You’ll need to formally get married in order to obtain a marriage certificate which you’ll need to present as evidence of being married.
Now, considering the high rate of denial in Ghana, you’ll need to be prepared beyond presenting a marriage certificate in order to convince the IO your marriage isn’t a sham marriage or one entered into simply for the benefit of obtaining an immigration benefit.
As an aside, I’ll have to point out one of the reasons you’ll be under extra scrutiny is the fact you said you guys were traditionally married as at the time of the eDV registration but your wife entered as single when in fact she should have selected married as her marital status. This is not likely going to be a straightforward case.
Usually what we see is the other way round, people entering as married when they only have a traditional marriage. Anyway if it’s been a traditional marriage for any amount of time, they presumably have good evidence of a proper relationship. Will need this because Ghana is high fraud,
It's a bit of a anomoly. There are countries where the traditional marriage has the same legal rights as a civil marriage. USA immigration rules accept those marriages. However, I always recommend someone gets a civil marriage before interview, based on the way they have handled cases in the past.
Defacto marriages now don't have the same recognition in US immigration law at this time, and we have seen cases disqualified over that. To me, that's odd, but who said law was always sensible.
So she was single when she entered, and then you only got married after she knew she was selected?
Do you have evidence of your relationship together before the marriage ceremony and especially before her selection?
She was SHS student when she entered the lottery so we got married after she completed school few months her compliting school.yes we have pictures together and some chat but most of our phone chat is lost because I changed my phone but we have much pictures together
Because traditional marriages are recognized in Ghana, the wife should have entered as married if they had already done their traditional marriage before the eDV registration. Then as a DV selectee they can now follow up with a civil ceremony in order to obtain a marriage certificate. A CO who understands the culture over could very well decide she did not follow the instructions by adding her spouse.
You will need evidence of the traditional marriage. Pictures during the ceremony will help a lot. Traditional marriages are registerable and recognized. That's what you should have done. That was how I married. We then went to the court to do the registration.
Are you referring to "knocking" when you say traditional marriage? There's no legality with "knocking" and cannot be registered, but you should have picture to prove. This, together with the court registration you plan having will get you through. To explain the terminology to other readers, "knocking" is akin to engagement in the western world, but a few family members may be present as witnesses.
Also, prior correspondences, pictures together, (with her) and with her family, in functions attended, etc. will also help. Anything that proves that you have had a long standing relationship before she won the lottery.
