I have sent an I-130 withdrawal letter to the Phx and Connecticut offices about a month ago. They were both notarized and included the reason and case number. The one sent to Connecticut came back saying that they did not find the case. However, the one sent to PHX did not come back and I have not heard if back if the withdrawal happened. When I look at the case online, it still says in decision. Will I get notice if it was withdrawn? If not, how can I check if it happened?
