i wonder if someone has been in the same situations. On 5th of sept i filed ar-11 online change of address. On 16th of sept i called to confirm the address,they said they had it updated.On 5th of october my AP turns undeliverable for 2nd time-i call and confirm the address for 3rd time. Today my AP turned undeliverable again.I took infopass appointment 2ice-they really have my address and my name has been on the mailbox since sept 5th. i dont know what to do and why it happens like that. Meanwhile i received two letter from Uscis already on this address. Only my AP turnes undeliverable. I dont get that.
