His folks broke the law and since they will be sent back to their country of origin it is only right that their child accompany them. Call it family values. Then the family can apply for citizenship like the families who abide by our law, stand in line, and wait their turn. This child should not enjoy the privileges of citizenship before the child of immigrants who have not broken the law. That's the American way.
I'm afraid it's not, since the American way is defined first and foremost by the plain words of the Constitution. It can be amended, but as it is, it states that those children are American citizens. I do know of people in this situtation whose parents were sent back to wherever, taking their child with them. Later the child returned and they are citizens. One gal, who sounded like any South Texas Tejano, had just gotten her associates degree, the other had only "fair" English skills and worked at a fast food Taco joint. Both are people you would like to call friends, which I do, and you'd also like them living next door, or watching your back.
