I'll play.

These Green Card holders are trying to follow the rules and go through due process. They pick the wrong time to leave the country and get screwed in the deal. Yes, some are coming from countries with no infrastructure. This might be a reason why they are leaving? A lot of Iraques helped the American military and have vouchers from those superiors expressing their help and allegiance. Should they be left swinging in the breeze?

I get that Isis and other terrorist cells are using lacks immigration as a means to further their BS but do the legitimate immigrants have to pay that price? Hell, bring in the green card holders and take extra special care of them til they are vetted.

If a terrorist wanted to enter the country and do harm, using the Mexican border is far easier than any other port.

Yes, I am "America first" but I also come from immigrants (Scotch/Irish). Maybe 250yrs ago but the same animosity was in place then.
