About 2 months ago, I knew from the customer services by calling USCIS that my application of I-751 was approved. It was processed in California. But as my district service center is Vermont, any notice should be sent by Vermont. Unforturnately, Vermont system doesn't have my updated address. So, the Customer service put a request to update address and ask them send me the approval letter. I checked back once and they still said the case is approved but Vermont hasn't responded yet. Since it's more than 30 days, I called back one more time and was surprised to know that they are not sure whether the application is approved or not although the system shows the status as approved, no written notice was mailed out yet. They shouldn't have confirmed with me about the status.
Does anyone encounter similar situation? How does their system work? I'm very confused about the case status now. Also, this is a over process time case. I can't check it online as it won't automatically pop up. Is that why it is so messed up?
