Unfortunately, a child is not proof of a genuine relationship. I don't understand this at all, why phone records and post-cards would be more proof, but somehow that's the way it is.
Start documenting everything you can now, and start calling from a mobile or landline that has itemized phone bills.
I know the stories about Accra are scary. I have a 2 year relationship that is completely genuine.
I have visited him 7 times when he lived in London, and once in Nigeria where we were married. We have phone and skype logs showing 3 hours a day communication for the past 2 years. We have nearly a hundred postcards and letters, we have daily emails, thousands of text messages, hundreds of photos together, letters from his family and my family, gifts (some expensive, like a lap-top and an iPad) with receipts, receipts from hotels we have stayed at, screen caps of him talking to my kids on skype, and talking to my friends. Screen caps of all the congratulations messages on Facebook, emails between his family and me, and my family and him....
yet still I am terrified we will be denied, or take 2 years waiting for an interview in Accra.
All I want to do is be with my husband and start a family with him. If I won $5 million in a lottery today I would happy give it up if I meant he could be in Canada immediately.
I have gathered a lot of great information on this forum, and I know we will be submitting a perfect application, but sometimes having so much knowledge (like what canadianwoman is going through) might be a bad thing.
