I received H1B i797c receipt on 05/07/19 with Notice date 05/07/19. When i enter my WAC19-aa-bbbbb receipt number, my case status (USCIS) website results in validation error: “My Case Status does not recognize the receipt number entered. Please check your receipt number and try again. If you need further assistance, please call the USCIS Contact Center at 1-800-375-5283.”
Is there something wrong?
