This could mean anything. What's a "terror-prone" region? Any country in the middle east? What about those who were already here?

I'm not sure what things he has power to do but I do hope that the liberal states like California and Washington do to him what Texas had done to Obama. Sue everything he does. We may not win, but it would buy time until the next election. Those of you who live in california and still have some status should write your liberal congressmen, mayors, and governor and urge them to sue Trump if he tries to remove DACA and executive actions. If they find a friendly court, the injuction would buy a year and the appeal will buy another year. By the time it reaches the then conservative supreme court, it will be the mid-term elections.

You have SOME power to do something here so go and do it.
