ghana-usalove

I have been to Ghana three times. Spoke to her mother and have met cousins, aunt, uncle, brother, sisters, grandmother. They know me and that we are together. Her reason for not disclosing is that she believes that people close to her may have bad intentions and can do spiritual things to prevent an approval at the embassy. When I went to marry, she did not disclose to any of them that I was there. We had a small ceremony with a few of her friends. The first two visits, family was always present.

My wife in Ghana refuses to tell her family about our marriage. States it will make things "difficult and create problems" for her. Will this not be a guarantee denial at the embassy as we have no joint assets, have never lived together, and haven't spent much time together? I thought we would need several statements from family and friends to say that they are aware of our marriage, especially from her side. Can anyone tell me if i am correct with this assumption? I feel almost a guaranteed denial coming because nobody in Ghana knows about the marriage. Interview is coming up hopefully within a few months but she does not listen to me. Any advice?
