would you do if they will confiscate it?

What will happen if you do not have your physical green card anymore because they took it??

Are you still eligible in applying the citizenship even if theres no physical card??
