Does he wants to get married and bring his spouse with him , is that the question or when is a good time to get married for a DV winner?

Is he ready for marriage????? He or she does not need to be getting married just because he/she got DV.   If his DV serial number is after 13000 may be in waiting list  for chance? and may not be able to get visa? What happens to her dream to go to USA? Again once you come to USA, you may have different vision and idea and may regretted marrying in Nepal because you just married to have and bring spouse with you. Your taste and choice may alter once you board to USA and what if you start liking others and start seeing and experiencing unmatched and difference in thinking and no understanding but only compromises?????????

Any way, he should get married before he files the paper work and he must add his spouse info and marriage certificate in that paper. I know on gentleman married a woman after dv lottery winning and went to USA.

Good luck
