Yesterday I didn't know if they were vetted, and neither did anyone else. I have been researching the issue, and found the following thread that helped me with some of my questions. While the poster's references are his own media...which I normally roll my eyes at...I found quite a bit of information was useful. It is a long thread.
Again, I am FOR legal immigration, I realize that the majority of folks that are here in Central NE are only trying to provide a better life for their families, and often do the jobs that others won't do...but I want that to happen after the uncontrolled illegal entries are managed with a more secure border.
