Thank you for the good job you are doing here. I was recently (15th March) denied diversity Immigrate visa based 212 (a)5 on winning with a name without a middle name and filing the visa application form (ds260) with a middle name as it appeared in my passport. I submitted documents baring both names I. E marriage certificate, secondary school cert. , employment letter all have the winning name. The CO sheet she gave me wasn’t addressed to me, date or her name. Later realised my police clearance wasn’t returned to me. I have gone ahead to make a statutory declaration on both names hence, do i stand a chance to get my visa and how do i go about it?

Hello CO, I was just denied an immigrate visa (dv lottery visa) last week base on the merit that the winning name is different from the one I used on the visa application forms. It's just the same name but included a day born name in the middle.
I was just trying to follow instructions as stated on the right side of the forms to write the name in the passport. I have then gone ahead to swear an affidavit on the name. What can I do next? Can I petition? and do I need a lawyer to see to that. Do I still have a chance?
