Stop all Immigration to the United States

The truth is, we’ve outgrown immigration. In large part, it does not benefit America and Americans, but rather, imposes costs and burdens.Immigration is a luxury we can do without, indeed, which we can no longer afford. We need another 4 decade immigration pause, in order to give those here legally the incentive to assimilate, and become and live as full Americans, or self select for return to their countries of origin. Not to mention, of course, deporting as high a percentage as humanly possible, say 90%, of those here illegally.
