I am posting this on behalf of a friend, who is a green card holder but got their I-551 expired in March and needs to return to the US. The Embassy in Guatemala advised he must file a I-131a and pay the fee online, when he tries entering the Green Card # from his card, he keeps getting a message that says "Green Card # and DOB" do not match our records. He is entering the info exactly as it is in his green card, the number is under the USCIS #, and it does start with ZERO, and it has 9 digits. I tried helping him and I am getting the same message. Has anyone encounter this issue before? He tried calling the 800 number and it is impossible to talk to a live person. He called the embassy and was told to keep trying until it works. He has tried over 50 times and still gets the same message. Are looking at the wrong number maybe? Or is there a way to see if his number is valid. The green card is expired but his number should still be valid right?
