Master 8, I asked you earlier regarding b2 extension. Earlier we submitted extension application for my parents and forgot to attach the check in the package. Since the expiration of stay would expire soon, following your suggestion and we submitted a total new application with $580 fee prior to the rejected package arrival to us. But today we received the second rejected package with the same reason:--check amount is incorrect or has not been provided. Could you help me on what we should do? What's wrong with our applicaiton. I believe $580 for two applicants is correct. Can I resubmit the second returned package one more time? Do I need to write a letter to them? If do, could you let us know how to write?
