Sorry abt the loss
Even we tried in Atlanta for emergency AP in Sep-03 when my wife brother had severe accident back india, they refused to give saying that my original 485 address is houston (yes my 485 address is houston), then she traveled to Houston to get the emergency AP and she got it. They did not grant me AP, because the patient is not my immidiate brother. They say emergeny AP is only for parents/kids/brother/sister, no in-laws.
