The Sixth Circuit has reversed the denial of an appeal for failure to file a brief, when the non-citizen did timely file a brief, but it contained an address for her attorney that was different than was provided on the Notice of Appearance. “[N]othing in the BIA Practice Manual, notice of appeal form, or regulations say that this address needed to match the address provided on the attorney’s notice of appearance or that failing to do so might result in rejection of the brief.”
