I sorry to hear this. I know this is a painful time.
So how many times have you visited your husband and for how long?
How long have you been together and been married?
You said you have a lawyer, what are they doing as far as finding out getting the transcript (yes it's possible) of the actual interview. You paid for a lawyer make them work.
Also go to the Ghana forum there's a thread of all that latest denials (and its alot).
