I am DV2010 winner from Bangladesh. I have married in 2003. But till now we dont have any child. We both are under treatment. Now my asking is 1) Would it be any problem to prove her as my wife? (I've mentioned her in my application and 1st letter). We have our marriage certificate and pictures at the time of wedding or later. Are that enough? 2) You know Bangladesh government has given National ID card to all of the adult citizens of Bangladesh in 2008. Me and my wife have gotten our National ID card before applying for DV2010 lottery. In my wife's card it is writen my full name as her husband. Should I show her ID card with other required papers to prove her as my wife at the interview?
