CONFIRMATION FROM USCIS

We received a receipt from USCIS in Memphis, Tennessee that they received our I600A and our filing fee. We hope to have our fingerprint appointment in about a month. We know that our homestudy was sent to them, but the social worker forgot to send it Fedex so that we would have a tracking number. ARGH!!! We have no way of knowing right now if USCIS has our homestudy or not. I am going to check with them as soon as we get our fingerprint appointment. If they don't have it, the social worker said that she would overnight it to them. Please pray that we can get confirmation that they have our approved homestudy.
