Of all the points in the immigration bill that's being debated in the senate right now, one of the most contentious is the question of who should get a green card. For years, the system gave preference to families, and keeping them together. Now, that could change. The new system would be based on merit, and skills, instead. Some call that elitism, others say it's just good economic sense. If it was up to you, if you had to write this one part of the bill, WHO would you let in?
