We received I-797C after filing appeal form eoir 29 at the local office. The I797C does not have a receipt number; it says " EFRS - Applicant Receipt" at the top and " Customer Copy: Retain this copy as official documentation of your payment" at the bottom. It also lists my name and A number. Without a receipt number we can't check the case status online. This appeal was filed since last year and the BIA still hasn't received it.
