This whole visa lottery program is an outrageous assault on America. The main instigator of the program ten years ago was ... Ted Kennedy (that's a fact).
I know one Japanese woman who was married to an African. They were living in Japan. The husband insisted his wife apply for the lottery (she wasn't really interested). She won a visa, so she and her husband immigrated. Now the husband, who's a permanent resident, has brought in over one dozen of his relatives after petitioning for their visas. They all live in one slum-house. This kind of "cascading immigration" based on the original entry of just one family member is what's turning many of our urban areas into third world tenements.
He was the main instigator a long time before that. Do you know why the law reads that merely belonging to a terrorist group or making terrorist threats is not sufficient grounds to be denied a vias to the U.S.?
It's because Teddy boy forced that into the law so his IRA thug friends could come to the U.S. to raise funds to blow up more people back home.
