I saw the news all over in NYT , WSJ , UST and on major news broadcasters from the US or EU.
While I think that this action will not affect DV on the short terms, executive action may draw some new lines on immigration policies and offer coverage against deportation to millions of illegal aliens in the US.
If this package will not affect DV, I am pretty sure that the lottery will remain safe until after 2016 elections or beyond.
From what I understand, he's made it clear that he will exercise his executive power in order to sort out immigration policies. I think the big worry for a lot of us is whether he will use executive power to pass through the latest Immigration Bill in which the DV lottery will be canceled. Looks like we'll find out soon enough.
