Because you will never stop them without yet another government data bank and more tax money wasted. Once deported with nowhere to illegally return, how many do you think will go through the hoops of legal immigration to return? Maybe those willing to do that love this country enough to contribute. Many have lived here since birth because I think we send even the so called dreamers back to start over legally anchor baby or not.
Because you think we can’t keep those we’ve deported out, we should make it legal for them to return? That makes no sense at all!
Would you have the same for those who have committed violent crimes while here as well? I imagine not, so I see no reason to legalize especially those whom you’re certain will just break our laws again.
And—we’ve already imported with legal credentials a century’s worth of low-skill immigrants from third-world countries. Masters or above in STEM fields would be about the only ones I’d welcome here for the next decade.
Oh, and BTW, those who have been here since birth are legal US citizens according to our present laws.
