Tempmoana, I believe you missed the point.  You are right about Farook’s wife not being from one of the six countries in Trump’s travel ban, but your reply to Scuddrunner was not confined to Trump’s travel ban only.   You said “What makes you think that? If you are a terrorist, then chances are extreme vetting-- employed by Obama and Trump-- will block you.”  You threw in Obama. The point I made is that Scuddrunner is right; it is possible for a U.S. citizen or legal resident intent on committing acts of terrorism in the U.S. to bring in a “fiancé” accomplice from any country using the K-1 visa program.  With same sex marriage now authorized in the U.S., “fiancés” can be of the same sex as the petitioner, which makes vetting a bit more difficult.  A same sex fiancé from a Muslim country should wave a red flag in the vetting process, but I would not count on it.
