That isn't a reasonable premise.
The best policy would be to:
1. Secure the border
2. Deport all illegal aliens who break a law.
3. Enforce E-verify.
4. Enforce employment laws.
5. Pass a law denying illegal alien access to welfare.
Remove the incentives and the vast majority of illegal aliens will self-deport.
After several years of vigorous enforcement, we can take stock and determine what's next.
6. Fine employers $ 1,000 per work day per illegal alien.
Your ideas do not take into account those who’ve been here and have children who have been born here and/or grandchildren born here.
There is no removing these folks. US citizens are permitted to have their parents and grandparents visiting with them. That throws EVERYTHING out of kilter.
We need to change the anchor baby law, but that will not be retroactive to those already made US citizens.
Everybody seems to forget the anchor baby law and visitation by relatives being fine and dandy with immigration. But the US Constitution forbids any ex post facto law.
