Hope your response on the RFE is complete and responsive, you only get one chance usually (can do motion to reopen if "new" facts or motion for reconsideration if your response was not properly considered). Good luck. Thanks for the blessing!
You didn't read the form instruction, right?

You should retain an attorney to review all the facts specific to your case in order to receive advise specific to your case. The statement above does not create an attorney/client relationship.
